Ming Wei Lee, Kok Hwa Yu, Yew Heng Teoh, Han Wei Lee, Mohd Azmi Ismail
Page 1 – 9
AbstractThis study presents a numerical investigation on developing flow of inelastic nonNewtonian fluids in a circular tube having alternating superhydrophobic grooves and ribs arranged transversely to the flow direction. Laminar, steady and incompressible flow of non-Newtonian power-law fluid flowing in a circular tube having superhydrophobic transverse grooves of L = 0.1 and delta = 0.5 is considered. The influences arising from the presence of superhydrophobic surfaces (SHS) on radial velocity profile development, centerline velocity distribution and hydrodynamic entrance length are examined. For Reynolds numbers ranging from Re = 1 × 10^-4 to Re = 1, numerical results show that the hydrodynamic entrance lengths arising from flow over superhydrophobic transverse grooves for non-Newtonian fluid with powerlaw index in the range 0.5 ? ? < 1.5 are consistently longer than that of smooth surface.

Flow Characteristics of Transition Region Between Laminar and Turbulent Gas Flows Through Micro-Tubes
Kenshi Maeda, Chungpyo Hong, Yutaka Asako
Page 10 - 19

AbstractFlow characteristics in the transition region between laminar and turbulent gas flows through micro-tubes were experimentally investigated. The experiments were performed for nitrogen gas flowing through two stainless steel micro-tubes of D = 124 and 162 µm and two fused silica micro-tubes of D = 100 and 151 µm. The Mach numbers and gas bulk temperatures at the inlet and locations near the exit were also obtained by measuring stagnation temperatures, stagnation pressures, pressures at locations near exit and mass flow rates. The average Fanning friction factors also were obtained. The mass flow rate levels off in the transition flow region for micro-tubes as the stagnation pressure increases. The Mach number increases with an increasing Reynolds number in the laminar flow region. However Mach number decreases when Reynolds number goes higher in the transition flow region since the mass flow rate stays nearly constant with an increase of the stagnation pressure in the transition flow region. On the other hand, the bulk temperature increases in the transition flow region. This was validated by measuring wall temperature of micro-tubes whose outer walls are thermally insulated. The decrease in Mach number and the increase in the bulk temperatures in the transition flow region are the dominant scaling effect for the smallest diameter micro-tubes.

Page 20 - 30

AbstractEffect of Coriolis force and magnetic field on thermal convection in an anisotropic porous medium has been studied numerically. Linear stability analysis has been implemented to verify the presence of Coriolis force and magnetic field on the thermal convection in a horizontal anisotropic porous medium heated from below. The Darcy model is used for the momentum equation and Boussinesq approximation is considered for the density variation in the porous medium. The eigenvalue problems of the perturbed state were obtained from a normal mode analysis and solved using Chebyshev Tau method numerically with respect to upper free conducting and lower free conducting boundary condition. By using Fortran software, it is found that the thermal anisotropy parameter destabilized the system while the effect of Coriolis force and magnetic field help to stabilize the system and can delay the onset of convection and mechanical anisotropic parameter advanced the onset of convection in the system.

AbstractSolar intensity, collector design and its orientation are the key parameters that affect the performance of any solar collector. This work presents mathematical modelling of solar radiation for studying the effects of collector slope angle on the radiation falling on a solar collector and the determination of the collector optimum slope angle for Kano, Nigeria (12.05°N). To study such effects, two computer programs were developed for studying the effects of solar collector slope angle and optimization of the collection which was carried out using Engineering Equation Solver (ESS). Results showed that for maximum energy collection over the year, the collector should be tilted (in the order of priority); to the optimum angle of each month, to the seasonal tilt angles (i.e. horizontal from April to September and then set to Kano’s latitude plus 15° for the other months) or fixed to the latitude of Kano. Sloping of solar collector to the monthly optimum tilt angle results in significant radiation gain throughout the year with 28.6 and 24.8% in December and January respectively. Also the maximum radiation obtainable in each month is received and there will be no radiation loss throughout the year. Also energy received by the collector for generating hot water or steam in solar thermal collector was found to be affected by the collector’s orientation and slope angle.

Page 43 - 58

AbstractThe thermal convection in a horizontal binary fluid layer saturated an anisotropic porous medium with the effect of non-uniform temperature profile is studied analytically by linear stability analysis. The generalized eigenvalues problem subjected to various boundaries conditions are solved numerically using Galerkin method. The effects of solute Rayleigh number, Lewis number, mechanical anisotropy and thermal anisotropy parameters corresponding to the six basic temperature profiles on the stationary thermal convection are shown graphically. It is found that the effects of thermal anisotropic parameter, Lewis number and solute Rayleigh number are to reinforce the stability of the system while the effect of mechanical anisotropic parameter is to advance the onset of convection.

AbstractRenewable energy is an alternative approach of energy supply that meets the needs of the present generations without compromising the ability of future generations to meet their own needs. One type of renewable energy is solar energy. Solar energy systems convert solar energy into useful energy. In designing a solar collector, there are predictable and unpredictable parameters that are considered. Predictable parameters include performance characteristics of collector and mainly concern weather data such as solar radiation, ambient temperature, wind speed, direction, and other parameters is performance characteristics of collectors. This work analysed the use of the f-chart method in design liquid solar heating systems due to its simplicity and ability to estimate the fraction of total heating load supplied by the solar heating system. This method is very commonly used in designing for both active and passive solar heating systems, especially in selecting sizes and type of solar collectors that provide the hot water and heating loads. In this research, the data of the project is analysed to calculate based on the f-chart graph. The results show that the area in Melaka around the vicinity of Ayer Keroh is suitable for the installation of the flat-plate solar collector. The total annual heating load of domestic hot water in Melaka is 9.55 GJ and the annual fraction of the load supplied by solar energy is 78.42% which is suitable for implementation and installation in Ayer Keroh, Melaka.

AbstractThe utilization of geothermal energy needs to be improved to support energy diversification and sustainable environmental development. Applying heat pipes as a heat transfer device, will overcome several obstacles to increase the use of geothermal energy, especially low enthalpy geothermal energy. The objective of this study is to investigate the thermal performance of heat pipe usage for heat distribution from low enthalpy geothermal fluids to agricultural dryers. Geothermal fluid simulator (hot water) uses water that is heated by 9000 Watts heater and is flowed by a pump. The heat pipe has a length of 700 mm OD 10 mm, while the heat pipe filling ratio is 50 %. In this experiment, the number of heat pipe used are 42 pieces. The condenser uses a total of 181 fins with a size of 76 x 345 mm. Fin from aluminum material with 0.105 mm thickness is used in this experiment. The result show that the heat pipe could be carried out as a Heat Pipe Heat Exchanger (HPHE) in applications of low enthalpy geothermal heat. The value of HPHE effectiveness increases as the increase of hot water temperature on the side of the inlet evaporator and tends to decrease as the air velocity increases. The biggest HPHE effectiveness value is 61,427 %.

AbstractHotspot related problem can be detrimental to Sulphur Recovery Unit (SRU) material lifespan. One of the causes of the hotspot is susceptible high vibration level of multi components in SRU. In this project, the vibration level of the sulphur recovery unit was experimentally measured. The main objective of the measurement is to technically assessed the unit for maintenance management purpose. Two types of measurements were performed. Firstly, bump tests were conducted to accurately determine the natural frequency of the oxygen intake pipeline. Secondly, the vibration level is then mapped to various components in the system according to the process conditions. By analysing this map, the correlation between the vibration levels, natural frequency and process conditions that can cause excessive vibration of the SRU can be specifically verified.

Page 88 - 99

AbstractThis paper discusses the methods to obtain a correlation of local thermal resistance for heat transfer of a double-layered microchannel heat sink (DL-MCHS) with parallel flow configuration. Based on the energy balance in a thermal resistance network constructed for the DL-MCHS, the local thermal resistance which consists of conductive, convective and capacitive thermal resistance has been obtained as a function of governing parameters including the channel geometrical parameters. The results predicted for different channel width with the correlation are compared with the results obtained through numerical. Good agreement was found between simulation and correlation results, which indicates that this correlation could be used to predict the local temperature along the flow direction for DL-MCHS with different channel width.

Page 124 - 132

AbstractNanofluid has been drawing attention in various engineering applications in past decade due to its superior heat transfer characteristics than conventional working fluid. From past researchers, it is found that behavior of nanofluid can be greatly varied by various factors such as method of preparation, concentration/type of suspended nanoparticles and type of base fluid used. Due to the desire to possess nanofluid with more advantageous characteristics, dispersion of different nanoparticles into base fluid has led to a novel product which is called hybrid nanofluid. Different types of hybrid nanofluid were prepared and studied by former researchers in accordance with parameters required in their studies. Based on literature review, hybrid nanofluid shows greater heat transfer performance and rheological properties compared to base fluid and mono nanofluid. This paper reviews the preparation method, stability investigation method, thermophysical properties and heat transfer performance of hybrid nanofluid in various heat transfer applications. Apart from that, this review outlines challenges regarding hybrid nanofluid and some suggestions to improve future researches in this area.

AbstractPhotovoltaic (PV) panel is directly converted solar irradiance into electrical energy. The temperature of the PV panel increased as it absorbs solar irradiance lead to a reduction in its output power. This undesired impact can be prevented through the use of a cooling system with PV panel. In this research, a water cooling system was designed to the PV panel in order to reduce its temperature. The objective of this research is to predict the temperature distribution of the PV panels without and with water cooling system. In the water cooling system, the water flow over the front surface of the PV panel in order to reduce the temperature of the PV panel. In addition, this research also focused on the impact of inlet water temperature on the performance of water cooling effect. The result of this research shows that the average temperature distribution of the PV panel without water cooling system is higher than that with water cooling system. The average temperature of the PV panel without cooling system is 50.68 °C. For the water cooling system, the PV panel with the inlet water temperature of 20 °C can be reduced the temperature of PV panel by 15.63 °C as compared to the PV panel with inlet water temperature of 45 °C. This research could be beneficial for researchers and students to understand the effects of temperature to the PV panel.

Jia-Wei Zuo, Kok-Cheong Wong, Hoon Kiat Ng
Page 147 - 156

AbstractThe present study numerically investigated the thermal performance for three-layered microchannel heat sink (MCHS) with horizontally tapered channel profile. The problem is solved using a three-dimensional conjugate heat transfer model. Parallel flow and counter flows configurations are investigated for their maximum thermal resistances. The effects of different tapered geometries of microchannel within the multi-layer MCHS are investigated by varying the channel inlet width and channel outlet width. The numerical results show that the three-layered MCHS with CF1 flow configuration give the lowest value of thermal resistance for low value of channel inlet size (converging channel profile) while the parallel flow configuration shows lowest value of thermal resistance among all the flow configurations at high value of channel inlet size (converging channel profile). The results also show that counter flow configurations alter the peak temperature location at the base of heat sink along the flow direction toward the center of the channel, rendering better temperature uniformity.

Tribological Analysis of Modified RBD Palm Kernel Containing Anti-oxidant Additive using Four-ball Tribotester
Muhammad Arif Dandan, Syahrullail Samion, Wan Mohamad Aiman Wan Yahaya, Faris Hadi
Page 157 – 164
AbstractVegetable oils are becoming increasingly important as an alternative lubricant oil due to their non-toxic, renewability and biodegradability characteristics. They are considered as promising candidate to replace the conventional petroleum based lubricant which are constantly threatening our environment. However, most of the vegetable oils are facing common issue which is low oxidative stability that limits them to be used directly as bio-lubricant oil. This work studied the application of TertiaryButyl-Hydroquinone (TBHQ) as synthetic base anti-oxidant agent inside palm kernel oil (PK). The effect of load on the tribological performance of lubricant formulated were tested using four-ball tribo-tester according to ASTM D4172 standard with duration of 60 minutes for each test. The results obtained were compared to the commercialized mineral (MO) and semi-synthetic engine oil (SSO) for the reference purpose. Based on the result obtained, the coefficient of friction of palm kernel is smaller as compared to commercialized petroleum based oil. This is contributed by the presence of long polar fatty acid structure that acts as a protective film between two rubbing surfaces. The addition of anti-oxidant, TBHQ also helps to further reduce the friction coefficient of PK. However, the wear scar diameter of PK and PK+TBHQ are larger compare to MO and SSO. Thus, it can be concluded that TBHQ manage to enhance the friction reducing performance of PK by lowering the value of friction coefficient. However, there is still room improvement for the anti-wear properties of palm kernel oil.

Page 165 - 174

AbstractIn this study, the problem of MHD micropolar nanofluid boundary layer flows over an exponentially stretching/shrinking sheet with radiation and suction effect is considered. The Buongiorno’s nanofluid model is applied to the problem. The governing equations are first transformed to the coupled nonlinear similarity equations by using similarity transformations. The resulting equations which is in ordinary differential equations form are then solved numerically by using shooting method. Triple solutions are observed to exist for the flows. A comparison with existing solutions in literature for specific case are made to assess the accuracy of the present results. Further, the flows profiles are examined, and it is found that the presence of suction parameter will contribute the occurrences of triple solutions.

AbstractThe present paper investigates the impact of velocity slip and thermal slip on the peristaltic transport of a Herschel-Bulkley fluid, flowing through a uniform two dimensional porous tube under the assumptions of long wavelength and low Reynolds number. The mathematical representations of temperature and velocity fields, pressure gradient, and stream function have been found through the closed-form solutions of the energy and momentum equations. Numerical integration has been employed to compute the frictional force and pressure rise. The influence of relevant parameters in the problem have been discussed and presented graphically. The results reveal the increasing effects of thermal and velocity slip on pressure rise and temperature. Also, trapping phenomena of the Herschel-Bulkley fluid is discussed. The volume of the bolus is observed to increase along with the velocity slip parameter.

AbstractThis study involved the performance of energy and exergy analysis on a 200 MW Steam cycle power plant (SCPP). The aim is to investigate the effect of using different number of feed water heaters (FWHs) on the cycle performance. Several simulation analyses were conducted in this study on a MATLAB platform. The computer model used was based on natural gas combustion, enthalpy balances, energy balances, and entropy changes of the SCPP. The real case study was simulated on a validated model of the SCPP for Shahid Montazeri Power Plant. The exergy destroyed within each components system and the exergy efficiency are determined to study the irreversibility of the system and identify the chances for the enhancement of the power system. Based on the result of the analyses, the energy and exergy efficiencies of the SCPP were determined to be about 37.52 % and 41.7 %, respectively. In the SCPPs, the combustion chamber (boiler) contributes the highest exergy destruction rate (around 48 % of the exergy value of the gas) among the main components of the power system.

AbstractSolar radiation could be harnessed to produce thermal and electrical energy. The solar thermal radiation is very advantageous as it can be harnessed easily and at an affordable cost. Electrical energy could be produced from the solar radiation by photovoltaic process and have an efficiency of 20-40%. This process is currently limited to its material and manufacturing costs, inefficiency under thermal load and relatively lower performance under low clearness index conditions. By using both properties, a solar photovoltaic-thermal (PV/T) hybrid could be designed to increase thermal and electrical efficiency during low clearness index. The study of the potential application of Thermoelectric Generator (TEG) in PV/T applications is highlighted to see the opportunities that are available in this field of study. Computational Fluid Dynamics (CFD) simulation using COMSOL software was carried out.

Page 248 - 256

AbstractIn this paper, an analysis is made for heat transfer unsteady flow of nanofluid over semi-infinite vertical plate with leading edge accretion/ablation. The impact of viscous dissipation in energy equation with Newtonian heating condition is also considered. Tiwari-Das model is used to incorporates the effects of nanoparticles volumetric fraction. Sodium carboxymethyl cellulose (SCMC) is considered as based fluid containing titania (TiO2) nanoparticles. Similarity transformations are employed to transform the unsteady partial differential equations into a system of ordinary differential equations. The transformed equations along with relevant boundary conditions are solved numerically by Runge Kutta Fehlberg fourth-fifth order (RKF45) method in MAPLE software. The analysis shows that velocity and temperature field in the respective boundary layers depend on different physical parameters, namely Prandtl number, Eckert number, Casson parameter, Newtonian heating parameter, accretion/ablation parameter and nanoparticle volume fraction. Temerature shows higher value for Blasius flat plate, while for Rayleigh-Stokes is the lowest.

Page 257 - 266

AbstractNanofluid has been drawing attention in various engineering applications in past decade due to its superior heat transfer characteristics than conventional working fluid. From past researchers, it is found that behavior of nanofluid can be greatly varied by various factors such as method of preparation, concentration/type of suspended nanoparticles and type of base fluid used. Due to the desire to possess nanofluid with more advantageous characteristics, dispersion of different nanoparticles into base fluid has led to a novel product which is called hybrid nanofluid. Different types of hybrid nanofluid were prepared and studied by former researchers in accordance with parameters required in their studies. Based on literature review, hybrid nanofluid shows greater heat transfer performance and rheological properties compared to base fluid and mono nanofluid. This paper reviews the preparation method, stability investigation method, thermophysical properties and heat transfer performance of hybrid nanofluid in various heat transfer applications. Apart from that, this review outlines challenges regarding hybrid nanofluid and some suggestions to improve future researches in this area.

AbstractAluminium Nitride (AIN) is classified in the 3rd nitride ceramic materials and able to emit the lights at shorter wavelength of 210 nm with high band gap up to 6 eV. In addition, with thermal conductivity up to 140 W/mK has made this material in demand for electronic devices applications such as light emitting diode, laser diode and photodetector for the ultraviolet region. However, previous researchers have confirmed the existence of defects in the microstructure of AlN that affected the properties of this material during the growth process. Hence, high-temperature annealing heat treatment is utilized as one of the methods to cure the problems of AlN thin film. Therefore, this paper is about to identify the effects of high-temperature annealing heat treatment on the microstructure of AlN. The changes on microstructure were observed through Transmission Electron Microscopy after the annealing process. The results showed an increase of the annealing temperature contributed to the reduction of defects in the microstructure of AlN.

AbstractFire can be formed when these three elements, hot, oxygen, and combustible materials, are present. It produces heat and light through a chemical process of oxidation reactions that occur rapidly. It is widely known that a human’s life on the earth cannot be separated from the fire. But we often hear a phrase about the fire: ‘friendly when it is small, deadly when it is big’. Based on this expression, we can say that the fire is not only furnishing benefits to humans but it also can destroy property and killed many lives each year. Therefore, a fire protection should be given priority in our daily life, especially the use of fire resistant doors in commercial and office buildings. Kapok, a natural fiber, which has a low thermal conductivity has been selected and examined in this study as a fire-resistance material. The objective of this study was to find the resistance of gypsum when mixed with kapok fiber. The laboratory works involved the preparation and testing of composite samples of gypsum and kapok fiber, which were prepared with different thicknesses, namely 6.4mm, 9.5mm, and 12.7mm. Then composite samples of three different compositions, namely 1000g of gypsum: 10g of kapok, 1000g of gypsum: 20g of kapok, and 1000g of gypsum: 30g of kapok were prepared for each of those thicknesses. All the composite samples were burnt, in accordance to MS 1073 (1996), in a combustion chamber that had been designed and fabricated in Combustion Laboratory, Faculty of Mechanical Engineering. The experimental results revealed that the composite sample of 12.7 mm thickness gave the highest fire resistance for all the prescribed compositions while the composite sample of 30 g of kapok fiber produced the highest fire resistance compared to other two compositions. In short, a composite mixture of gypsum and kapok fiber has the potential to be used as a fire-resistance material in manufacturing of fire resistant doors, walls, and ceilings for the building construction sector.

Numerical Solution of Boundary Layer Flow over a Moving Plate in a Nanofluid with Viscous Dissipation: A Revised Model
Siti Norfatihah Zulkifli, Norhafizah Md Sarif, Mohd Zuki Salleh
Page 287 - 295

AbstractModel of boundary layer flow over a moving plate in nanofluid with viscous dissipation effect is revisited. A new boundary condition is applied with the assumption that there is no nanoparticle flux at the surface. The nanoparticle volume fraction on the boundary is passively control rather than active control and this makes the model more realistic. A similarity transformation is introduced to reduce the governing non-linear partial differential equation into ordinary differential equation. The ordinary differential equations are computed numerically through numerical method namely Runge-Kutta Felhberg (RKF) technique. Validations of the result has been made by comparing the present results with results from the previous studies. In this study, it is found that the presence of viscous dissipation contributes to an increase in temperature profile. In addition, it is observed that an increment in Brownian motion parameter produce negligible effect on temperature profile. Furthermore, both nanoparticle concentration and temperature profile intensify with an increase of thermophoresis parameter.

AbstractThe combustion properties of torrefied mixture of empty fruit bunch (EFB) and polyethylene (PE) plastics were investigated experimentally, for weight ratio of 95:5 (EFB: PE) and 90:10. The mixture samples were obtained from briquettes that were produced under various briquetting temperatures (150°C-190°C). The torrefaction was performed at constant temperature of 250°C and at constant nitrogen flow rate of 1 l/min. Generally, it can be said that the combustion properties such as calorific value and moisture content fulfil the minimum requirement stated by standard for commercial briquette (DIN51731). In addition, it can be said that the effect of mixture composition on the combustion properties is stronger than the effect of briquetting temperature.

Page 10 – 22

AbstractThe present study analyzes in details to compare SIMPLE and SIMPLER algorithm in terms of their convergence rate, iteration number and computational time. The work which is based on primitive variables (u, v, P) formulation of Navier-Stokes equations to investigate the velocity and pressure distribution in the square cavity at Reynolds number of 100 and 400. The solutions are obtained for grid size 16 × 16 up to 256 × 256. From the plots of velocity profiles along centerline geometry, it shows good agreement with the benchmark solution from past researchers. The velocity and pressure in the cavity varies as the Reynolds number increases from 100 to 400. SIMPLER algorithm is proven to be more efficient compared to SIMPLE as iteration number required for a given Reynolds number and grid size is lower than that of SIMPLE. The values of under-relaxation factors for velocity components and pressure play significant role in terms of convergence rate of a numerical scheme.

Ehsan Kianpour, Nor Azwadi Che Sidik
Page 1 – 11
AbstractThis study was done to study the effects of cylindrical and row trenched cooling holes with alignment angle of ±60 degrees at blowing ratio of BR=3.18 on the film cooling effectiveness near the combustor end wall surface. In this study, a three-dimensional representation of a Pratt and Whitney gas turbine engine was simulated and analysed with a commercial finite volume package FLUENT 6.2.26. The analysis has been carried out with Reynolds-averaged Navier–Stokes turbulence model (RANS) on internal cooling passages. This combustor simulator was combined with the interaction of two rows of dilution jets, which were staggered in the streamwise direction and aligned in the spanwise direction. In comparison with the baseline case of cooling holes, the application of row trenched hole near the endwall surface doubled the performance of film-cooling effectiveness.

Page 12 – 20

AbstractEnergy conservation in buildings is given utmost importance today by organizations all over the world because an effective energy management in an enterprise leads to significant cost savings in addition to indirect benefits, such as extended equipment life, increased comfort, safety, and productivity. An effective and successful energy management program begins with an energy audit, which is a systematic approach for assessing energy end-use efficiency of all concerned systems/equipment.to identify energy conserving measures (ECMs). This paper analyzed the data obtained based on the extracted electricity utility bills and Automotive Gas Oil (AGO) consumption records for 7 years (i.e. from 2009 to 2015) for Kaduna Polytechnic, being the two energy sources, as well as site surveys and analysis of the energy end users present. The records have shown that, the institution consumes annually an average electrical energy of 1445448 kWh and an average of 11093.14143 liters of AGO, which is equivalent to 118918.48 kWh during normal operation. The result of the investigation and analysis of the energy conservation potentials in the institution have shown that, energy savings of up to 7.5% of the total energy can be achieved by switching-off all security lights during the day. While turning off the air conditioners in the early morning hours of between 8am to 10am would provide a saving of up to 10% of the total energy. Furthermore, a saving of 19.5% of the total energy can be achieved when the incandescent lamps are replaced with the energy efficient ones. The energy conservation measures (ECMs) followed in this research had shown significant savings in terms of both energy and cost, and if well implemented, can pave the way for a sustainable future towards energy management in the institution.

Norati Artini Awang, Haslinda Mohamed Kamar, Nazri Kamsah
Page 1 – 10
AbstractAir-conditioning (AC) systems are the most common energy consuming equipment in commercial buildings in Malaysia. An Ice Thermal Storage (ITS) application is capable of reducing the power consumption of the air-conditioning system and its corresponding costs as it transfers the peak of electricity consumption from on-peak to off-peak hours. In this study, an analysis was performed on a conceptual AC-ITS system to estimate the annual saving in operating cost when compared to an existing AC system installed at Perpustakaan Raja Zarith Sofia (PRZS) building located in Universiti Teknologi Malaysia, Johor. First, the cooling loads of the building based on the Carrier Cooling Load Method were determined. Based on the cooling loads the system equipment was selected. From the cooling load profile, the chiller-charging and -discharging scheduling of the ITS system were determined. The estimated annual operating cost of the present AC system is approximately RM 437,877. By employing the ITS-AC system, a potential saving of about RM 299,901 per year can be achieved, representing a 68.5 % saving per year.

Page 11 – 18

AbstractThis paper presents an investigation on the effects of using solar chimney, gable vent, and the combination of the two natural ventilations on the average air temperature and air-flow condition inside a double-storey house in Malaysia, using computational fluid dynamics (CFD) method. The representative model of the house comprises of a main hall, a kitchen and an upper hall. Both temperature and air velocity boundary conditions were prescribed on the model. Results of the simulation indicates that the average temperature of the air in the house at 1 pm closely matched the measured values. It was found that the average temperature of the air in the house is not so significantly affected by the types of natural ventilation used. Opening the kitchen door causes the air to flow from the main and upper halls towards the kitchen and causing a bottle neck at the pathways. A more uniform air flow is obtained when solar chimneys are used. When gable vents are used, high intensity air flow occurs in the main hall and it spreads uniformly towards the kitchen and upper hall. The air-flow intensity becomes even higher in the main and upper halls when a combination of solar chimney and gable vents are incorporated into the CFD model.

The Effect of Microbubbles on the Reduction of Biochemical Oxygen Demand (BOD) of Palm Oil Mill Effluent (POME)
Azrin Camillius Tan, Nadia Dayana Bahar, Wira Jazair Yahya, Ahmad Muhsin Ithnin
Page 9 – 14

AbstractPalm Oil Mill Effluent (POME) is a wastewater discharged from the palm oil industry. It contains large quantity of organic matter in the form of total suspended solids (TSS), volatile suspended solids (VSS), total solids (TS), oil and grease which is the major contribution to the water resources pollution especially rivers or lakes if left untreated. Raw POME has high value of Biochemical Oxygen Demand (BOD) which is more than 30,000 ppm, thus it must be treated before it can be discharged to the water resources. Therefore, this paper presents a new method of POME treatment using microbubbles. Microbubble is selected due to its high oxygen transfer coefficient at a low air flow rate that can give a major impact on reducing the BOD of POME. Thus, microbubble can be a factor on reducing the BOD of POME. The POME sample was collected and handled according to APHA standard. The duration of treatment was carried out for 120 minutes by analysing the BOD at the following time intervals; 0, 30, 60, 90, and 120 minutes with introduction of microbubble. The BOD results were measured using FiveDay Biochemical Oxygen Demand method (APHA 5210 B). The lowest flowrate of microbubbles performed better in reducing the Biochemical Oxygen Demand (BOD) with reduction of 26% of BOD at 60th minutes retention time. It is due to the lowest air flowrate produced the smallest size of microbubble whereas the bubble size is one of the key factors with significant impacts on floatation and mixing that affect aeration process.

Darminesh Sathuramalingam Pillay, Nor Azwadi Che Sidik
Page 1 – 13
AbstractThe biodegradable or vegetable oil possess good chemical properties competitive with mineral oil which can used as alternative lubricant. However, the vegetable oil has poor performance of tribological characteristics at high temperature and oxidation which causes the vegetable lubricant not used widely in industrial sector. To optimize lubrication, the vegetable oil can be mixed with hybrid additives. In this paper, RBD palm olein and soybean oil was mixed with single and hybrid additives which has been tested to determine its lubricating properties. The additives which has been used for the study was zddp and copper oxide nanoparticles. The mixing percentage of zddp has been fixed with 1% optimum whereas the copper oxide nanoparticles varies from 0.75% to 1% of the total mass. Testing has been conducted using fourball tribotester based on ASTM D4172 standard condition. The result shows that formulated palm olein lubricant with hybrid additive with zddp and CuO nanoparticles at 0.75% and 1% respectively provided 54.6% of WSD reduction, 29.2% COF reduction and smooth surface roughness compared with base RDB palm olein and soybean oil. However, in term of WSD and surface roughness, the mineral lubricant possesses better performance expect COF value of hybrid additive lubricant possess better value. From this results, it can be concluded that the performance of vegetable lubricant could be better enhanced with hybrid additives and its tribological characteristics competitive with conventional mineral lubricant.

Economics of Biogas Plants and Solar Home Systems: For Household Energy Applications
Md Mizanur Rahman, Mohd Faizal Hasan, Aminuddin Saat, Mazlan Abdul Wahid
Page 14 – 26

AbstractElectricity and clean cooking fuels are the two basic ingredients that are indispensable to alleviate energy poverty and bring about human development, but still today, globally, more than one billion people do not have access to these two forms of energy. The major reasons for the lack of these two energy services are economic constraints. Biogas plants and solar home systems (SHS) are two technically feasible renewable energy technologies to deliver cooking and electricity loads in rural areas. The negative economic perception (i.e. high cost) of these two renewable energy technologies is primarily responsible for making their diffusion slow in developing countries. This work presents a model to examine the economic performance (i.e. benefit to cost ratios) of these new energy technologies against three household load categories. Applying this model, this study shows that biogas plants used together with SHS show attractive economic performance e.g. a benefit cost ratio (BCR) of 6.6 for load Category 1(basic load). It is evidenced from this work that biogas plants together with SHS are economically promising in rural areas in developing country situations particularly in Bangladesh.

Page 1 – 8
AbstractIn recent years, there has been an increasing interest in heat transfer enhancement using nanofluids in corrugated channels due current devices become smaller and smaller and are expected to perform better. The devices will create hot spot and generate more heat are related to the devices performance are better and inability of current heat sink to remove heat. So, the aim of this project is to stimulate the nanofluids flow in straight channel and corrugated microchannel using ANSYS software with certain specific parameters to be fixed or stated which are hydraulic diameter is 133.3 µm, Knudsen Number will be fixed when flow is continuum, Reynold number will be below than 1400, so that the flow in within laminar region, the inlet temperature will be 300 K, uniform heat flux 100W/cm2 and inlet velocity will be in the range of 1.0m/s to 4.5m/s. This research will describe the procedure of using ANSYS software and to analysis the heat enhancement, pressure drop, velocity contour of nanofluids happen in straight microchannel compared to triangular cavities microchannel. The analysis proved triangular cavities that using high volume fraction of nanofluid has better performance compared to straight channel with the same volume fraction of nanofluid because the triangular cavities microchannel have the highest nusselt number and lowest friction factor whereby these two factors become indicator to thermal performance.

Erosion Prediction of Bypass Seat in Oil Well Auto-fill Equipment Using CFD Approach
Ahmad Rizal Maharam
Page 9 – 18

AbstractThroughout the course completion of oil and gas wells, it is important to run casing in a wellbore that is normally laden with wellbore fluids. The wellbore fluid, or mud, serves two essential purposes. First, it helps to keep the inflow of formation fluids into the wellbore by exerting hydrostatic pressure on the formation. The hydrostatic pressure that is applied must be sufficiently high enough to keep fluid inflow but not high enough to crumble down the formation. During casing run, the impacts of surge and swab must be considered when deciding casing running rates to ensure the boundary between the hydrostatic pressure column and formation pressure keep at equilibrium. Second, the mud assists to circulate cuttings from the wellbore during the drilling commencement. Occasionally during running casing in the wellbore, it is important to have dependable auto-fill equipment to help limit the surge and swab effect. The concept is enabling wellbore fluids to enter the casing from the lower end of the casing is called auto-fill or self-fill. Filling the casing consequently from the lower end wipes out the requirement for manual filling the casing from surface while running in hole (RIH) and casing running efficiencies can increased. In the event that circulation time and additionally rate while RIH or well conditioning surpasses pre-determined mud weight and flowrate, erosion on the valve could happen, which lead to higher than anticipated auto-fill deactivation rates. Thus, this study aims to assess flow behavior and erosion characteristics of the auto-fill valve assembly at the highest acceptable predetermined flowrate parameter.

Estimated Original Oil in Place Variation Due to Porosity Determination Technique
Ariffin Samsuri, Zainal Zakaria, Issham Ismail, M. N. Krishnamurthy
Page 1 – 10
AbstractOriginal oil in place underpins field appraisal, development, and management and at early appraisal stage, static volumetric technique had been used for estimation. One of the key variables in this technique is porosity; therefore the technique use for porosity determination will influence the estimated original oil in place magnitude. The evaluations of zone-average porosity in the net-pay intervals in a single well have accuracy of approximately 5 to 25 % of total porosity. This is largely the result of systematic uncertainty. Through this research paper, it is inferred that, the effect of averaging the porosity is more imminent on an inter-bedded reservoir rather than a clean sand reservoir. This is because the averaging effect is not accounting the porosity changes in smaller scale, as it is wrongly assumed; changes in smaller area of reservoir are negligible. This fundamental approach is proven to be incorrect. Though in clean sand this averaging method is still applicable, it is proven that an averaging method is not suitable to be used in a laminar or inter-bedded reservoir. The difference that may be introduced is almost 25% of the original oil in place, which may affect the economic model as the potentially producible and sub-economic field or discovery.

Abubakar Sadiq Aliyu, Abdulkarim Ali Deba, Haruna Saidu
Page 11 – 22

AbstractIncrease in global development of renewable energy sources as sustainable alternatives to the conventional fossil fuels witnessed in recent time is linked to greenhouse gas (GHG) emissions; high dependency on imported fossil oil especially in the developed world; non-renewable nature of fossil fuels; price volatility of petroleum products and instability in the oil producing areas. Therefore, bioenergy appears to offer hope for addressing these concerns while also providing new opportunities for farmers in developing and developed countries alike. Among the many possible resources, biodiesel has received the most attention as a promising substitute for conventional petrol-diesel fuel. The production of biodiesel (methyl esters) from Jatropha plant is currently generating interest in every economy of the world as an alternative means of producing liquid fuels from biomass and have gather relevance due to the environmental advantage the process offers. Biodiesel is a renewable source of energy that can facilitate clean air, readily usable in existing engines and transport facilities, capable of generating employment and income for citizens but has not been fully tapped. Hence, efforts are being made to explore this economically competitive, environmentally acceptable and readily available alternative source of energy. Therefore, the paper provides a review of Jatropha as a feedstock for biodiesel production in Nigeria. Focusing on biodiesel development from Jatropha feedstock, the objectives of reviewing its current trends in the production of this biofuel will hold an immense benefit. The biodiesel fuel properties and potential of Jatropha towards environmental sustainability, poverty alleviation, and more importantly improve economic development for rural communities were highlighted.

Biofuel Development in Nigeria: Prospect and Challenges
Abubakar Sadiq Aliyu, Abdulkarim Ali Deba, Haruna Saidu, Ibrahim Ladan Mohammed, Mohammed Maikudi Usman
Page 1 – 9
AbstractBiofuel is perceived as a means to ease global energy concerns, promote rural development and mitigate climate change. Therefore, its development has been and will continue to be a priority for most countries. Presently biofuel production is not economically viable, and the drive for its production is driven by the policies of some countries that perceive it as the only possible alternative to fossil fuels and a way out from the declining world crude reserves. Since biofuel offers the opportunities for developing countries to grow new livelihood and reduce the over dependence on imported fossil fuel, as well as obvious benefit to the environment, Nigeria is not left out. Therefore, for Nigeria to step into the biofuels industry in a big way, with every sector being placed in the use of cleaner renewable energy, government need to plan towards producing biofuel from her abundant biomass resources. This idea is expected to boost Nigerian economy through cultivation of arable landmass for provision of feedstock. Therefore, the quest for biofuels no doubt, represents a legitimate ambition. It is in the light of this that the paper reveals the prospects and challenges of biofuel development with the objective of reviewing the current situation in Nigeria. It further identifies inadequate process technology, poor policy implementation and lack of public acceptance as factors hampering its success.

Page 10 – 20

AbstractThe conventional refrigeration systems use fossil fuels for their energy inputs. Due to the growing environmental degradation and fossil fuel depletion issues, energy supply from alternative sources is gaining huge attention. Solar driven refrigeration system, which uses solar energy as its energy input, not only addresses these challenges and but also enhances sustainable development. In this work, we have developed a smallscale solar driven refrigeration system by combining several components such as a solar panel, a charge controller, a compressor, an inverter, an evaporator-tank, a condenser and a few connection wiring. We have operated the system for several days to check its functionality and performance. During operation, we have measured solar panel’s current and voltage with a 5-minute interval to calculate power that has been supplied as an input to the compressor. The evaporator coils pass through the water tank to cool down water to a desired temperature (i.e. 4 ºC). The temperature of the evaporator and condenser was also recorded for calculating the cooling effect created by the refrigerant R-134a. We have calculated coefficient of performance (COP) of the system for both actual cooling load of water and cooling effect created by the refrigerant. The refrigeration system successfully operates with an actual COP of 0.95. Despite the COP is low, the solar driven refrigeration system, which does not require any fuel, is a promising option in regard to both environment and economic aspects.

Page 1 – 17
AbstractA portion of rural and remote areas in Malaysia still do not have access to grid electricity and in near future they are unlikely to get grid access. Lack of electricity in rural areas jeopardises development and exacerbate the poverty. Decentralized offgrid rural electrification system that integrates various renewable energy sources became inevitable for areas where grid connection is neither available nor feasible. Moreover, designing and implementation of efficient and techno-economically viable off-grid electric supply is a challenging task. A hybrid combination of renewable energy technologies is appeared to be a suitable candidate over grid extension for remote areas. In this study, we model viable off-grid rural electrification system for a remote village Kampung Sungai Tiang located in Belum, Perak. We consider prospective electricity demand of the village and utilize available renewable resources to generate electricity to fulfil the demand. An optional diesel generator has been considered as backup power supplier whenever the renewable technologies cannot support the demand. This study implemented HOMER software to determine optimum electrification systems for the village and evaluate their techno economic performance. The simulation results reveal that Hybrid PV-Diesel-Biomass system is a better option to be implemented in this village in regard to viability, techno-economic performance, and environmental friendliness.

Page 18 – 31

AbstractThe aim of this study is to simulate flow over two types of generic vehicle model. The simulation is done using the open source CFD solver, OpenFOAM, which is based on the finite volume method, where each of the control volume is treated for its flow physical conservation using governing equations. The two different generic vehicle models are SAE Type 4 (fullback) – strongly simplified model and DrivAer Fastback – a more realistic vehicle model. Their flow structures are compared based on the CFD results. The different in flow behaviours are shown clearly by each model due to the geometry differences, where the SAE Type 4 is blunter, while the DrivAer Fastback is more aerodynamic. Results showed that SAE Type 4 model able to produce large turbulence wake structures and thus lead to higher value of drag coefficient compared to the DrivAer Fastback model. The drag coefficient for the SAE Type 4 is 0.3722 and the DrivAer Fastback is 0.2803.

Nasir Salim Hassen, Nor Azwadi Che Sidik
Page 1 – 9
AbstractThe main objective of this study involved testing of nozzle type, driving speed and wind speed effects on atomization parameters for broadcast spraying application. Two broadcast nozzle types flat fan extended range XR11003 and flat fan drift guard nozzle DG11003 were tested under wind tunnel conditions. To validate spraying results, the reference nozzle of spraying systems flat fan TeeJet nozzle TP11003 was used for comparison. The results of this study indicate an obvious effect of the technical variables and wind variable on atomization parameters. The nozzle DG11003 produced droplet size spectra of D0.1, D0.5 and D0.9 bigger than the extended range nozzle and reference nozzle. The droplet size spectra became smaller under increasing of the driving speed. Droplet size parameters generally tended to be coarser at the higher wind speeds. This study supports the use of nozzle DG11003 as a means for controlling spray distribution.

Page 10 – 15

AbstractCurrent wastewater pre-treatment plant system handling FOG consumes high energy and time. This study aims to introduce a new FOG wastewater pre-treatment by immobilizing the FOG in a calcium alginate gel beads. Using Design-Expert software, Response surface methodology (RSM) based on face centred central composite design (FCCCD) was used to optimize two important variables; pH of FOG and concentration of sodium alginate whereas the oil entrapment efficiency (OEE) was used as a response. The mixtures of synthetic FOG wastewater and sodium alginate were dropped in calcium chloride solution in droplets form to produce gel beads. The optimum combination for having highest OEE percentage at 87.27% was found to be at pH 4.7 and 10000 ppm concentration of sodium alginate. Moreover, coating the gel beads with chitosan has reduced the FOG loss during mechanical expression from 23.73 % to 12.58 %. The gel beads were dissolved completely in phosphate buffer solution of pH 5, 8 and 9. This technique can be applied for easier FOG removal, for it has high OEE percentage and the final gel is also biodegradable.

Muhamad Norshafiq Ismail, Najihah Rafidi, Raina Jama Awale, Fathilah Ali
Page 16 – 21

AbstractConventional packaging materials are mostly produced using petroleum-based substances and its’ non-biodegradability are causing landfill problems. Therefore, researches have been done to replace the non-degradable polymer substances to degradable polymers. Polylactic acid (PLA) is a type of biodegradable polymer which is brittle but has good mechanical strength, which makes it a suitable polymer to be used as packaging materials. To improve the flexibility of PLA, PLA based polyurethanes (PUs) are produced by using PLA-diol with vegetable oil polyol as the chain extender. Palm oil polyol (PO) is a type of vegetable oil polyol which are used in various productions of PUs. In this study, PO polyol is used as soft segment to improve the flexibility of PLA whereas hexamethylene diisocyanate (HDI) and toluene diisocyanate (TDI) are used as a source of isocyanate. PLA/Palm oil polyol based polyurethanes (PLAPOPUs) are synthesized using one-shot and two steps polymerization method. Fourier Transform Infra-Red (FT-IR) spectra confirmed on the formation of urethane bond and glass transition temperature was analyzed using Differential Scanning Calorimetry (DSC). The PLAPOPU prepared using HDI through one-step method has high potential to be used in environmental friendly packaging industries.

Development of Indigenous Biofilm for Enhanced Biogas Production from Palm Oil Mill Effluent
Md Zahangir Alam, Nurfarhana Abdul Hanid
Page 1 – 8
AbstractPalm oil mill effluent (POME), high content of organic substances can be a great source for production of renewable energy i.e. biogas through microbial biodegradation. The production of biogas has widely been discovered, however, it shows a problem with the low yield of biogas produced. Thus, in order to overcome this problem, a process was used by using indigenous biofilm as a simultaneous pretreatment (hydrolysis) and biogas production. The studies on isolation, purification and screening of biofilm producing bacteria were conducted to evaluate the simultaneous pretreatment and biogas production. The results showed that the developed biofilm enhanced the biogas production with the operating pH, total suspended solid (TSS) and biofilm which were found to be 4-8, 1.5- 4.5 % and 2-4 g respectively. Based on the experiment conducted, the optimum conditions for the biogas production were at pH 8, TSS of 3.0% and biofilm used of 3 g and the highest biogas yield was 382 ml within 5 days of anaerobic digestion. Thus, anaerobic digestion of POME using indigenous biofilm to produce biogas at high yield could be an alternative and effective solution to reduce the source of pollution to the environment.

AbstractFat oil and grease (FOG) deposition into sewer pipes can block the pipes and restrict the wastewater flow causing backflows and sanitary sewer overflows (SSOs). Understanding the wastewater flow and transport of FOG particles is a key step for predicting the particles deposition and blockage formation. ANSYS FLUENT was used for simulating the flow of FOG particles and its deposition onto the sewer pipe. The multiphase Eularian-Lagrangian model with discrete Phase method (DPM) was utilized for developing the CFD model. The kinetic parameters and physical values are based on previous experimental work and literature. The CFD Eularian-DEM multiphase model has shown a good potential for simulating the wastewater flow and demonstrated the applicability of CFD to simulate and track the transport and deposition of FOG particles into the sewer pipe walls.

AbstractThe main objective of this project is to investigate the flow characteristics of the VFE2 blunt edged delta wing profiles at high angle of attack. The vortex is developed on the upper surface of delta wing and this flow physics is very complicated. The vortex flow on the sharp-edged wing develops in the Apex region. Different flow topology is observed for the blunt-edge wing. The vortex on the blunt-edged wing is not developed in the apex region but at a certain cord wise position based on angle of attack, Reynolds number and leading edge bluntness. The primary vortex moved upstream with increasing angle of attack. The problem is that this vortex will be formed up to the apex if the angle of attack is further increased. No data available at higher angle of attack of beyond ? = 30° during the VFE-2 experiments due to the constraint of the experimental work. The data from the surface pressure measurement performed at 1×10^6 and 2×10^6 is presented in this paper. The experiments were conducted at Universiti Teknologi Malaysia Low Speed Tunnel (UTM-LST) with maximum speed of 83 m/s. The data were interpreted using pressure coefficient, Cp against distance of pressure tube that based on the delta wing chord. Apart from that, tuft method was also performed to visualize the flow characteristics above the surface of delta wing at high angle of attack. The results highlight interesting flow physics above blunt-edged wing at high angle of attack. The result shows that the primary moves upstream closed the apex at high angles of attack.

Page 26 – 35

AbstractScarcity of petroleum and constant concern over environmental problems caused by diesel fuels has promoted production of biodiesel from renewable sources. Biodiesel synthesized from transesterification methods in the presence of acid or base catalyst or enzyme requires huge amount of solvent, particularly from alcohol to affirm high production yield. Inevitably, the process results in bulky waste that demands appropriate attention. In attempt to tackle the problem, ionic liquid has been identified to be the most potential substitute for conventional catalyst and solvent required in the biodiesel conversion. Ionic liquid that is widely known as ‘green chemical’ can be synthesized to meet reaction requirement by careful selection of anion and cations, with correct proportion of each to produce desired mixture. This paper reviews recent applications of ionic liquid in biodiesel production as catalyst, solvent and co-solvent. Since there are few ways in which ionic liquid can be categorized, this paper highlights classification of ionic liquids into two major groups? namely acidic and basic ionic liquid. Discussion on these tswo groups covers their dual- functions in biodiesel production which are as solvent or co-solvent and catalyst as well as the limitation of each group in the biodiesel production.

AbstractThis paper discusses the impact of the external store on the aerodynamic performance of the light aircraft model in the subsonic region. Light aircrafts are normally used to train pilots, survey, leisure and transportation. To date, there have been a lot of small aircrafts were used for a strategic purposes where an external store either external fuel storage or armament has been installed on its wing. Examples of such aircraft are KAI-KA1, A29 Super Tucano and Beechcraft AT-6. Therefore it is important to study the effect of this external store installation on the aerodynamic characteristics of a small aircraft. An available light aircraft model of UTM Low speed wind tunnel (UTM-LST) has been modified so that a generic external store can be mounted on the lower surface of the wing. Two set of experiments were carried out on the model which were; the experimental with the external store and followed by the experimental without external store as a benchmark of tested configuration. The experiments were conducted at 2 different speeds of 26 and 39 m/s that corresponding to 0.4 × 10^6 and 0.6 × 10^6 Reynolds numbers respectively. Three measurement techniques were employed on each configuration. The first measurement was the 6 component forces and moments measurement technique. The second technique was the pressure measurement on the wing while the final test was the tufts flow visualization. The result of steady balance indicates that external store has no effect on coefficient of lift at low attack angle but it shows that there was a reduction of lift coefficient by 2% at higher angle of attack. The data showed that the coefficient of drag increases by 4% when the external is installed. Suprisingly, the installation of store does not give significance effects on the pitching moment coefficient. An interesting feature is observed from surface pressure studies, the results obtained show that there is an increase in the pressure coefficient if the external is mounted on the wing at a low angle of attack, while this change does not occur at high attack angle.

AbstractThe purpose of this research project is to investigate the effects of amount of catalyst, the ratio of solid to methanol and different temperature on the biodiesel yield. Solid coconut waste and heterogeneous catalyst derived from the waste, which is calcium oxide (CaO) are used to produce biodiesel and also examine the kinetics of the reactive extraction. In this project, the heterogeneous catalyst is produced by combining solid coconut waste and egg shells and finally treating it with Al2 (SO4 )3 . Then, the mixture of wastes was calcinated under high temperature. Then, solid coconut waste in situ transesterification experiment were conducted at different amount of catalysts (2-6wt%), temperature (50-65°C) and methanol to oil ratio (6:1 – 12:1). The optimum parameters were the solid to methanol ratio, temperature and mixing speed which were at 1:10, 60 °C and 350 rpm respectively with highest yield of 47 wt%. The result proves that the biodiesel conversion increase with methanol, but the reaction did not change and decrease after achieving certain percentage of methanol.

AbstractBiogas and biofertilizer production from anaerobic digestion of local organic solid waste in Algeria is an attractive choice for greener and cleaner environment. In this paper, the study focused on the effect of co-digestion of municipal solid organic wastes (MSW) and camel dung (CD) for the quality production of biogas (methane) and bio fertilizer products. The concentration of methane production is the preeminent aim of this work. The experiment was set by feedstocks preparation where organic waste was mixed with tap water at 1:1 ratio and it allowed to digest at temperature of 40 °C. The operating hydraulic retention time (HRT) was set at 35 days. Physicochemical properties of feedstocks and constituent elements of the digestate were determined by American Public Health Association methods. The experimental study indicated that underdefined operational conditions such as constant organic loading rate (OLR) of 0.6 kg per day, hydraulic retention time (HRT) of 35 days and temperature of 40C from MSW and MSW and CD mixtures of ratio at one to one resulted in a higher methane production (57.3%) compared to monodigestion of camel dung that produced 45.6% of CH4) in a pH range between 7.0 to 8.1. The improvement has also found related to high biodegradability of the MSW, the slight ammonium concentration, the optimization of the carbon-to-nitrogen ratio (C/N 25.8:1) and to the well-balanced nutrients content of the feedstock. The digestate coming from anaerobic co-digestion has also used as bio-fertilizer and this by-product has a benefit to avoid the harmful effect in the digester system and in the surrounding environment. It is shown clearly that the MSW and CD are highly desirable substrates for anaerobic co-digestion with regards to their good biodegradability, high methane yield and good bio-fertilizer quality.

AbstractDelta wing is a triangular shape platform from a plan view. Delta wing can be applied to aircraft development as well as UAV. However, the flow around delta wing is very complicated and unresolved to date. On the upper surface of the wing, vortex is developed which need more studies to understand this flow physics. This paper discusses an experiment study of active flow control applied on the sharp-edged generic delta wing UAV. This paper focuses on the effect of rotating propeller on the vortex properties above a generic 550 swept angle model. The model has an overall length of 0.99 meter and the experiments were performed in Universiti Teknologi Malaysia Low Speed wind tunnel sized of 1.5 x 2.0 m^2. In this experiment, the experiments were conducted at a speed of 18 m/s. In order to differentiate the effect of propeller size on the vortex system, the experiment was carried out in three stages, i.e., experimental without propeller called as clean wing configuration and followed by the experiment with propeller diameter of 13”. The final experiment was the experiment with propeller diameter of 14”. During the experiments, two measurement techniques were employed; steady forces and surface pressure measurements. The experimental data highlights an impact of propeller size on the coefficients of lift, drag, and moment and vortex system of the delta-shaped UAV. The results obtained indicate that the lift is increased particularly at high angle of attack. The results also show that vortex breakdown is delayed further aft of the wing when propeller rotating at about 5000 RPM.

AbstractThis paper focused of a robust flight control system (FCS) for a small UAV. The main objective of this design is to ensure the small UAV can fly safely in severe gusty conditions. The Superaugmentation FCS consisted of Stability Augmentation System (SAS) and Command Stability Augmentation System (CSAS) was developed in UTMLST to improve the dynamic characteristics of the longitudinal stability of UAV; i.e UTM Camar. A combination of the variable stability technique along with advanced flying and handling qualities (FHQ) requirements are used to reduce the gust effect on the aircraft or UAV. The results obtained from the simulation studies showed that the superaugmented aircraft can be operated in severe gust environments than augmented aircraft. The result from here has reduced strain on the elevator activity in both extreme and calm weather conditions. Moreover, the superaugmentation FCS in the longitudinal axis meets the requirements of the level 1 handling qualities specification in flight phase.

AbstractThis paper dealt with the viscoelastic behaviour of Cellulose Oil Palm Fiber (COPF) modified 60-70 penetration grade asphalt binder for the deterioration of roads. The main objective of this study is to investigate the effect of various COPF content on the physical and rheological properties of penetration grade 60-70 asphalt binder. Laboratory tests performed comprises of viscosity, penetration, softening point, short & long term ageing and complex shear modulus (G*). The COPF was blended in 0.2, 0.4, 0.6, 0.8 and 1.0% by weight of asphalt binder including 0% as control. The COPF modified asphalt binder showed an increasing viscosity and softening point with increase of COPF content, whereas penetration decreases as the COPF increases for the binder. The complex shear modulus (G*), rutting factor (G*/sin ?) and fatigue factor (G*sin ?) show significant improvement for the modified samples compared to unmodified samples. The results indicated that the COPF modified asphalt binder has high potential to resist permanent (rutting) deformation and fatigue cracking than the unmodified sample.

AbstractThis paper summarizes a study of the aerodynamic characteristics of a curved fin rocket. The study was conducted with the use of semi-empirical method and numerical simulation. The semi-empirical method was implemented with USAF DATCOM as a reference. The ANSYS Fluent was used for the numerical simulation. The curved fin rocket configuration included a conical nose, a cylindrical body, and four curved fins attached symmetrically at the aft body of the rocket. The semiempirical method and numerical simulations were undertaken at various Mach numbers, which were 0.15, 0.4, 0.6 and 0.8 for subsonic speed. For supersonic speed, the Mach numbers were 1.2, 1.4 and 2.0. The angle of attack varied from 0? to 25? for each speed, at 5? increments. The compared results included those attained from wind tunnel testing, USAF DATCOM, numerical simulation, and those results gathered from previous researchers. According to the results, each method resulted in the same trend, and followed typical rocket aerodynamic characteristic trends.

AbstractHeat transfer enhancement of air flow using wire coiled of an isosceles triangular cross-section and twisted tape inserted in a tube have been investigated under turbulent flow regime. A simulation technique is employed to simulate the swirling flow with three different pitch ratios (P/D = 1,2, and 3). The isosceles triangle side length to tube diameter is (a/D = 0.2 and 0.4) and (a/D=0.93) of the twisted tape at a distance (s) of 2 mm from the tube wall for the both in the range of Reynolds number from 4000 to 20,000. The heat transfer enhancement represented by a Nusselt number (Nu) and friction factor (f) in turbulent flow regime is numerically investigated using CFD package (Ansys FLUENT) to investigate the physical behavior of the thermal and fluid flows under uniform heat-flux. The results show that the use of twisted tape and isosceles coiled wire lead to a considerable increase in heat transfer and pressure drop in comparison with the plane tube. The Nusselt number increases with the increase of triangle side length and twist width and with the decrease of pitch ratio. The highest overall enhancement efficiency of 126% and 150% are achieved for the isosceles triangle wire coil with a/D = 0.4 and twisted tape, respectively at P/D = 1 and Reynolds number of 20000.

AbstractWind loading is generally dominated by the separated wind flow over the roof, which resulted in pressure distribution that varies greatly in both space and time. The objective of this project is to investigate the flow visualisation of UTM new sport complex roof in wind tunnel experiment. The UTM stadium model with the scale 1:40 was used in the wind tunnel test experiment. Two different methods were employed in this research which is flow visualisation test by using smoke generator and pressure measurements on the top surface of the roof. For flow visualisation, the images were captured by using digital camera while the pressure measurement data were measured using pressure scanner. The wind tunnel test has been done successfully and the results from both wind tunnel tests were compared for validation purpose.

Wind Tunnel Study of the Effect Zigzag Tape on Aerodynamics Performance of A Wind Turbine Airfoil
Seyed Reza Jafari Gahraz, Tholudin Mat Lazim, Masoud Darbandi
Page 1 – 9
AbstractA wind tunnel study was performed on the FFA-W-3-270 airfoil, which form a segment of a 1.25 MW wind turbine blade, to examine the effect of fixed roughness height and position using a zigzag tape boundary layer trip strip. Tests were conducted at a Reynolds number of 1×106 over a wide range of angles of attack. The zigzag tape, as an artificial roughness device, not only triggers a premature transition in the flow whereby laminar flow regimes change to turbulent, but also increases the momentum thickness of the turbulent boundary layer and change the airfoil camber. The 60o zigzag tape of 0.5 mm and 1 mm height was placed on the suction side of the airfoil at different chord wise locations. The result indicated that the thicker and the closer the tape to the leading edge had more influence on the boundary layer. Due to a drop in the flow velocity at the tape, the static pressure increased. Consequently, the tripped airfoil developed a lower pressure on the suction side in comparison to the clean airfoil. The maximum lift coefficient decreased by up to 31.5% for the 1 mm tape height located at 5% of the chord and the stall occurs at a lower angle of attack.

Page 10 – 20

AbstractTwo different simulations were run using ANSYS CFX to analyze the effect of aeration on the balls and to identify the effect of different arrangement on aeration. From the first simulation, close fin ball arrangement was chosen as the best arrangement because the forces acting on the surface of fin ball and inside the fin ball in this arrangement are optimum. When the forces are too low, the scouring process will not occur which promote thicker and excessive biofilm grow which will lead to clogging while when the forces acting on bio-balls are high, detachment of biofilm from the surface will occur. From the second simulation, loose fin ball arrangement and loose cage ball arrangement were chosen as the best arrangement because there is less blue contours zone which indicates the wastewater saturated faster.

Aimi Salihah Abdul Nasir, Mohd Yusoff Mashor, Zeehaida Mohamed
Page 1 – 15
AbstractClustering is one of the most commonly used digital image segmentation technique in multifarious fields including medical image segmentation. In essence, this study proposes clustering algorithm to acquire good segmented images of Plasmodium Vivax malaria parasite species via unsupervised pixel segmentation. In this study, enhanced k-means (EKM) clustering algorithm which is an enhanced version of the conventional k-means (KM) clustering algorithm has been proposed for malaria slide image segmentation. In the proposed EKM clustering algorithm, the concept of variance and a new version of transferring process for clustered members are used to assist the assignation of data to the proper centre during the process of clustering, so that good segmented image can be generated. The satisfactory sensitivity together with the high specificity and accuracy values obtained from an average of 100 malaria images, indicates that the EKM algorithm has provided good segmentation performances as compared to k-means, fuzzy c-means and moving k-means clustering algorithms. Good segmented malaria parasite and clean segmented malaria image has been acquired using the proposed clustering algorithm. Hence, the proposed EKM clustering can be considered as an image segmentation tool for segmenting the malaria images.

AbstractTraditional heating method of pineapple puree during the production of pineapple jam can cause over degradation of quality of the fresh pineapple. Thus, the objective of this study was to determine optimum microwave-assisted processing conditions for producing pineapple jam which could reduce water activity, and meets minimum requirement for pH and total soluble solids contents of fruit jam. The experiment was designed using full-factorial experimental design, which the power and time of the microwave processing were chosen as the independent variables, while the water activity, pH and total soluble solids (TSS) content of the pineapple jam were determined as dependent variables. The microwave treatment was optimised to achieve ideal properties of pineapple jam. The optimum microwave processing of pineapple jam was obtained at 800 Watts of power for 8 minutes. The usage of domestic microwave oven for the pineapple jam production also results in acceptable pineapple jam with 62% of consumers’ preference compared to conventional fruit jam sold in the marketplace.

AbstractThe potential of bacterial biomass for the biosorption of heavy metals has investigated extensively. However, the bacterial species exhibited different affinities toward the heavy metals ions based on their differences in cell wall characteristics, structure and physiological status (living or dead cells). In this study, the potential of living and dead cells of Staphylococcus xylosus 222W for removal nickel ions from aqueous solution as a function for physiological status, nickel and biomass concentrations, time, pH and temperature was investigated. The pre-treatment of bacterial cells was performed by the heating at 100 ºC for 15 min. The removal experiments were conducted in the lab scale. The results revealed that the dead cells exhibited more efficiency in removing nickel ions than living cells at all investigated concentrations (2 to 10 mM). The biosorption efficiency (E %) increased with increasing in biomass cells to limit concentrations (0.1 to 1 g dry wt L-1). The maximum removal of nickel was 81.41 vs. 77.10 % by living and dead cells, respectively achieved after 9 and 10 hrs of the incubation period, respectively. The acidic conditions decrease the efficiency of metal removal, while the optimal removal was recorded at pH 8 for both biomass (living and dead cells). The maximum uptake capacity of S. xylosus 222W (living and dead cells) was recorded at 37oC, the percentage removed being 75.90 vs. 84.92 %, respectively. It can be concluded that S. xylosus 222W exhibited high potential and affinity to remove of nickel ions from aqueous solution.

AbstractThe polyvinylidene fluoride (PVDF) membrane has been a popular material in membrane separation process. In this work, molecular dynamic (MD) simulation was done on the PVDF membrane with 100 wt% water, 100 wt% 1,3-dialkylimidazolium bromide ([C2bim]Br) ionic liquid (IL), 100 wt% heptane and 50 wt% IL at GROningen MAchine for Chemical Simulations (GROMACS). The results were evaluated based on potential energy, root mean square deviation (RMSD), root mean square fluctuation (RMSF), radial distribution function (RDF) and contact angle. The stability and interaction of PVDF were evaluated. Results reveal that PVDF has a stronger interaction to [C2bim]+ cation compared to water, heptane and bromine anion. At high concentration of IL, potential energy and RMSD were lower. RDF reveals that [C2bim]+ cation is dominant at short distance (less than 1 nm), indicating that strong interaction of cation with PVDF. Contact angle analysis proved that PVDF membrane is a hydrophobic and oleophilic membrane. IL has a good wettability characteristic on PVDF at high concentration and vice versa. Molecular dynamics (MD) simulation is an effective tool whose results can be used as reference prior to further experimental approach.

Page 46 – 56

AbstractMobil Composition of Matter-41 (MCM-41) is recognized as a potential filler to enhance permeability of mixed matrix membrane (MMM). However, the required loading for available micron-sized MCM-41 was considerably high in order to achieve desired separation performance. In this work, reduced-size MCM-41 was synthesized to minimize filler loading, improve surface modification and enhance polymer-filler compatibility during membrane fabrication. The effect of reaction condition, stirring rate and type of post-synthesis washing solution used on particle diameter of resultant MCM-41 were investigated. It was found that MCM-41 produced at room temperature condition yielded particles with smaller diameter, higher specific surface area and enhanced mesopore structure. Increase of stirring rate up to 500 rpm during synthesis also reduced the particle diameter. In addition, replacing water with methanol as the post-synthesis washing solution to remove bromide ions from the precipitate was able to further reduce the particle size by inhibiting polycondensation reaction. It was also noticed that particle diameter of MCM-41 is optimized with 15 hours of calcination.

AbstractIn this research work, aqueous hybrid solvents were prepared at different concentrations of 1-butyl-3-methylimidazolium acetate, [bmim][Ac] as ionic liquids (ILs) and N-methyldiethanolamine (MDEA) for the capturing of carbon dioxide (CO2 ). The concentration of MDEA was kept constant at 30 wt% in every hybrid solvent investigated. The solubility of CO2 in the hybrid solvent was investigated by varying the concentration of [bmim][Ac] in the aqueous hybrid solvent as 10 wt% and 20 wt%. For comparison, the solubility experiment was also conducted for pure aqueous MDEA solvent. Addition of [bmim][Ac] in the hybrid solvent reasonably enhanced the solubility of CO2 as compared to its solubility in pure aqueous MDEA solvent. The loading capacity of hybrid solvent was also improved significantly with hybrid solvents. Further increasing the concentration of [bmim][Ac] from 10 wt% to 20 wt% has demonstrated a decrease in the solubility of CO2 into the hybrid solvent. The effect of pressure on loading capacity and rate of absorption was also investigated by increasing the pressure from 10 bar to 20 bar. Both loading capacity and rate of absorption increased with increasing pressure. Promising results were achieved using hybrid solvents for capturing of CO2.

AbstractBee bread is the pollen that has been stored in the cells of the honeycomb with various enzymes and honey, which undergoes lactic acid fermentation, while propolis is a resinous material collected by bees from buds of the plants and transform it using bee enzymes. The main objective of this research was to investigate the antioxidant and antimicrobial activity of the stingless bee bread and propolis extracted using 70% ethanol and n-hexane. The antioxidant activity of sample extracts were determined by 2,2,-di-phenyl-2-picryl-hydrazyl (DPPH), 2,2-azinobis-(3-ethylbenzothiazoline-6- sulphonic acid) (ABTS) and Ferric Reducing Antioxidant Power (FRAP) assays while for the antimicrobial activity, the sample extracts were analyzed using disc diffusion and broth macrodilution assay. For the DPPH and ABTS assays, the results showed that ethanolic extract of bee bread showed the highest percentage of free radical scavenging as compared to other samples with the values of 93.60 ± 0.03% and 97.95±0.01%, respectively. However, FRAP value for both hexanic extract samples, bee bread and propolis have the values of 0.85±0.0 mM FE/g and 0.87±0.00 mM FE/g respectively which were higher than ethanolic extract samples, 2.41±0.02 mM FE/g (bee bread) and 6.64±0.04 mM FE/g (propolis). For disc diffusion assay, the results showed that ethanolic extract of bee bread and propolis as well as hexanic extract of propolis were able to inhibit all tested bacteria in varying diameter of the inhibition zone. Broth macrodilution assay showed minimum inhibition zone (MIC) ranging from <6.67 to 33.33 µL/mL. As the conclusion, all of the samples in this study displayed antioxidant and antimicrobial effect but there are different in the degree of antioxidant and antimicrobial activity exhibited between each of the samples.

AbstractIn current study, the ability of the ethanolic extract of Alstonia angustifolia in scavenging free radicals was assessed by using 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and hydrogen peroxide (H2O2 ) radical scavenging assay. The results suggested that the ethanolic extract of A. angustifolia leaves has a notable antioxidant activity. In FRAP assay, it showed that the extract have higher total antioxidant activity with FRAP value is 1868.33 µM/g Fe (ii) dry mass ± 0.15 than the control, quercetin with FRAP value is 1336.9 µM/g Fe (II) dry mass ± 0.12 and ascorbic acid with FRAP value is 1720 µM/g Fe (II) dry mass ± 0.02. For DPPH assay, the IC50 value of the extract is 384.77 while the IC50 value of standards of ascorbic acid and quercetin are 18.07 µg/ml and 39.60 µg/ml, respectively. For H2O2 scavenging assay, the IC50 value for the extract was discovered to be 186.77 µg/ml compared to standard ascorbic acid 466.56 µg/ml. Thus, the study suggests that A. angustifolia ethanolic leaf extract has a good origin of natural antioxidants and might be beneficial in impeding the oxidative stress progression thus averting diseases that related to free radicals.

The Influence of Fluctuating Light Condition on Photosynthetic Acclimation in Arabidopsis Thaliana
Furzani Pa’ee, Giles Johnson
Page 87 – 95

AbstractPhotoacclimation is a process by which photosynthetic capacity is regulated in response to environmental adjustments in terms of light regime. Photoacclimation is essential in determining the photosynthetic capacity to optimize light use and to avoid potentially damaging effects. Previous work in our laboratory has identified a gene, gpt2 (At1g61800) that is essential for plants to acclimate to an increase and decrease of growth irradiance, separately. To investigate the photoacclimation ability towards fluctuating natural light condition in Arabidopsis thaliana, photosynthetic capacity was measured in plants of the accession Wassileskija (WS) and in plants lacking expression of the gene At1g61800 (WS-gpt2). The experiment was carried out over a time span from early Autumn to early Spring season in 2010-2011 and 2011- 2012. The seedlings were grown in an unheated greenhouse in Manchester, UK without supplementary lighting. Gas exchange measurements, chlorophyll fluorescence analysis and chlorophyll content estimation were performed on WS and WS-gpt2 and it showed that both sets of plants could acclimate to fluctuating natural light condition. Therefore, it is suggested that the mechanisms of acclimation in a separate growth light condition is mechanistically distinct than the mechanism under fluctuating natural light condition.

Page 96 – 102

AbstractIn this research work, piperazine (PZ) was used to activate the performance of aqueous N-methyldiethanolamine (MDEA) solvent for the capturing of CO2 . The solubility experiments were conducted at a temperature and pressure ranges of 303.15 to 333.15 K, and 2 to 50 bar, respectively. The solubility of CO2 was investigated in terms of CO2 loading capacity as the ratio between the quantities of moles of CO2 absorbed to the total amount of moles of solvent used. It was observed that CO2 loading has increased with increasing the partial pressure of CO2 while increasing the temperature has a negative effect as the loading capacity has decreased with increase in system’s temperature. The CO2 loading capacity of the solvent investigated in this research work has demonstrated better performance as compared to conventionally used alkanolamines solvents.

Aerodynamics of a Trapped Vortex Combustor: A Comparative Assessment of RANS Based CFD Models
Hesham Khalil, Khalid Saqr, Yehia Eldrainy, Walid Abdelghaffar
Page 1 – 19
AbstractTrapped vortex combustion, TVC, has shown promising results in terms of wide stability range and low pressure drop. However, previous experimental and numerical studies, which were limited to DNS, have provided only global performance assessments. Also, high computational cost limitations of DNS motivated the need for evaluating other lower cost turbulent models. Consequently, three RANS turbulence models were assessed in the present work; RKE, SST-KW, and RSM, using 2D numerical computations. In addition, the effect of inlet flow Re on cavity flow physics and stability was explored for more detailed physical insight. Ansys Fluent 12 has been used in the computations with the steady state compressible pressure based solver. RSM was found to have the least prediction error percentage against experimental data with maximum value of 12.1% for all cases studied compared with 23.9 % demonstrated by the SST-KW which was the least accurate model. Increasing inlet flow Re by order of magnitude had no apparent effect on the main flow structure for the same cavity size. However, the 300 % Re increase from 9229 to 27687 has led to 10 times increase in turbulence levels and 3 times increase in recirculation zone strength which confirms the high stability range of these combustors. Finally, multiple vortex structures, either behind the forebody for smaller cavity sizes of H/Df < 0.6 or behind the afterbody for larger cavity sizes H/Df > 1, were noticed to be the main reason behind increased pressure drop from 0.8 to 1.1%. This study was conducted as a ground base for future TVC analysis.

AbstractOne of the most significant current discussions in material properties is the chemical treatment effect on the proposed materials. In this paper, the effects of NaOH and ?APS silane treatments on the characteristics and thermal analysis of Polypropylene (PP) /Recycled Acrylonitrile Butadiene (NBRr) / Banana Skin Powder (BSP) was studied. The heated two roll mill was used to melt, mix the compositors at a temperature of 180?C to produce six different fibre loading (70/30/5, 70/30/10, 70/30/15, 70/30/20, 70/30/25 and 70/30/30w/w). The effects of NaOH and ?-APS silane treatment on PP/NBRr/BSP composites were analyzed by Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). Based on the results, the ?-APS silane treated PP/NBRr/BSP composites has higher improvement on mechanical properties compared to the NaOH treated PP/NBRr/BSP composites, followed by the weakest mechanical properties of untreated PP/NBRr/BSP composites. These were due to good compatibility and stronger interaction between Si-O-Si moieties with the surface of fiber for ?-APS silane treated BSP. Both ?-APS silane and NaOH treated PP/NBRr/BSP composites have the same improvement of thermal properties and better than untreated PP/NBRr/BSP composites. DSC results also showed ?-APS silane treated composite has a higher crystalline portion than untreated PP/NBRr/BSP composites. The results presented here may facilitate improvements in the material properties, especially Polypropylene (PP) /Recycle Acrylonitrile Butadiene Rubber (NBRr) /Banana Skin Powder (Bsp) Composites with NaOH and ?-Aps Silane Treatment.

AbstractPitaya seed oil, extracted from red pitaya seeds, was utilized as a major antioxidant source in soap formulation for skin application. Bentonite (grey clay powder) with various beneficial properties also was incorporated in the formulation to enhance the positive effect toward skin’s structure. The influence of the main compositions of soap formulation containing different fatty acid and oils (cocoa butter, virgin coconut oil, olive oil, palm oil) on the hardness of the soap that undergoes saponification process was investigated by employing D-optimal mixture experimental design. Analysis of variance (ANOVA) was carried out and the polynomial regression for prepared soap hardness in terms of the six design factors was developed by utilizing the experimental data. Results revealed that the best soap formulation included 9.027% A, 29.098% B, 19.588% C, 9.223% D, 23.860% E and 9.204% F. The results showed that the hardness of the soap was greatly affected by the different in the level of fatty acid and oils in the formulation. Depending on the appropriate level of those six variables, the production of moisturizing clay soap containing pitaya seed extract with the most desirable properties which is much better than those of commercial ones is possible.

Page 67 – 80

AbstractThe present study investigates the combined effects of slip and inclination on peristaltic transport of Casson fluid in an elastic tube with porous walls. The modeled governing equations are solved analytically by considering the long wavelength and small Reynolds number approximations. A parametric analysis has been presented to study the effects of Darcy number, the angle of inclination, elastic parameters, velocity slip, yield stress, amplitude ratio, inlet and outlet radius on volumetric flow rate. The study reveals that an increase in the angle of inclination has a proportional increase in the pressure rise. Also, an increase in the porosity has a significant reduction in the pressure rise.

AbstractUnderstanding of flow pattern behaviour inside the aorta contributes significantly in diseases treatment artificial design. Objective of present study is to simulate the blood flow in patient specific aorta using open source computational fluid dynamics (CFD) platform OpenFOAM. The real geometry was obtained from real male Malaysian patient. There are not much data available in literature incorporate real geometry of aorta due to complex geometry. The validation is done against existing experimental result of the 90 degree curve tube model. It was shown that our method is able to capture complex flow in the curve tube like secondary and separation flow that responsible for development of wall shear stress at the tube wall. These flow physics could have similarity in aorta blood flow. Finally, we apply our method with anatomy human aorta with pulsatile inlet condition. Further comparison is made with unstructured boundary fitted mesh. The final result shows that the detailed flow physics can be captured in an aorta.

AbstractResponse surface methodology (RSM) has been fully utilized in this study to model and optimize the extraction conditions for maximum antioxidant compounds activity from Curcuma zedoaria leaves. This work was carried out based on three factor/5 level of central composite rotatable design (CCRD) and three independent variables, namely extraction temperature (60-80? C), processing time (80-120min) and solvent concentration (70-90 v/v %). The experimental data was subjected to total antioxidant activity measured by the 1, 1-diphenyl-2-picrylhdrazyl (DPPH)-radical scavenging, ?-carotene bleaching (BCB) inhibition as well as ferric ion reducing antioxidant power (FRAP). By using the desirability functions, the optimal conditions were found to be at temperature 75 ? C, 92 min and (90:10 v/v%) ethanol concentration for the highest total antioxidants values for DPPH, BCB and FRAP were 85.76%, 81.35 % and 5.08 mM Fe2+ g/DW respectively, which closely agreed with the predicted values of 87.59%, 82.29%, 5.25 mM Fe2+ g/DW respectively.

Page 104 – 111

AbstractThe quality of agrochemical spraying depends on speed of the sprayer and cross wind. Dynamic spray mechanism was designed and installed in the wind tunnel for simulating the effect of speed of the sprayer and cross wind combinations on droplet spectra classifications (DSC). It is able to generate two dimensional spraying (2D) at uniform sprayer speeds under wind tunnel conditions. Droplet spectra classifications were studied using water sensitive papers (WSPs). The effect of cross wind and sprayer speed on dynamic spray was analysed and compared with reference spraying. The result of the tests showed that there were differences in the DSC when speed of the sprayer and wind speed increased. This spray mechanism was suitable for the assessment of the dynamic spray.

AbstractPorous media combustion has been key point of interest for researchers from past couple of decades due its numerous advantages, such as remarkable low emission levels without compromising thermal efficiency. In this present work, dual layered micro burner was built with predefined thickness of reaction and preheat layer. Reaction layer was made up of alumina (discrete type) while preheat layer porcelain (foam type) material. Burner was successfully built to undergo both surface and submerged flames. A concept of equivalences ratio was enabled since its premixed combustion with natural air as one of the inlet along with butane. Trials were not just restricted at stoichiometric ratio but also carried out up to ultra-lean region. Additionally, numerical simulation was performed using commercially available computational fluid dynamics package so that porous media combustion phenomenon can be better analyzed and predicted. Finally, Thermal efficiency was calculated at critical equivalence ratios and emission parameters such as NOx and CO was continuously monitored which were under controlled limits.

AbstractThe effect of polypropylene maleic anhydride (PPMAH) as a compatibilizer in polypropylene (PP)/ sugarcane bagasse (SCB) composite were studied. The composite were prepared through melt mixing at the 180 o C for 7 minutes using 15 rpm rotor speed using heated two roll mill. The mixing was moulded into 1 mm thin sheet by using the hot press machine with temperature at the 180 o C for 10 minutes. Then, the sheet was cut into dumbbell shape for further analysis. The specimens were analysed for thermal and tensile properties. The thermal and tensile strength was found to be decreased with increasing of filler content. However, tensile strength and Young’s modules of the PP/SCB/PPMAH composite were found to increase, while the elongation at break showed the opposite trend as compared to the control composite.

Page 149 – 157

AbstractEntrance effect and formation of the vortex structure play a vital role in understanding the flow physics at the channel entry especially in oscillatory flow inside the channel between thermoacoustic stack plates. The aims of the current study are to investigate the effect of flow frequency on the structure of the vortex shedding at the end of the stack plates and also the effect of the vortex formation at the end of the plates associated with “entrance effect”. The methods used are CFD simulation with ANSYS FLUENT as a solver. The flow was solved using laminar model and two-equation Shear-Stress Transport (SST) k-? turbulence model. The “entrance effect” and vortex flow phenomena has been studied for two drive ratios, DR (defined as ratio of maximum pressure amplitude to mean pressure) which are 0.65% and 1.0% at two frequencies of 13.1 Hz and 23.1 Hz. The results shows that at higher frequency, the entrance length becomes shorter. This can be emphasized that flow frequency plays a significant role as it affected the entrance length and vortex formation and structure of the flow.

Page 1 – 11
AbstractThis study investigated the effect of yaw angle on the aerodynamic performance of hatchback vehicle model fitted with a spoiler featuring a configuration combining the wing and strip spoiler designs. To date, majority of the tests performed on spoilers were done in a straight-ahead driving condition. However, the effect of spoiler is most demanded during cornering for stability reason. A RANS-based Computational Fluid Dynamics (CFD) method was used to simulate the flow. Validation of the method was carried out by comparing the numerically obtained results with the experimental data. The findings show that both the drag coefficient, Cd, and lift coefficient, Cl had increased when the vehicle was subjected to higher yaw angle. The wing part of the spoiler did performed in favour of reducing the Cl , but its contribution to the overall Cl was only about 4.28%. The main body parts contributed to the decrease in Cd and Cl are the front and underbody, respectively.

Page 12 – 23

AbstractA proper ventilation system is necessary for isolating and reducing airborne particles in a hospital operating room. Most healthcare uses a downward unidirectional (laminar) flow in the area of the operating table to give a sterile environment to the patient. However, the unidirectional downward airflow can easily be deviated due to a buoyancy force induced by heated surfaces such as a person’s and medical lamp’s surfaces. Therefore, the goal of this study is to investigate the effects of lamps and human body surface temperatures on particles distribution in the vicinity of the operating table inside an operating room. A simplified computational fluid dynamics (CFD) model of the operating room was developed using commercial software. An RNG k-epsilon turbulent flow model was used to simulate the airflow while a discrete phase model (DPM) was used to simulate the movement of the airborne particle of size 5 ?m. Results of CFD simulations show that when the surgical lamp and staff surface temperatures were prescribed at 45°C and 37°C, respectively, a more significant amount of particles appear to be on the floor of the adjacent area of the operating table head section. On average, the particle concentration in the vicinity of the operating table increases by 16%.

Page 24 – 35

AbstractAerodynamic valuation plays an imperative role in understanding the characteristic response of a helicopter with respect to the airflow. Understanding the airflow around the helicopter is much more challenging compared to the flow field around a fixedwing aircraft. The situation becomes even more convoluted when environmental turbulences are introduced in the scene such as the gust wind loading, which is one of the most catastrophic commotions. Refereeing to the obvious, this study took out this daunting task to actually generate artificial gust and study its effects on the main rotor airflow physiognomies of a coaxially configured subscale helicopter. Quantitative data congregated by measuring the rotor induced airspeed underneath the rotor blades, which is quintessentially the lift/thrust, have revealed intriguing outcomes. The implementations of various strengths of active robust gust have caused the helicopter to experience half-hearted rolling motion pared with the incremental loss of altitude during hover. For forward flight, this investigation reveals the helicopter distinctively lost cruising speed along with the altitude as well when subjected to the gust. During hover and forward flight conditions, results depict that lift is decreased about 33% when subjected to the gust. These findings are alleged to be valuable for future research and development in the rotorcraft industry.

Page 36 – 46

AbstractWater Distribution Networks (WDN’s) are used for providing water to residential areas. These networks have various junctions and interconnections spanning hundreds of kilometers. In the current work CFD simulation is carried out initially to determine the location of flow separation and recirculation inside a T-junction. Furthermore a parametric study is carried out to reduce this separation by implementing Vortex Generators (VG’s). VG’s are most commonly used in aircrafts to reduce the flow separation. A parametric analysis is carried out considering three VG configurations and later an upgrade is carried out. Simulations are carried out using ANSYS Fluent. The results show that, implementation of VG’s effectively reduces the reverse flow and thus provides a solution to existing problem in Water Distribution Networks (WDN).

Page 47 – 54

AbstractThe wake region of a circular cylinder with and without shroud was experimentally investigated using smoke-wire flow visualization. The shrouds were made of screen cylinders, constructed from various screen meshes. The shroud-to-cylinder diameter ratio, D/d were 1.56 and 2.0 and the flow Reynolds number based on the cylinder diameter, Red was approximately 1000. The vortex formation process was investigated and the formation length, Lf was estimated from the flow visualization. The effect of a new dimensionless parameter, ?.dw/d (where ? is the screen porosity and dw is the mesh wire diameter) on the vortex formation length was also examined. Results showed that the formation length was greater at gap ratio of 2.0 than that at 1.6, with smaller wake width observed in the former in comparison to that in the latter. The formation length also increased with increased non-dimensional parameter ?.dw/d after its critical value was reached.

AbstractUnderstanding the thermodynamics’ fundamental are important for the advance of energy and environmental technologies. The study aims to derive an expression of the average pressure on the piston surface, ps p in an adiabatic piston-cylinder system during an irreversible process with finite piston speed using the kinetic molecular theory. Expressions for the average pressure on the piston surface, ps p are derived from the change of momentum and change of energy. The MaxwellBoltzmann distribution is used to estimate the gas molecule velocities. The piston surface pressure obtained from the change of momentum is 37.18% lower than that obtained by the previous study. The piston surface pressure obtained from the change of energy is 26.94% lower than that obtained by the previous study.

AbstractExfoliation of oxide scales is known to be associated with the stress and strain developed during the oxide growth. This paper presents a simple procedure to estimate the oxide scale growths and critical failure strains in boiler austenitic tubes over a period of time. In this work, a classical heat flow formula and the relationship between the Larson Miller Parameter (LMP) and the scale thickness were utilized. An approach called Advance Oxide Scale Failure Diagram (A-OSFD) was adopted. The oxide scale failure diagram would provide a general guidance to the power plant engineers to estimate the critical strains.The technique may be used as a supplementary condition monitoring tool for oxide scale growths and to evaluate the critical failure strains.

AbstractInterest in the use of heat pipes in solar applications is increasing due to their role in improving the heat transfer performance of solar collectors. In order to effectively utilise heat pipes, their performance under various operating conditions and inclination angles need to be investigated. In this work, numerical and experimental studies were carried out to investigate the effects of heat input and inclination angle on the wall temperature distributions and thermal resistance of thermosyphon heat pipe. A Computational Fluid Dynamics (CFD) model was developed using ANSYS Fluent to simulate the flow and mass transfer using volume of fluid (VOF) approach together with user – defined function (UDF) to simulate the phase change processes at various inclination angles. Experiments were carried out to validate the CFD model at heat inputs of 81.69W and 101.55W with temperature distribution results showing good agreement of ±4.2% average deviation. Also the predicted thermal resistance at different inclination angles showed good agreement with the experimental ones with maximum deviation of ±5.7%. Results showed that as the heat input increases, the heat pipe wall temperature increases and the thermal resistance decreases. Experimental and numerical results showed that increasing the inclination angle will improve the thermosyphon heat pipe performance to reach its maximum value at 90o, but this effect decreases as the heat input increases.

AbstractComputational Fluid Dynamics (CFD) simulation inside an Operation Theatre (OT), considering real world conditions such as temperature and airflow movement in the OT environment is carried out. Simulation is carried out using Phoenics software to predict the flow velocity and temperature distribution inside the OT. Parametric study is done to determine the most suitable inlet and outlet configuration. Only one out of the six cases provided the required cooling and reduced recirculation. Results indicated that the entire ceiling inlet with eight outlets was the best case, for further studies to be carried out considering contaminants.

Page 123 – 130

AbstractSolid-liquid (S-L) interfaces is widely used in lubrication and coating systems, in which the heat transport is the main problem for the system. In the recent years, lubrication and coating systems have been investigated up to the molecular scale to solve the problem of heat transport due to wear and friction. In molecular scale, the characteristics of heat transport are different from the conventional one. Therefore, the purpose of this study is to specifically investigate the characteristics of heat transport in the molecular scale at the S-L interfaces. The prime concern in this numerical investigation is the surface structure of solid and the type of liquid molecules. The characteristics of heat transport at the S-L interfaces are evaluated based on the temperature jump (TJ) and thermal boundary resistance (TBR) at the interfaces. It is found that the different TJs and TBRs can be observed for variation of the surface structures and the length of liquid molecules. The obtained results show that the surface structures and length of liquid molecules significantly affect the characteristics of heat transport at S-L interfaces.

Page 140 – 148

AbstractFlow past two interlocking squares cylinder is largely unexplored in the field of bluff body wake. This paper aims to investigate the wake region behind this body at Re=150. The study was carried out numerically using ANSYS-Fluent solver with viscous-laminar model. The results obtained were compared with that of a square cylinder. It was observed that the flow separation was delayed at the downstream sharp corner of the two interlocking squares cylinder, resulting in an early interaction between the shear layers behind its wake. The maximum vorticity magnitude was slightly higher (of about 6%), indicating a higher intensity of vortices in the two interlocking squares wake than that of the square cylinder wake, consistent with the spectral analysis. A larger lift fluctuation with higher amplitude was also observed in the former in comparison to that in the latter.

Simulation Study of Combustion Characteristics of Diesel-Ethanol-Palm Oil Methyl Ester Blends in Diesel Engine
Norhidayah Mat Taib, Mohd Radzi Abu Mansor, Wan Mohd Faizal Wan Mahmood, Nik Rosli Abdullah
Page 149 – 156

AbstractDiesel-ethanol-palm methyl ester (PME) blends are believed to be able to improve the combustion characteristics since diesel, ethanol, and PME have different fuel characteristics. This paper is aimed to study the combustion characteristics of pure diesel and diesel-ethanol-PME blends with different compositions through simulation works and to estimate the best fuel composition that can be used in real engine applications. A simulation work was conducted using seven different diesel-ethanolPME blends for a combustion based on a compression ignition Yanmar TF90 engine parameter by using a CONVERGE CFD software. Seven diesel-ethanol-PME blends (10 vol% to 40 vol%) PME were mixed in ethanol together with 50 vol% diesel fuel operated at 1600 RPM. High PME percentage increased the heat release rate (HRR). However, due to non-uniform chemical energy release from the reaction, the blends of 25 vol% PME with 25 vol% ethanol blends released the highest HRR. A high percentage of ethanol reduced the temperature and increased the heat release. From the cumulative heat release, ignition delay occurred for blends that had more than 15 vol% ethanol. In conclusion, blending ethanol and PME in diesel increased the combustion heat release rate to have better engine efficiency. However, the blend that contained more than 35 vol% ethanol was not suitable to be used in direct injection compressed ignition engine without any modification since the temperature and HRR of the blends is very low.

Wasu Suksuwan, Makatar Wae-hayee, Maizirwan Mel
Page 157 – 166

AbstractIn this work, the effect of single and double air inlets on swirling flow in a reactor of fluidized bed gasifier was studied numerically. The reactor diameter (D) was 20 cm, and the reactor length was 7.5D. The geometry of the reactor bottom was conical. In order to generate swirling flow in the reactor, the air inlet pipe with inner diameter of 46.8 mm was assembled tangentially to the bottom of the reactor. The comparison of the effect of single and double air inlets were studied based on the same mass flow rate. A 3-D numerical model of the reactor was created using a commercial software of ANSYS Ver.15.0 (Fluent). The results showed that swirling flow at the bottom of the reactor for the case of double inlets was more uniform than that of single inlets. Therefore, double air inlets were applied to design and fabricate a swirling fluidized bed gasifier.

Effect Of Using Various Longitudinal Fin Number In Finned Channel Heat Exchangers On Heat Flow Characteristics
Wadhah Hussein Al Doori
Page 1 – 10
AbstractThis paper presents the air-side overall heat transfer coefficient and pressure drop characteristics for finned channel with various longitudinal fins number. The computational fluid dynamics analysis with ANSYS Fluent software was applied for the analysis of the heat transfer. Numerical simulation was performed for the different longitudinal fins number of (4, 8 and 12), at air flow speeds of 3 m/s to 7 m/s and validated with available correlations. The numerical simulations results, with respect to the pressure drop and exchanged heat were verified by the correlations available in the literature and compared to the simulation results for plain channel. The results indicated that maximum enhancement in Nusselt number of 265%, 221% and 153% credited to the finned channel with 12, 8, and 4 fins respectively. Moreover, the increase in fins number led to significant improvement for both Nusselt number and Euler number.

Page 11 - 24

AbstractAn experimental study by using flush-mounted conductance probe sensors has been carried out in an air-water horizontal annular flow. The experiment was arranged in a 26-mm diameter pipe with superficial gas velocity of 10 to 40 m/s and superficial liquid velocity of 0.025 to 0.4 m/s. The probe detects the liquid film thickness at 7 circumferential positions from the bottom part to the top of the pipe and the liquid holdup is determined from the average of the circumferential liquid film thickness. A range of liquid holdup form 0.022 to 0.21 is resulted from the experiment. A decrease of liquid holdup is resulted with the increase superficial gas velocity and decrease of superficial liquid velocity. Conversely, the liquid holdup increases with the decrease of the gas velocity and the increase of liquid velocity. Examination of the experimental data by using 7 previous available correlations results in a reasonably good agreement.

AbstractAn investigation of mixed convection flow in a boundary layer saturated by a nanofluid and lodged in a porous medium with the existence of Soret and Dufour numbers, suction and thermal radiation is numerically studied. By employed a similarity transformation technique, the governing set of ordinary differential equations has been conducted from a non-linear partial differential equations system, where we apply a Runge-Kutta-Fehlberg method in order to numerically solved the final equations for a group of variety metallic and nonmetallic nanoparticles in a water base fluid consisting of copper (Cu), aluminium oxide (Al2O3) and titanium dioxide (TiO2). Numerous values of presented parameters such as thermal radiation coefficient, suction parameters, as well as Dufour and Soret numbers are graphically presented and discussed on the dimensionless velocity, temperature and concentration distributions profiles.

AbstractAerosols are particles in the air floating the atmospheric. They can have a huge impact about climate and human health point of view. The impact on the physical environment may be of importance as they are the capable to both scattering and absorbing incident irradiance. In this work, aerosol optical depth (AOD) of 500 nm for Nakhon-pathom, Chiang-mai and Songkhla of Thailand Penang and Sarawak in Malaysia Singapore for Singapore in the case daily average aerosol optical depth. The investigation was based on the solar spectrum of sun-photometers measured at six positions: Chiang Mai meteorological station (18.77°N 98.97°E) Nakhon Pathom(13.82°N 100.04°E) Songkhla meteorological station (7.18°N 100.60°E) Penang (5.36°N 100.04°E) Sarawak (1.49°N 110.35°E) and Singapore (1.30°N 103.78°E).When comparing AOD data from these sites for 7-years.The results show tolerances in case of the root mean square error (RMSE) between the daily retrieval of aerosol optical depth from Aqua satellite and that from the AERONET ground measurement were from the ranged of 5.34% to 18.73%. As the number of aerosol optical depth monitoring station in Thailand, Malaysia and Singapore are still very limited, it is recommended that number of the stations be increased in order to obtain more spatial coverage of information on aerosol optical depth.

The Aerodynamics of a Formula One Car Front Cascade Wing during Cornering
Ahmed T. Raheem, Azwan Sapit, Akmal Nizam Mohammed
Page 53 - 60

AbstractThe design for the aerodynamics of front wing based on cornering angle of a Formula-One car plays an important role on the car’s performance. The cascade elements above the main front wing is enhanced with new and the deep winglets that manage the airflow for the rest of the car. The front wing cascades are attached with end plates at the extremities of the front wing to reduce turbulence. However, when the car turns, the airflow behaviour on these cascades wings changes significantly. This paper presents the aerodynamic characteristics resulting from the cornering forces subjected on Formula One styled cascade wings. The study attempts to predict the down-force and drag-force acting on the front wing under the effect of airflow change in this area. In order to investigate the airflow behaviour, computational fluid dynamics (specifically the ANSYS software) was used to simulate selected cases with specific surface definitions and boundary conditions defined in a 3D domain. It can be observed that with the increase in the car’s yaw angle during turning, the down force and the drag force decrease in an inversely proportional manner.

Page 61 - 68

AbstractThe aerodynamic drag on trucks can be reduced by use of active and passive techniques. In this work a passive method of using a cab-extender that is attached to the rear of the tractor is attempted. This cab-extender will help in reducing the drag force that act on the truck by minimizing the gap between the tractor and trailer. In this study, a tractor-trailer model was fabricated and tested in a low speed wind tunnel for its aerodynamics characteristics and the effect of cab-extender was also studied. Later Solid Works CFD package was used to study numerically the effect of this cab-extender on the aerodynamics of the truck and the results were validated against the experimental results. Finally using CFD approach the best angle of the cab-extender was reported for minimum drag.

AbstractDirect imaging technique is always used to obtain correlation of flame height or any other parameter of the visible portions of the flame. This is one of the important methods used in the combustion community to determine the characteristic of flame. Recently, the imaging technique has been developed and enhanced to provide more accurate data. However the utilization of the technology, such as the used of laser-based technique and acquiring sensor, increased the complexity of the process and also increased the amount of cost practically. This paper presents the results of an acoustic excitation towards a Liquid petroleum gaseous flame by using the direct visualizing technique. The direct visualizing technique is used to acquire the flame image and the images will be analyzed by using image analysis software. Results show the flame length at the flame core decreases when the amount of acoustic gradually increases. The effect of excitation towards the flame core is being investigated due to its significant influence toward the overall flame characteristic.

Page 75 - 81

AbstractThe atomization of internal-mixing twin-fluid atomizers is highly dependent on the internal geometry of the mixing chamber. Many studies have been conducted on the air entrance geometry influencing the air-fuel mixing. This paper aims to determine the effects of a multi-circular jet (MCJ) plate on the spray formation of twin-fluid atomizers. Plates 1, 2 and 3 with different open area ratios were used in the experiments. A swirler was used for comparison. The spray images were captured at different equivalence ratios using a direct photography method. ImageJ software was used to analyse the breakup length of spray formation. Results corroborate that, as the open area ratio of an MCJ plate increases, the break-up length decreases. The opening area for primary air entrance into the mixing chamber contributes to the air-fuel mixing, thereby affecting the spray performance of twin-fluid atomizers.

Page 82 - 94

AbstractNumerical investigations of forced turbulent convective flow and heat transfer in a symmetry semicircle-corrugated channel with SiO2-water nanofluid as the working fluid are carried out in this investigation. The algebraic continuity, momentum, and energy equations were solved by means of a finite volume method (FVM). The top and bottom walls of the corrugated channel are heated at constant heat flux boundary conditions. The effects of geometrical parameters including corrugation height and pitch on the thermal and hydraulic characteristics are studied. The corrugated channel with four different corrugated heights of 0.0, 1.5, 2.0 and 2.5 mm with a different corrugation longitudinal pitch of 15.0, 25.0 and 35.0 mm are tested. This investigation covers Reynolds number and nanoparticles volume fraction in the range of 10000–30,000 and 0-8%, respectively. The results show that the average Nusselt number enhances with increase in Reynolds number and with the height of the corrugated channel, but this enhancement accompanied by increases in pressure drop. In addition, as the corrugation pitch decreases, the average Nusselt number increases and the pressure drop decreases. The numerical results indicate that the corrugated height of 2.5 mm with a corrugation longitudinal pitch of 15.0 mm are the optimum parameters and have shown significant improvement in heat transfer.

AbstractAir-Conditioning system plays vital role in Indoor Air Quality. Low humidity in atmosphere cost crucial consequence to human skin and nasal passages. Installing ultrasonic humidifier to air conditioning system is one of the options to make up lost humidity. An experimental HVAC rig is combined with ultrasonic humidifier to humidify the system by using a piccolo tube. This paper presents experimental study of humidity profile in an experimental rig at different air velocity and piccolo holes diameter. Experiment results show that, under fixed inlet air velocity and mist flow rate, relative humidity (RH) increased with piccolo holes diameter. RH of 12mm holes diameter piccolo tube is 7.4% higher than 5 mm holes diameter piccolo tube for 3ms-1 air velocity. Similarly, under fixed piccolo holes diameter and mist flow rate, RH is decreased with increasing air velocity. RH of 5ms-1 velocity is 13.4% lower than 1ms-1 velocity for RH change. Rate of humidity added to the HVAC system by ultrasonic humidifier also increased with respect to holes diameter size and air velocity. 3ms-1 and 12 mm piccolo holes diameter shows highest gradient humidity mixing rate.

New Development of the Metal Volume Thermal Expansion
Fazrul Mohd Nor, Abd Rahman Tamuri, Abd Khamim Ismail
Page 106 - 110

AbstractVolume thermal expansion measurement of the solid is one of the most challenging issue in material industry especially when the solid is in big size. The existing instruments such as dilatometer has a limitation to determine the volume thermal expansion of material. Therefore, a new and precise system has been proposed to determine the volume thermal expansion. In this study, several samples such as gold and tungsten were used to determine its volume thermal expansion by using custom made hydrostatic weighing system (HWS) where the experimental results show that the HWS can determine the volume thermal expansion. Volume thermal expansion value for gold rod and tungsten rod are 1.5×10-4 °C-1 and 7.7×10-5 °C-1 respectively. The expanded uncertainty obtained using HWS was 0.0003 °C-1. To assure the quality of the HWS, inter-instrument comparison between HWS and dilatometer was performed. The results of the comparison show that the En ? 1 indicates the performance of the HWS is acceptable. Thus, this study will demonstrate on how the volume thermal expansion of the material is precisely and accurately measured using HWS. Furthermore, it is cheaper than dilatometer with reasonable accuracy and it was traceable to SI unit.

Micro-bubble Drag Reduction by Multi Discrete Hole Plate on Self Propelled Barge Ship Model
Yanuar, Kurniawan T. Waskito, Gunawan, Bagus D. Candra, Aufa Y. Perdana
Page 111 - 121

AbstractShip resistance is one of the main problems dealing with ship performance and fuel consumption. Microbubble Drag Reduction System (MBDRS) which is applied by injecting air onto the bottom of the hull is a promising technique of active method which it has been developing in various ways. The particular applications of these methods in relatively bottom displacement flat hull (self-propelled barge) are significant to support other available data. Moreover, the complex relation of the ship speeds, injection rates, and hull form take into account in this paper and need to be studied further in which show the optimization between the injection rate and ship speed at the particular cases as well as the bubble and air layer effects account for these results. The injected air bubbles to the bottom of the ships are supposed to modify the turbulent boundary layer properties in which can reduce the hull friction. The objective of this research is to identify the effect of microbubble injection on a self-propelled barge (SPB) model with main dimensions: L = 2000 mm, B = 521.6 mm and T = 52.5 mm. The optimum injector location and injection ratio at each ship speed can be obtained by conducting a towing tank test microbubble injection of self-propelled barge ship model at the after bow (0.35L) and after midship (-0.025L) sections at Fn range 0.11 – 0.31 and injection ratio 0.2 – 0.6. Bubble size distribution for each case describes the phenomena of the results obtained. There is the pilling-up effect of the microbubble during the propagation covering the bottom surface hull and so does in this experimental results visualization. Sometimes the size seems bigger in the after side due to the interaction between different injection rate and different model speed. The size of the microbubble in micro size while come out from the porous media as shown in the scale bar of bubble visualization. The test results show that after bow injection area gives the lowest drag reduction compares to the after midship injection with different optimum injection ratio for each case.

AbstractSynthetic jet impingement cooling has been identified to be an advanced cooling technique in a variety of applications such as turbine blade cooling, paper drying, and electronic cooling. The high heat removal capabilities with a simple construction of the device, demonstrate the advantage of synthetic jet compared to other methods. In the present work, the 3D numerical simulation using computational fluid dynamics (CFD) is carried out to predict the heat transfer performance of synthetic jet produced by speaker actuator with the diffuser-shape orifice. Numerical predictions are made for an orifice diameter of 6 mm with several opening angles. The excitation frequency of the speaker diaphragm is fixed at 100 Hz. Three vibration amplitude are used to investigate the effect of the different velocity of synthetic jet. The results showed that the opening angle of 90o is better than 45o and the heat transfer enhancement using a diffuser shaped orifice is more significant at a higher vibration amplitude. Also, the increment of vibration amplitude more than 0.6mm may not increase the cooling performance of synthetic jet.

Discrete Tonal Noise of NACA0015 Airfoil at Low Reynolds Number
Amelda Dianne Andan, Duck-Joo Lee
Page 129 - 145

AbstractThis paper is a pilot study of the effect of external forcing and passive control on the generation of airfoil whistle noise. Interaction between instability travelling inside laminar boundary layer with the airfoil trailing edge produces discrete tonal noise. This phenomenon commonly found at low-to-moderate Reynolds numbers. The characteristics and behavior of tonal emissions at low Reynolds number differs from that at higher Reynolds number. Therefore, the purpose of this work is to study the discrete tonal noise generated by laminar boundary layer instability at low Reynolds number as well as at a variation of angle of attack. Experimental testing on NACA0015 was done in the anechoic wind tunnel to measure the sound spectrum at Reynolds number of Re~104 and angle of attack of 0°???5°. This work is intended to provide additional information to the tonal behavior of NACA series airfoil. Flow separation without reattachment occurs on the suction side within the selected Reynolds number and angle of attack. No tonal sound was found if fs falls below 40dB. At low Reynolds number, airfoil discrete tone consists of high intensity fs accompanied by more pronounced fn as freestream velocity increases. Airfoil tonal noise gradually decreases as angle of attack increases from ?=0^° before disappearing beyond ?=5°. Moreover, previously proposed empirical models to predict fs were found to have limitation in predicting tonal frequency at low Reynolds number at a variation of angle of attack. In addition, general observation shows fn has a velocity dependency of ~U0.8 while f_s is prone to exhibit ladder structure behavior with velocity dependency of ~U1.3.

AbstractA Diesel-CNG dual fuel vehicle is a modified diesel vehicle that is capable of running two fuels. It may have future potential in Malaysia because of its promising cleaner exhaust emissions and lower fuel cost. Thus, a study on its prospective implementation was executed based on three objectives. First is to evaluate potential consumer acceptance of Diesel-CNG Dual Fuel application in Malaysia. Second is to analyse the public awareness on Diesel-CNG Dual Fuel vehicles, and third is to estimate economic gains of using the Diesel-CNG Dual Fuel vehicle. This study focused on consumers that are using light and medium duty diesel vehicles in Malaysia. A quantitative method was applied to obtain the data in the study. A survey was conducted and the set of questionnaires were circulated through two methods, personal interviews and an online response medium. All data from the survey was analysed based on the sampling size obtained from Transport Statistics Malaysia. The survey result shows a total of 63% respondents are interested in installing the DDF system to their vehicle in order to lower their fuel cost and help in conserving the environment. In addition, 70% respondents stated that the main cause that preventing them from installing the DDF system is lack of NGV stations and shop services. Level of awareness on Diesel-CNG Dual Fuel vehicle in Malaysia is still low with only 40% of the respondents know the existence of this system. However, they have shown that their awareness on the current environmental issues is very high.

Page 185 - 193

AbstractA semicircular grooved cavity is designed for controlling the base pressure and hence the base drag in case of a backward facing step. This paper presents the effect of the continuous grooved cavity to control the base pressure for various compressible subsonic flow to minimize the base drag. Grooved cavity of 1.5 mm radius at 45o along pitch circular diameter of 23 mm in the base region is employed as passive controller. The test is conducted for Mach 0.6, 0.7, 0.8 and 0.9. The square nozzle of side 10 mm with an angle of incidence as 150 on all four side from which the flow suddenly expands to a square duct of side 25 mm acts as backward facing step model. The experimental investigation is carried out for three ducts of length equivalent to 4, 6 and 8 times width. The results of this investigation provide grooved cavity at 45o as a very effective passive control mechanism to regulate the base flows, further at higher Mach numbers it may be associated with minor effect on the main flow field.

Page 194 - 203

AbstractAlthough the demand for rockets and missiles has increased exponentially but the problems of the gas dynamics related to these vehicles remains to be a challenge. The main problem is high-pressure associated with the shock wave in front and low-pressure recirculation bubble attached behind the vehicle at the blunt base. This barrier of wave drag due to the shock waves and the drag due to the bubble leads to a huge amount of the fuel consumption and high fluctuations in the flow field of the enlarged duct. This paper focuses mainly on the base drag and experimentally investigated the effect of the passive control in the form of the threaded spikes for bluff bodies as the base flow controller. Two threaded spikes of length 40 mm opposite to each other and attached to a control plate of diameter 80 mm and thickness 1 mm are at pitch circular diameter of 23 mm and slot of 10 mm X 10 mm at the center, placed between the nozzle and the duct to act as the passive controller. The Mach numbers considered for the investigation in the subsonic regime were 0.6, 0.7 and in the transonic regime were 0.8, 0.9 for the enlarged duct cross-sectional area of 625 mm2 and the exit area of the nozzle considered was 100 mm2. The lengths of the enlarged duct were 100 mm, 150 mm and 200 mm. The passive control and regulating the base pressure by threaded spikes were found very efficient without any adverse effect on the flow field of the enlarged duct.

Page 204 - 212

AbstractRecently there has been increasing concern regarding environmental impacts due to carbon dioxide (CO2) emissions caused by waste collection activities, apart from the active industrialization efforts. In this context, evaluation of environmental impacts in Waste Collection Vehicle Routing Problem (WCVRP) is highlighted. As such, this paper investigated CO2 emissions based on solution derived from a prior study of the benchmark waste collection problem. With that, the fuel-based and distance-based methods had been employed to estimate CO2 emissions. Both methods were selected due to their applicability and suitability in the estimation of CO2 for WCVRP. The results showed that the distance-based method produced less value of CO2 emissions (approximately 7.1 % decrement) and lower value of fuel consumption (approximately 1.77 % of fuel saving), when compared to the fuel-based method. Besides, it is important to note that the reduction of CO2 emitted depends on distance travelled, fuel consumption, and emission factors. Thus, reduction in travelled distances and fuel usage do aid in mitigating vehicle emissions.

AbstractThe purpose of this work is to show the effect of external parameters: albedo and wind speed) on a solar collector inclined plane. The method used consists in cutting the collector into fictitious slices (05 meshes) of length ?x in the direction of the flow of the heat transfer fluid and writing the balance sheets of the exchanges which intervene at the levels of the 06 nodes: from the outside of the glass, the inside of the glass, the absorber, in the peddler fluid as well as the inside and the outside of the insulation. It is convenient for this to use the analogies that exist between the transfer of heat and electricity, the results obtained are the temperatures at the nodes.

Page 223 - 233

AbstractA numerical analysis of laminar natural convection in a horizontal annulus between an internal heated plane and an external cold half-elliptical was investigated using approximation of Boussinesq. Both internal and external walls are maintained at the constant temperature and air is the working fluid. Numerical solutions are obtained using a commercial computational fluid dynamics package, FLUENT, using the finite volume method. Effects of the Rayleigh number, Rat, on the Nusselt number, Nu, as well as velocity and temperature fields are investigated for the range of Rat from 1.0 103 to 5.0 105. The results show that for a small thermal Rayleigh number, the heat transfer within the annulus is essentially controlled by the conduction process. As the thermal Rayleigh number increases (Rat ? 104), the role of convection becomes predominant. Also the heat transfer rate increases. The aim of this study is to observe the effects of thermal Rayleigh numberon the structure of the flow and the distribution of the temperature.

AbstractA nonlinear three-dimensional thermal process was studied experimentally and numerically. The present study aims to investigate the distribution of temperature in the joint of aluminum AA2024-T3 plates throughout the friction stirred butt. The experiments were conducted at a constant tool tilted angle of 3 under various rotational speeds (690, 1130, 2000 rpm) and feed rates (20, 32, 45 mm/min). The highest temperature of 860 K was obtained at the experimental condition of 2000 rpm, 20 mm/min, 20 dwell times, and 3 tilt angle. This value was less than the melting point temperature of Al 2024 alloy (911 K). The comparison between the numerical and experimental results of temperature distribution showed a good agreement. The deviation between the theoretical and experimental results for the maximum and minimum rotational speed and feed rate was (7, 10 %) and (5, 12 %), respectively.

The solution of chosen system gives a distribution of flow velocity profile through the studied section, and from the velocity values, others parameters can be deduced such as: the maximal velocity, Reynolds number, the volume of considered flow, the friction force to exert on the wall, as well as the shear stress. The validation was made with a comparison between obtained solutions and results given by analytical solutions with reference to cases of a simple section such as the circular section. Developed code and analysis can be used, as helpful tool, in many technological and engineering applications related to construction and installation of conduits, and in particular when users are interested in modifications of conduits section. In this study, special attention has been given to effects of section form on the distribution of flow velocity profile, to have results and necessary data according to the geometry of the selected conduits which permit to determinate the performances of desired system.

Experimental Correlation for Flow-boiling Heat Transfer in a Micro-gap Evaporator with Internal Micro-fins
Shugata Ahmed, Ahmad Faris Ismail, Erwin Sulaeman, Muhammad Hasibul Hasan
Page 1 – 8
AbstractMicro-gap evaporators are prospective candidates for cooling of micro-electronic devices. Heat transfer with phase change in a micro-gap heat sink is efficient for high heat flux applications. Micro-fins induce turbulence escalating two-phase heat transfer rate in the micro-gap evaporator. However, no correlation has been developed so far for fin-induced pseudo-turbulence and heat transfer rate in micro-gap heat sink. The scope of this paper is to develop a correlation for dimensionless heat transfer rate in a micro-finned micro-gap heat sink for refrigerant 134a. The correlation signifies the effect of evaporation rate on thermal resistance of the heat sink. For this purpose, a micro-gap evaporator was fabricated with a gap height adjusted to accommodate 48 rectangular shaped micro-fins. A heater at the bottom of the heat sink provides variable heat flux. The evaporator is installed in a test section along with a heat pump in the outer circuit. The frequency of the compressor is varied using a variable frequency drive. A pre-heater is used to vary inlet temperature of refrigerant. In the developed correlation, dimensionless heat flux is function of calculated vapor Reynolds number and Biot number. Results calculated from the correlation show maximum 2.7% error in comparison to actual results.

Page 9 - 20

AbstractThe thermal performances of a R410A filled thermosyphon subjected to low heat flux from 1882 W/m2 to 4423 W/m2 and evaporator wall temperatures between 20 °C and 50 °C with fill ratios 1.00 and 0.75 and at different inclinations from 45°, 68° and 90° were investigated. The axial temperature distribution of the thermosyphon was found to be uniform for all temperatures difference of evaporator at all power inputs. The performance of the thermosyphon which is determined from the heat transfer capability of the thermosyphon was found to be dependent of inclination angle and fill ratio. Experimental results show that heat transfer coefficient increases as the heat input increase while thermal resistance decreases exponentially with increasing input power. Increase in fill ratio and inclination angle at various heat input contributed to a better thermosyphon performance, at where heat transfer was highest at fill ratio 1.00 and inclination angle of 68°. In addition experimental and application measured readings have a percentage error less than 10%.

AbstractAluminium alloy are widely used in the design of structural parts in the automotive and aircraft components due to their good mechanical properties. Numerous applications are related to high strain rate deformation and adiabatic heating require further intention. The strain-rate effects and temperature effects have not been well studied experimentally. Therefore, the effect of temperature and strain rate on the mechanical behaviour of aluminium alloys (AA6061) is critically examined in this work. The specimen was tested in the longitudinal direction from quasi-static to high strain rates (0.08, 0.8 and 8 mm/min) while temperature was varied from room to elevated temperatures (24, 140, 200 and 250ºC). From the results, it show that the flow stress increase with increasing the strain rate and decrease when increasing temperature. Which means, increasing strain rate and temperature affect the saturation stress of the materials.

Page 27 - 36

AbstractA pipe is a fundamental component of the geothermal power plants to drain the water vapor from the inside of the earth. Structural durability is the main focus of geothermal pipe which is affected by the thermal stress caused by internal pressure and fluid temperature. In the present study, the stress intensity factor for mode I was investigated under variations of fluid temperature and crack size. A commercial finite element analysis (FEA) was used to find the highly stressed regions in the geothermal pipe by using solid-fluid interaction model and calculate the stress intensity factors. Variations used in this study are a fluid temperature in pipes of 80oC, 115oC, and 150oC and surface crack size of 1 mm, 3 mm, and 5 mm. This study used ASTM A106-B steel material which is geothermal pipe standard. The result showed that the fluid temperature and crack size in the pipe installation affects the stress intensity factor. The stress intensity factor increased with increasing the fluid temperature in the pipe and crack size. Furthermore, the pipe installation with 5mm crack size and fluid temperature in pipes 115oC and 150oC has stress intensity factor value that exceeds the fracture toughness value of the material. This condition will lead the crack to propagate along the pipe.

AbstractThis study proposes the parameter study and multi-objective optimization of a vapor compression heat pump system using environmentally friendly refrigerant, R1224yd(Z). The effect of three design parameters including refrigerant mass flow rate, evaporation temperature, and condensation temperature on compressor work, cooling load in the evaporator, heat rejected by the condenser, and exergy of the system are investigated through parameter studies. A multi-objective optimization was then performed. Exergy efficiency and exergoenvironmental value are the objectives of this optimization scenario. The purpose of the optimization is to obtain the optimum value of three design parameters in terms of exergy and environmental point of views so that the heat pump system has maximum exergy efficiency and minimum effect to the environment. The result showed that the system will be in the optimum condition at Te = 287.98 K, Tc= 315.56 K and refrigerant mass flow rate = 0.0321 kg/s with the exergy efficiency of 38.48% and exergoenvironmental value of 200.98 mPts/h.

Sze Qi Chan, Fazlina Aman, Syahira Mansur
Page 57 - 69

AbstractThe paper discusses a sensitivity analysis on a water-based bionanofluid having nanoparticles and living microorganisms flows over a moving surface. Mathematical model is constructed on the basis of Buongiorno model and a thermal convective boundary condition is taken over to replace the conventional fixed surface temperature. Numerical shooting technique is to follow closely behind the similarity transformation to solve the system of governing equations. The output parameters of interest are believed to be contingent on the governing input parameters. Obviously, the skin friction coefficient as well as the surface shear stress will only affected by the velocity ratio parameter; while the inclusion of thermal convective boundary conditions influenced the temperature profile, confined movement of the nanoparticles and living microorganisms. Focus on the response of local density of motile microorganisms to the variation of input parameters, an experimental scheme integrated with sensitivity analysis is designed. As highlighted, the local density of motile microorganisms is more sensitive to the bioconvection Péclet number rather than other governing parameters. The findings believed to offer preliminary guideline for further lab-based experiments.

Page 78 - 86

AbstractPresent paper elaborates solution of partial differential equations (PDE) of two dimensional steady state heat conduction by using a bi quadratic triangular Galerkin’s finite element method (QGFEM). The steady state heat distribution is modeled by a two-dimensional Laplace partial differential equations. A six- point triangular planar finite element model is developed for the QGFEM based on quadratic basis functions on the Cartesian coordinate system where physical domain is meshed by structured grid. The elemental stiffness matrix is formulated by using a direct integration scheme along the trilateral domain area without the necessity to use the Jacobian matrix. Validation is conducted to an analytical solution of a rectangular plate having mixed, asymmetric boundary conditions. Comparisons of the present QGFEM results and the exact solution show promising results. The convergence of the method is presented by checking the error analysis for various number of elements used for the simulation.

Page 95 - 101

AbstractOil and gas exploration in Semau, one of some islands in East Nusa Tenggara of Indonesia has caused by eruption of gas and mud. This incident is considered a disaster because it harms the people around who lost their property and fields. The mud slurry characteristics by passive control method of highly concentrated mud eruption containing solid particles have been investigated. Actually, when the particles that flowed not sufficiently high, it caused by low velocity of mud slurry. This natural phenomenon can illustrate the reality of how the behaviour of the phenomenon of sludge flow deposition occurs. Spiral pipe with twist grooves are constant on the axis pipe and slurry that also rotates when it is flowed. By the behaviour of the swirl flow, particles are allowed to flow at low speeds. The purpose of this study is to examine the characteristic flow of mud slurry that is flowed in the three lobe spiral pipe. The shear rate and shear stress are obtained by measuring the pressure drop and the volumetric flow rate in circular pipe. By the experiment, the power law exponent in this study ranged from 0.72 to 1 for liquid and solid particles of 20%, 30%, and 45% by weight of concentration. The particle diameter of the test in this study is 1-5 ?m and density is 2.7 x 103(kg/m3). The degree of homogeneous distributed suspension of liquid and solid particles for horizontal axis of the pipe were compared with circular pipe and spiral pipe in laminar and turbulent flow. Through this research, P/Di = 7 spiral pipes proved to reduce friction resistance higher than circular pipe. The higher drag reduction happened for 25.58 % with the generalize Reynolds number 5 x 103. The value obtained shows that the spiral pipe impacts the drag reduction to the mud slurry.

AbstractThis article presents the impact of abuse discharge condition on the battery cell surface temperature. The abuse discharge condition is when the battery is discharge down to 10% State of Charge (SOC). To determine the temperature evolution of the battery cell surface, a series of experiments is conducted. Three battery cells in a battery pack are discharged at 1C, 3C, and 5C discharge rate with a constant cooling air velocity of 2 m/s. The battery is discharge from 100% SOC down to 10% SOC to simulate the abuse discharge condition. Experimental results show that discharging the battery at SOC lower than 20% contributes to a radical increase of cell temperature at all battery cell locations impacted by a sudden increase of internal resistance’s value in this region.

Page 112 - 123

AbstractTensile properties and physical properties of fireproof Inconel 718 have been investigated after under undergoing a high-temperature flame fire test of 1100 ± 80?C with a heat flux of 36 ± 2 kW/m2 according to the ISO 2685 standard using a methylacetylene-propadiene propane (MAPP) gas burner. The main aim of this study is to understand the physical properties of the different binders and different sintering cycles of the Inconel 718 after a tensile test. The alloys were exposed to a flame temperature for 15 minutes after which they are allowed to cool at ambient temperature before the tensile test. All the Inconel 718 samples of different binders undergo a scanning electron microscope (SEM) micrograph after the tensile test and show different characteristics according to the binders and sintering cycles. The result obtained on the comparison of the different binders and sintering cycles shows that the third sintering cycle is more ductile than the other two cycles with the highest ductility observed on the 68/32-6 stearic acid binder, while the most brittle alloy is the 66/34-5 stearic acid binder in the fourth sintering cycle. From the SEM micrograph, it is clearly observed that an Inconel 718 of the 66/34-12 palm stearin binder has smoother surface grain with huge hollows and low density, therefore the alloy is more porous and penetrable and more prone to break than the other alloys under study. Conclusively, the third sintering cycle proved to be the most effective Inconel 718 for this study due to the excellent properties exhibited by the alloy for both binders.

Page 124 – 132
AbstractA series of new cholinium-based ionic liquids (ILs) was synthesized by using simple neutralization reaction. The synthesized ILs were choline phenylacetate, choline ricinoleate and choline trichloroacetate. Result obtained from FT-IR, 1H and 13C NMR, mass spectrometry, thermogravimetric and differential scanning calorimetry confirmed the formation of these cholinium-based ILs. These ILs were then tested for their anti-microbial properties towards seven types of bacteria which consist of three Gram-positive bacteria, Bacillus subtilis (B29), Staphylococcus aureus (S276), Staphylococcus epidermidis (S273), two Gram-negative bacteria, Pseudomonas aeruginosa (ATCC 15442) and Escherichia coli (E266) and two types of yeasts, Candida albicans (9002) and Candida tropicalis (A3). Interestingly, all of the cholinium ILs possess excellent antimicrobial activity as good as the standard, Streptomycin. The most significant antimicrobial activity was observed in choline phenylacetate against all seven types of bacteria tested in this study.

Page 133 - 141

AbstractA study of quantum dots-in-well infrared photodetectors (QDIPs) yields results useful for the creation of a two-colour QDIP. Quantum dot infrared photodetectors (QDIPs) have been shown to be a key technology in mid and long wavelength infrared detection due to their potential for normal incidence operation and low dark current. This study investigates infrared detectors based on intersubband transitions in a novel InAs/In0.15 Ga0.85 As/GaAs quantum dots-in-well (DWELL) heterostructure. In the DWELL structure, the InAs quantum dots are placed in an In0.15 Ga0.85 As well, which in turn is placed in GaAs quantum well with In0.1Ga0.9As barrier. The optical properties of the sample have been studied by the means of photoluminescence using fourier transform infrared spectroscopy. Spectrally tuneable response with bias and long wave IR response at 6.2?m and 7.5?m has been observed.

Evaluating the GMAW Joint with a Constant Heat Input

Page 142 - 149

AbstractThe most important aspect of the overall welding process is determining the welding parameters which are usually described in a form of Welding Procedure Specification – WPS. WPS is written by an experienced welding engineer. Following the WPS in the welding application is expected to provide optimum joint properties for a certain applied load and environment conditions. One of the most important parameter which is frequently prescribed in WPS is heat input. This paper is presented based on the curiosity to prove the equal heat input does not always produce identical joint. An actual experiment method of constant heat input welding was implemented by varying welding speed with adjusted electric current. The tensile test then is carried out to the weldments to analyze the effect of the varied welding parameters. Finite Element Method (FEM) was used to acuminate the analysis. Using the FEM the temperature history of desired position can be obtained. This temperature history is an important additional data to give a technical reason why the tensile strength is as what exhibited by data from tensile test. The tensile test shows that with higher electric current the higher tensile strength is obtained. From temperature history, which is emulated by FEM, the higher electric current originates faster cooling rate. This faster cooling rate produces harder joint and in turn provides higher tensile strength which is confirmed by the tensile test.

Page 150 - 164

AbstractThis paper discussed the effect of sample mixture preparation on the performance of Thermochromic Liquid Crystals (TLCs) in terms of maximum intensity, hue sensitivity and aging effect. Three type of TLC mixtures were prepared; (A) solely TLC aqueous slurry solution, (B) TLC aqueous slurry solution and aqueous binder with a ratio of mixing of 3:1, and (C) TLC aqueous slurry solution, an aqueous binder, and tap water with a ratio of 5:1:6. The result obtained shows that sample A gives a higher maximum intensity values compared to the others. Furthermore, sample A with only TLC solution has better hue sensitivity at the red color region. As it goes to the green color region, the sample C, has the highest sensitivity due to the anchoring force present among the molecules. In term of resistance to aging effect, sample B and C that been mixed with other composition are having better resistance towards the effect as it been provided with extra shield resulted from the microencapsulation with aqueous binder. To sum up the result, sample mixing method has significant effect on the performance of the TLCs. The usage of solely of TLC without another additional compound may give higher maximum intensity and sensitivity on certain region but it will have low resistance towards the aging effect.

AbstractThis paper presents an experimental and theoretical study of using the ground and water geothermal affects to the cool the buildings. This done by helical heat exchanger submerged under the well water. Where the tests were conducted in the city of Tikrit / Iraq in hot and dry climate for the period from May to June. The results showed that the use of the water heat exchanger reduces the temperature of the air inside the test room 10 – 15 oC less than the ambient temperature. In addition, the results showed an improvement in relative humidity of 15-20% and a decrease in cooling loads by 50%. The temperature of the well water has great effects on the temperature of the supply air from the heat exchanger. Also, the temperature at the depth of 3 m under the ground will be constant and reached to 21 – 22 oC. The solar radiation has more effect on the ground’s temperature at depth 0.25 m. Results showed a significant agreement between theoretical and experimental results.

AbstractSolid oxide fuel cells (SOFCs) directly convert chemical energy into electrical power with minimal carbon emission. However, maintaining consistently stable electrical power generation can be challenging for SOFCs that operate at high temperatures ranging from 600?C?1000?C. Furthermore, the rigid SOFC assembly stack is prone to the development of thermal stress that leads to mechanical deformation, which subsequently shortens the lifetime of the SOFC system. Hence, identifying a uniform temperature gradient across the stack can minimize the thermal stress distribution across the stack and help prolong the service life of an SOFC system. This paper discusses the source of generated heat, the heat transfer mechanism, and their relation with the temperature gradient and thermal stress distribution.

AbstractAluminium alloy are widely used in the design of structural parts in the automotive and aircraft components due to their good mechanical properties. Numerous applications are related to high strain rate deformation and adiabatic heating require further intention. The strain-rate effects and temperature effects have not been well studied experimentally. Therefore, the effect of temperature and strain rate on the mechanical behaviour of aluminium alloys (AA6061) is critically examined in this work. The specimen was tested in the longitudinal direction from quasi-static to high strain rates (0.08, 0.8 and 8 mm/min) while temperature was varied from room to elevated temperatures (24, 140, 200 and 250ºC). From the results, it show that the flow stress increase with increasing the strain rate and decrease when increasing temperature. Which means, increasing strain rate and temperature affect the saturation stress of the materials.

Page 191 - 203

AbstractThe aim of this study is to estimate mathematical relationships of vital fuel properties that are heating value, density, pour point, cloud point, flash point and viscosity of waste cooking oil/diesel blends and biodiesel fuels. The origin of both waste cooking oil (WCO) and biodiesel (BD) are from palm oil to keep the uniformity of this study. To find the fuel properties, experimentation methods are carried out to acquire data for each blend sample. The samples of blends prepared are ranging from 10% to 100% for both waste cooking oil and biodiesel blend with diesel respectively. From the data of fuel properties obtained, graphs of each fuel property against percentage of blends are plotted. Using Microsoft Excel, mathematical equation for each fuel property for WCO/Diesel and BD/Diesel blends are produced with their respective coefficient of determination denoted as R². The results have shown that the properties of the fuel mainly have polynomial relationships. The equations produced are important because fuel properties are prerequisite as input data for research regarding engine combustion diagnostically and in prediction. From the results obtained, it was also determined that BD blends are of better fuel characteristics than WCO blends because of the positive effects of transesterification.

Page 204 - 220

AbstractThe recycled concentric tube heat exchanger was designed with the principle of recycled heat transfer technique over a short concentric tube, which successfully constrained the heat transfer area of the conventionally long arranged or floating tubes to a reduced size in terms of cycles/minute. Validation was then carried out by experiment to ascertain its viability and the new concept was named cycle pasteurization following its success. The total head loss of both water and milk side of the heat exchanger were so negligible at 0.00002. The rate of heat, area, length, no of cycles, log mean temperature difference and effectiveness of the heat transfer were analyzed with respect to the pasteurizer and has exhibited very good characteristics which have kept the milk composition and it organoleptic properties safe for consumption. The most critical of the thermodynamic properties were coefficient of heat transfer of 1.411 and 4.2319 W/m2 k and fouling factor of 0.7087 and 0.2363m2 ?/W at the beginning and end of tube heat transfer respectively, which are within the limits of pasteurization theory to keep the milk nutritive values safe for consumption. This valuable equipment with 2 litres capacity for home use and the concept of cycle pasteurization has effectiveness of 0.59 representing 98.3% efficiency of the system. Indeed, the pasteurizer will complement the existing conventional batch and flash pasteurization methods where arrangement of plates and floating long concentric pipes are used which is characterized with the challenge of micro-scale pasteurization.

MHD Rotating Flow Through a Porous Medium with Heat and Mass Transfer
Bommanna Lavanya
Page 221 - 231

AbstractIn this paper, we have considered heat and mass transfer on the unsteady two dimensional MHD flow through porous medium under the influence of uniform transverse magnetic field in a rotating parallel plate channel. A mathematical model is developed for unsteady state situations using slip conditions. Analytical expressions for the velocity, temperature and concentration profiles, wall shear stress, rates of heat and mass transfer and volumetric flow rate have been obtained and computationally discussed with respect to the non-dimensional parameters. We concluded that the velocity reduces with increasing Hartmann number M and enhances with permeability parameter K. Blood visco-elasticity lesser flow velocity significantly. The resultant velocity enhance with increasing Gr, Gc and slip parameter. At any particular location as the thermal radiation increases, both heat transfer rate and temperature are reduced to an appreciable extent. However, the velocity is not significantly affected by thermal radiation.

AbstractThis paper presents a numerical study to investigate the effect of subcooling with liquid-suction heat exchanger (LSHX) on the performance of air conditioning system using R22, R410A, R290 and R32 as refrigerants. In the near future, R290 and R32 refrigerants are projected to replace R22 and R410A as working fluids in the residential air conditioning. In this study, four parameters, i.e., the refrigerating effect, compressor work, COP and discharge temperature were investigated. In the numerical modelling, the evaporating and condensing temperatures were assumed constant at 5oC and 40oC, respectively. The results showed that the COP improvements increased with the increase in the subcooling. R32 and R290 had the lowest and the highest COP improvement when subcooling was applied, i.e., 3.3% and 5.3% for subcooling of 5K and 6.2% and 10.2% for subcooling of 10K, respectively. Due to low global warming potential and almost identical refrigerant properties as compared to R22, system with LSHX and R290 has huge commercial potential as a replacement for conventional system in the future.

AbstractThe objective of this study is to investigate the effects of pressed palm conditions on acceleration of palm drying rate and CPO (Crude Palm Oil) quality. Three pressed palm conditions were dried in hot-air tray dryer, namely (1) conventional palm, (2) slightly-broken palm and (3) fully-broken palm. The velocity of hot air was fixed at 0.7 m/s with hot air temperature of 80 and 100oC. The hot air was blowing through the drying chamber approximately 30 hours as imitate the same condition with conventional drying in factory. The result shows that the drying rate of broken palm is faster than the case of conventional palm. Especially, the drying rate of fully-broken palm is the fastest. This expectation can minimize energy consumption in drying process. For CPO quality, however, FFA of CPO for the case of the broken palm was higher than the case of conventional palm which degrade the CPO quality. The suggestion using this method can be developed and applied in oil palm milling process which is acceptable for getting low CPO quality as oil palm for blending in animal food.

AbstractCrash box is known as passive safety devices used to reduce collision damage effect. This study aims to develop two-segment crash box design by utilizing rubber as inter-segment holder. Al 6063-T5 is used as crash box material with Butyl Rubber connection. The design parameter is the location of the segment connections: 1/4, 1/3, and 1/2 of the total length of the crash box. Energy absorption, and deformation patterns is observed as response variables. From the simulation result, it can be obtained that crash box with 1/3 segment connection has the highest energy absorption (1.326 kJ). The results showed that crushing force efficiency (CFE) of the crash box with 1/3 segment connection was highest, followed 1/4 segment connection and 1/2 segment connection, respectively. The deformation pattern of three models is diamond mode. The deformation pattern of the crash box with 1/3 segment connection is more stable due to more symmetrical deformation pattern.

Specific Energy Consumption and Drying Efficiency Analysis of Commercial Mixed-Flow Batch Type Seed Drying System
Mohamad Zaharan Azmi, Ibni Hajar Rukunudin, Hirun Azaman Ismail, Aimi Athirah Aznan
Page 39 - 50

AbstractIn Malaysia, numerous extensive researches to gauge the performance and energy requisite of paddy dryers and milling quality of rice were conducted by past researchers. These studies gave valuable insights into paddy drying and its effects under Malaysian climate and promoted further research opportunities, especially in engineering and studies on energy. However, the study of commercial grain dryer’s performance for paddy seed drying still lacks in Malaysia. The absence of fundamental information, such as the drying rate, drying efficiency and energy requisite in regard to paddy seeds drying leads to ill-informed judgements and poor decision-making which can be detrimental, especially in regards to the national policy on food security. This study was therefore undertaken to evaluate the performance efficiency of a commercial, mixed-flow, batch type seed dryer at Loji Pemprosesan Benih Padi Sah (A) at Telok Chengai, Kedah. Two types of performance indices were studied, namely drying efficiency (DE) and specific energy consumption (SEC). DE examines the drying process more analytically whilst SEC draws an overall conclusion and provides a better comparison among other commercial dryer performances. It can be inferred that, to analyze the performance of a certain dryer system, it is best to initially use SEC as it gives an overall state of efficiency level. Further analysis by using DE best described the design options available for future modifications. From the obtained results, the overall efficiency of seed dryer showed that SEC was calculated to be 50% lower (5.482 MJ/kg water removed) than the commonly recorded dryer efficiency. Analysis of DE revealed a decreasing trend, following the pattern of seed drying rate curve. The average DE was 0.546.

Page 51 - 64

AbstractAutomatic Hand Sanitizer (AHS) is an effective and useful tool to sanitize hands and is used widely in schools, workplace and healthcare settings. However, there are still issues that arise with spray type AHSs as it does not cover all parts of the hand, the volume of the sanitizer is not sufficient or it may miss the hands or be deflected into the air. The purpose of this work is to use numerical modelling techniques to evaluate the spray characteristics of AHS using pressure-swirl atomizer. ANSYS Fluent is used to simulate the spray produced by pressure-swirl atomizer. LISA (Linearized Instability Sheet Atomization) model is used for the primary atomization process while the TAB (Taylor Analogy Breakup) model is used for the secondary breakup of droplets. The parameters that were investigated include the spray angle and the droplet Sauter Mean Diameter (SMD). The simulation was first conducted using water as the atomization fluid to simulate water-based sanitizer spray and validated against experimental data. It was found that the simulation model developed shows good comparisons with experimental data when water was used. In addition, two scenarios were investigated with the validated CFD model: (i) increase in mass flow rate, (ii) ethyl-alcohol atomization for AHS application. Simulation results showed that the increase of flow rate does not affect water atomization but it does affect spray angle and SMD values for Ethyl-alcohol atomization. It is suggested that a higher flow rate can improve the atomization quality and spray coverage of alcohol-based sanitizer liquid for AHS application.

Desalination of Seawater through Gas Hydrate Process: An Overview
Muhammad Saad Khan, Bhajan Lal, Khalik Mohamad Sabil, Iqbal Ahmed
Page 65 - 73

AbstractPotable water shortage affects more than 80 countries and 40% of the world population. It is predicted that over 60% of the human population would be exposed to water shortage by the end of 2020. Marine water represents an infinite water source since 98% of all global water is present in the form of oceans; therefore, seawater desalination is the most logical approach to meet freshwater demands. Currently, two dominant desalination methods are widely applicable includes reverse osmosis and multi-stage flash distillation. Although these technologies have been proven to be reasonably efficient, they still have some disadvantages, i.e., high capital investment or not feasible for minor scale. To overcome the limitations of the existing techniques, new technologies like Electro deionization (EDI), Freeze Separation (FS), Vacuum Compression Distillation (VCD) and Freezing with Hydrates (FH) must be seeking as future applications. Some recent researchers have highlighted the desalination with hydrates can produce cheaper desalted water than the existing available technologies. This study provides a brief review of the recent researches accomplished on the desalination of saline water through gas hydrate technology. It is evident from the literature that small amount of additives or hydrate promoters either significantly enhance the thermodynamic conditions of hydrate formation above the freezing point of water or increase the hydrate crystallization by improving the hydrate formation rates. This review paper will provide the roadmap for the potential application of hydrate technology in the field of water desalination.

Page 102 - 110

AbstractThis study explores a combination of spray drying and refrigeration systems on production of vitamin B1, which is known to be heat-sensitive. It analyzes the effect of drying air temperature on vitamin B1 levels and notes the related influence on production levels. In addition to temperature, productivity is influenced by moisture and drying airflow rates. In this study, air temperatures were set at 80, 110, and 140oC. Air humidity variations were carried out by changing the humidifier’s outlet air temperature to 10, 15, and 20oC. The airflow rate varied at 150, 300, and 450 lpm. High Performance Liquid Chromatography (HPLC) testing methods was used to test the level of damage to vitamin B1 products. By setting the temperature of air passing through the evaporator at 10oC, the drying temperature at 140oC, and airflow rate at 450 lpm, damage to vitamin B1 can be minimized by 7.69%. The drying productivity with the refrigeration system is even 3 times larger than the result of the drying productivity with conventional methode. These results indicate that the combination of spray drying and refrigeration systems with low evaporator temperatures can have a significant positive impact on the production quality of vitamin B1.

Page 111 - 118

AbstractThe natural resources from Indonesia that can be used as an adsorbent are natural zeolite which could adsorb water but less use in cooling application although it is in abundant amount. One of the cooling systems that use less energy is adsorption. The measurement considerations of adsorbent are surface are, pore size, Si/Al ratio, type of zeolite and hydrophilic characteristic. The material being tested in this research is natural zeolite from Yogyakarta and Cikembar, Indonesia. This research analyzes the characteristic of the adsorbent including the BET surface area, pore volume, structural or morphologies characterization, and element composition from each natural zeolite. The result of this study showed that the BET surface area and pore volume of natural zeolite from Yogyakarta are one third smaller than Cikembar, but it has more hydrophilic of Si/Al ratio. Whereas the result of selectivity study between the two prove that both zeolite has better selectivity in each area that can be improve with post treatment or modification.

Meanwhile, the solar power measurement data taken in 111 seconds are recorded and displayed in graphical form between solar powers (W/m2) to seconds (s). The lowest wind speed measurement result is 0 m/s for some time and the highest is 3 m/s for 2880 seconds, while for the average measurement result is 1 m/s. While the lowest solar power measurement results are 20 W/m2 for some time and the highest is 770 W/m2 at 14:14:43 (23 s), while for the average measurement is 360 W/m2. Referring to such measurement data, the potential for wind power generation is weak, so it is almost impossible to produce energy efficiently using wind power, as the wind speed must be greater than 4 m/s. While based on the measurement profile of solar power, from time to time can reach 770 W/m2 which has the potential to generate electricity. In addition, based on these two measurement results, they show a nonlinear random profile. Thus the installation of hybrid wind and solar power plants must have a nonlinear control system design.

AbstractThe performance of a Savonius wind turbine was studied for urban power system application. The aim of the study was to analyze the effect of Omni-Directional Guide Vane (ODGV) on rotor performance. The wind tunnel experiment had been carried out on a Savonius rotor model. The ODGV was placed around the Savonius rotor in order to increase the ambient wind velocity to the wind turbine. The tests were performed at a different ODGV slope angle and incoming wind direction. The maximum power coefficient (Cpmax) obtained was 0.125 at 60o wind direction. The maximum power coefficient of a Savonius wind turbine with ODGV was 21.46% higher than the Savonius wind turbine without ODGV. The result showed that the ODGV had the potential to increase the performance of the Savonius wind turbine.

Page 136 – 141
AbstractThe analytical solution to the internal fluid flow induced by an oscillating plate with the other parallel plate stationary is derived and the results explored fully. The unsteady analytical solution is obtained by using Duhamel’s theorem. The result is analysed nondimensionally with respect to variations in the gap, the time and the parameter ?? . Results reveal that the wide variation in fluid flow is strongly depending on the dimensionless parameter ?? . The present governing equation is modelled numerically with same conditions and at selected ?? = 1 and ?? = 10, respectively, the numerical results are able to match with the analytical solution remarkably well.

Page 142 - 149

AbstractEscalating fuel prices and carbon dioxide emission are causing new interest in methods the waste heat rejected to the environment and at the same time that can minimize the usage of fuel. One viable means is the conversion of exhaust engine waste heat to a more useful form of energy. The aim of this study is to model and investigate the thermal performance of an Organic Rankine Cycle (ORC) system which is used as waste heat recovery of exhaust gas from a turbofan engine. A simulation study has been done on the ORC in two different types of system configurations in order to predict which design will give a better thermal performance. Parameters such as net power output and the ORC system efficiency are used to represent and compare the thermal performance of both of the designs. The simulation is done by using MATLAB and REFPROP. The selection of the best configurations is based on the thermal efficiency of the system. It is found that the ORC system with superheater gives a better thermal efficiency that the one with preheater. The results also show that thrust specific fuel consumption (TSFC) of the turbofan engine reach a lower value by using ORC with superheater instead of with preheater. Hence implementation of ORC system for waste heat recovery to an aircraft engine can bring a great potential to the aviation industry.

Effect of Flow Patterns on Two-Phase Flow Rate in Vertical Pipes
Tarek Ganat, Meftah Hrairi
Page 150 - 160

AbstractDuring two-phase gas-liquid flow in pipelines, the fluids may take up different flow patterns. The exact nature of the flow pattern varies according to conduit size and geometry, fluids’ properties, and each phase’s velocity. When the conduit size and fluid properties are constant, then any changes in individual flow rates will result in changes to the flow regime. Predicting the flow patterns within a pipe is essential as it is a critical parameter that determines the pressure gradient and liquid holdup in the conduit. This paper presents the results in predicting the multiphase flow patterns and their effects on flow measurements in vertical pipes. The study was conducted on vertical upward multiphase flow using well and reservoir properties. OLGA dynamic simulator was used to predict flow pattern in a vertical pipeline for 35 oil wells using electrical submersible pumps (ESP) with external pipe diameters of 3.5 inch. The predicted oil flow rates of 35 ESP oil wells were compared with measured flow rates and a good agreement was observed. Indeed, the results indicated that the variation of the flow pattern had insignificant impact and it was insensitive to the accuracy of the flow rate values of the ESP oil wells where the average overall flow rates accuracy was lower than +/-10%. Additionally, simulation results demonstrated a promising model performance and showed the magnitude of possible variation between the oil rates measured with different methods.

AbstractFlow characteristics of a circular jet which was injected normal into the crossflow on flat plate, has been investigated by temperature measurement and flow visualization. The effect of jet-crossflow momentum flux ratio on jet flow behavior was studied by fixing the crossflow velocity and changing the velocity of jet flow. The experimental study was divided in two parts. First part, the flow visualization was done in water tunnel using Laser Induced Fluorescence (LIF) technique. Second part, the temperature of air jet flow was quantitatively measured with thermocouples and visualized the jet flow trajectory with smoke technique. The jet flow after injecting into crossflow had dome-shape structure and attached to the downstream surface for case of jet-crossflow momentum flux ratio less than 0.25. The results showed that the dome-shape structure was observed at the near field, while the Counter Rotating Vortex Pairs, CRVP appeared after that. When the jet was deep penetrated into the crossflow and moved away from the surface, which indicated jet-crossflow momentum flux ratio higher than 1.0, the jet flow had kidney-shape cross section and CRVP suddenly occurred in jet cross section behind the jet exit.

Page 175 - 188

AbstractCity urbanization induces many mega mixed development projects. Expansion and utilization of the underground space is an alternative to overcome the cost of superhigh-rise buildings. Storing and managing vehicles in underground space predispose these buildings to fire hazards. Some passive requirements stated in Uniform Building By-Law Malaysia 1984 are difficult to comply with. Limitations in allocating fan rooms and large duct work design are some of the major drawbacks in the design of a large enclosed underground parking structure. Because the reversible longitudinal smoke extraction systems are well applicable to trains and road tunnels, this paper investigated the performance of this smoke extraction system in a confined long and flat underground parking structure and enlarging the fire compartmentation by four times. In this reversible scheme, fan shafts installed at fire zones are operated as extraction shafts, whereas fan shafts positioned in adjacent areas are running as makeup air. Results showed that the reversible longitudinal smoke extraction system is applicable to retain the smoke within the fire zone in the underground parking structure.

Effect of Location in a Cylinder Wake on Dynamics of a Flexible Energy Harvesting Plate

Page 189 - 198

AbstractFlexible plate in the wake of a bluff body may be exploited to harvest energy, for example by attaching piezoelectric sheets on both surfaces of the plate. A computational investigation on flow-induced vibration of a flexible plate in the wake of a cylinder is undertaken to understand the effects of plate location on their vibrations and hence, energy harvesting potential. Based on cylinder diameter D (0.1m), flow at a sub-critical Reynolds number of 10000 was considered in the present study. The fluid-structure interaction was implemented via a closely-coupled partitioned scheme that employs a Scale-Adaptive Simulation (SAS) of the Shear Stress Transport (SST) method to model flow turbulence. A flexible plate was placed at several locations (streamwise: x/D = 0.5, 1.0, 1.5, 2.0; crossflow: y/D = 0, 0.25, 0.5) downstream of the cylinder and their flow-induced response were compiled and analysed. Benchmarking of present model showed good agreement with previous experimental investigations. Results suggest that maximum deflection may be found if flexible plate is placed in the region between cylinder surface and x/D < 1.0. Oscillation of flexible plate placed at y/D = 0.25 shows similar amplitude, if not slightly higher, than if plate is placed at wake centerline. Present findings suggest that energy output may be optimised by positioning flexible energy harvesting plates at favourable locations in the wake region.

AbstractThe development of biocomposites has increased due to their biodegradability, renewability, and high specific strength which are comparable with other polymer composites. Even though, the conventional composites are still in high demand due to their durability, however, it cannot decompose and the accumulation of these wastes for a long period is harmful to the living things and to the environment. Therefore, in this study the biodegradable polymers, polycaprolactone (PCL) and starch were selected in this study to synthesize bionanocomposite incorporated with microfibrillated cellulose (MFC). The microfibrillated cellulose (MFC) was extracted from cocoa pod husk (CPH–MFC) and was mixed with PCL and starch, where its amount was varied between 3-10wt%. The prepared bionanocomposites were characterised in terms of its water uptake rate, and structural and thermal properties using Fourier transform infared spectroscopy (FTIR) and differential scanning calorimetry (DSC). The morphology analysis using scanning electron microscope (SEM) shows that the CPH– MFC extracted was in nanoscale size. The percentage of water uptake of the prepared bionanocomposites increased with the amount of CPH–MFC. Meanwhile, the FTIR spectra of the prepared bionanocomposites showed almost similar characteristic peaks with the FTIR spectra of pure PCL. DSC analysis showed that the melting temperature increased as the amount of CPH–MFC increased. This study justifies that the incorporation of CPH–MFC with the PCL–starch matrix improved the water uptake rate and thermal properties but did not show significant changes to the structure of PCL.

AbstractNowadays, keeping environment at comfort zone with conventional cooler become expensive, especially in wide and semi outdoor spaces. Evaporative cooler which offer a healthy, non-harmful materials, and low cost can be an alternative to keep environment healthy and comfortable. The objective of this experiment is to determine and compare the performance of direct evaporative cooler embedded with heat pipes and without heat pipes. Heat pipes are placed in the section before cooling pad and work as indirect stage. Evaporator sections of heat pipe are placed before cooling pad and the condenser section are placed in the addition sump. The results show that the saturation efficiency of both system increase along with the increase in inlet temperature and decrease along with the decrease in relative humidity. The saturation efficiency also decreases along with the increase in air velocity. The results also show that the saturation efficiency of modified evaporative cooler using heat pipe is higher than direct evaporative cooler. The addition of heat pipes can increase the saturation efficiency of direct evaporative cooler up to 1.03 without addition more power consumption.

Page 218 - 232

AbstractIn this paper we study the effect of Brownian motion and Thermophorosis on Maxwell nanofluid flow over a linearly stretching sheet under the influence of oblique external magnetic field. The impact of cross diffusion, frictional heat and irregular heat are considered to be prominent. The effect of inclination of magnetic field and nonuniform heat source/sink on fluid velocity, temperature and nanoparticle concentration are analyzed and depicted in graphs. It is observed that as inclination of magnetic field increases, temperature and nanoparticle concentration also increases whereas fluid velocity decreases. The effect of Dufour number D, Eckrect number Ec, Prandtl number Pr, Brownian motion parameter Nb, Thermophorosis parameter Nt, and Lewis number Le are also studied.

Effect of Isothermal Heat Treatment on Hardness of X7475 Aluminium Alloys
Abubakar Kazeem, Nur Azam Badarulzaman, Wan Fahmin Faiz Wan Ali
Page 233 - 239

AbstractThe heterogeneous nature of microstructure in most as-cast alloys has created the unique properties for an ally before heat treatments. The scanty nature of scholarly articles on the effect of heat treatments on the hardness of new alloys produced from recycled aluminium alloys prompts this investigation. In this work, we upgraded from 3 series to 7 series alloys to form a new material. Previous attempts were also silent on the Alcao Green Letter specifications of the 7 series alloys, hence producing a 7475 alloy that may not be within the Alcao specifications. This paper presents the result of preliminary studies on new experimental X7475 Al-alloy that was produced per Alcoa Green Letter specifications, with variations of Zn (4.0 – 5.0 wt.%), Mg (1.00 – 1.50 wt.%) and Mn (0.025 – 0.075 wt.%), then subjected to microhardness probe under a load of 490.3mN (0.05Hv) and 10sec duration after isothermal and isochronous “O”, T4 and T6 heat treatments. Heating and cooling rates were controlled during heat treatment processes to investigate the effects on the formation of the MgZn2 and other precipitates on the mechanical properties of the alloy. Peak obtainable hardness value of 140.45 Hv and 134.32 Hv are attained within the T6 and T4 conditions in an alloy of 4% and 5% Zn respectively. The increase in wt.% of Zn favours mechanical properties while reverse is the case for Manganese. This result is an indication of the load bearing capacity of our alloy. It has also demonstrated the success in upgrading the 3 series to 7 series alloys from secondary materials. However, the result could be improved on after composition, heat treatments and production route optimization.

AbstractThe great properties of magnetorheological (MR) fluid have amplified the request to create more type of MR fluid. Despite numerous studies suggesting many formulations in this area, their role in the vehicle industry is still far from ready for any practical applications. In this study, individual components of the carrier fluid in an original equipment manufacturer (OEM) smart fluid preferably acknowledged as MR fluid that contributes to the development of stress has been investigated. The carrier fluid components were identified through gas chromatography (GC) techniques coupled with mass spectrometry (MS) analysis over a range of retention time and computer matching with the National Institute of Standards and Technology (NIST) library. The data is statistically analysed to predict the potential material use as a carrier fluid in MR fluid. It was found that a total of seven components with a noble match and high probability were successfully identified. The MR fluid exhibited oily properties were related to the presence of alkane hydrocarbons components, of which Heptadecane (0.98%), Nonadecane (0.61%), Tetratetracontane (1.72%) and Eicosane (7.94%) respectively. The results also revealed that the number of additives present in the mixture was more than one with a higher concentration percentage. The additives have a major influence on the overall magnetorheological effects of the MR fluid.

AbstractInspired by enhancement of vortex induced vibration energy harvesting as a green and renewable energy source, several geometry shapes such as cylinder, square, triangle, D shape, and U shape bluff body were studied in terms of vortex shedding frequency, vorticity and pressure difference in order to determine the best bluff body for piezoelectric film. A 2-dimensional computational fluid dynamic (CFD) simulation analysis is carried out with the length and height of bluff body fixed as 0.1 m and air flow used for simulations are 0.0438 m/s, 0.292 m/s, and 0.73 m/s which corresponds to Reynolds number (Re) of 300, 2000, and 5000. Overall, cylinder, triangle, and D shape bluff body gives a higher vortex shedding frequency and Strouhal Number (St) compare to square and U shape. Triangle bluff body was able to maintain the highest vorticity for all three difference air speeds. It is found that maximum vorticity point will move backwards when higher air velocity is simulated. Nevertheless, triangle bluff body gave the highest-pressure difference reading among all tested shapes. In conclusion, triangle shape bluff body is the most suitable shape for inducing vortex shedding to piezoelectric film and it is suggested the length of the piezoelectric beam is between 0.05m and 0.15m.

Page 264 - 271

AbstractThe multipurpose Irradiator in Indonesia with capacity of 2 MCi Co-60 radioactive source was built to support food security. When not operated, the Co-60 is stored in the pool to keep the radiation not to exposure to environment. The decay heat generation of Co-60 could increase the pool water temperature. To improve safety especially during SBO conditions, the pool water should be passively cooled using a vertical straight wickless-heat pipe. The objective of this experimental study is to investigate the heat transfer phenomena and the thermal performance of the vertical straight wickless-heat pipe as passive cooling system in the irradiator pool. Vertical straight wickless-heat pipe with inner diameter of 57 mm and total length of 1000 mm was charged with demineralized water of working fluid with filling ratio of 55%. This experiment was conducted with varied pool temperature, and air coolant velocity in the condenser section. The experiment results obtained that the lowest thermal resistance of wickless-heat pipe is 0.03 °C/W when heat pipe is operated at pool temperature of 90ºC and air coolant velocity of 1 m/s. It can be concluded that the vertical straight wickless-heat pipe has good thermal performance to absorb the heat generation in the irradiator pool. The results of this study are expected to provide a more complete management thermal knowledge to improve the safety of Irradiator.

Page 1 – 9

AbstractThis study presents a numerical investigation on developing flow of inelastic nonNewtonian fluids in a circular tube having alternating superhydrophobic grooves and ribs arranged transversely to the flow direction. Laminar, steady and incompressible flow of non-Newtonian power-law fluid flowing in a circular tube having superhydrophobic transverse grooves of L = 0.1 and delta = 0.5 is considered. The influences arising from the presence of superhydrophobic surfaces (SHS) on radial velocity profile development, centerline velocity distribution and hydrodynamic entrance length are examined. For Reynolds numbers ranging from Re = 1 × 10^-4 to Re = 1, numerical results show that the hydrodynamic entrance lengths arising from flow over superhydrophobic transverse grooves for non-Newtonian fluid with powerlaw index in the range 0.5 ? ? < 1.5 are consistently longer than that of smooth surface.

Flow Characteristics of Transition Region Between Laminar and Turbulent Gas Flows Through Micro-Tubes
Kenshi Maeda, Chungpyo Hong, Yutaka Asako
Page 10 - 19

AbstractFlow characteristics in the transition region between laminar and turbulent gas flows through micro-tubes were experimentally investigated. The experiments were performed for nitrogen gas flowing through two stainless steel micro-tubes of D = 124 and 162 µm and two fused silica micro-tubes of D = 100 and 151 µm. The Mach numbers and gas bulk temperatures at the inlet and locations near the exit were also obtained by measuring stagnation temperatures, stagnation pressures, pressures at locations near exit and mass flow rates. The average Fanning friction factors also were obtained. The mass flow rate levels off in the transition flow region for micro-tubes as the stagnation pressure increases. The Mach number increases with an increasing Reynolds number in the laminar flow region. However Mach number decreases when Reynolds number goes higher in the transition flow region since the mass flow rate stays nearly constant with an increase of the stagnation pressure in the transition flow region. On the other hand, the bulk temperature increases in the transition flow region. This was validated by measuring wall temperature of micro-tubes whose outer walls are thermally insulated. The decrease in Mach number and the increase in the bulk temperatures in the transition flow region are the dominant scaling effect for the smallest diameter micro-tubes.

AbstractEffect of Coriolis force and magnetic field on thermal convection in an anisotropic porous medium has been studied numerically. Linear stability analysis has been implemented to verify the presence of Coriolis force and magnetic field on the thermal convection in a horizontal anisotropic porous medium heated from below. The Darcy model is used for the momentum equation and Boussinesq approximation is considered for the density variation in the porous medium. The eigenvalue problems of the perturbed state were obtained from a normal mode analysis and solved using Chebyshev Tau method numerically with respect to upper free conducting and lower free conducting boundary condition. By using Fortran software, it is found that the thermal anisotropy parameter destabilized the system while the effect of Coriolis force and magnetic field help to stabilize the system and can delay the onset of convection and mechanical anisotropic parameter advanced the onset of convection in the system.

AbstractSolar intensity, collector design and its orientation are the key parameters that affect the performance of any solar collector. This work presents mathematical modelling of solar radiation for studying the effects of collector slope angle on the radiation falling on a solar collector and the determination of the collector optimum slope angle for Kano, Nigeria (12.05°N). To study such effects, two computer programs were developed for studying the effects of solar collector slope angle and optimization of the collection which was carried out using Engineering Equation Solver (ESS). Results showed that for maximum energy collection over the year, the collector should be tilted (in the order of priority); to the optimum angle of each month, to the seasonal tilt angles (i.e. horizontal from April to September and then set to Kano’s latitude plus 15° for the other months) or fixed to the latitude of Kano. Sloping of solar collector to the monthly optimum tilt angle results in significant radiation gain throughout the year with 28.6 and 24.8% in December and January respectively. Also the maximum radiation obtainable in each month is received and there will be no radiation loss throughout the year. Also energy received by the collector for generating hot water or steam in solar thermal collector was found to be affected by the collector’s orientation and slope angle.

AbstractThe thermal convection in a horizontal binary fluid layer saturated an anisotropic porous medium with the effect of non-uniform temperature profile is studied analytically by linear stability analysis. The generalized eigenvalues problem subjected to various boundaries conditions are solved numerically using Galerkin method. The effects of solute Rayleigh number, Lewis number, mechanical anisotropy and thermal anisotropy parameters corresponding to the six basic temperature profiles on the stationary thermal convection are shown graphically. It is found that the effects of thermal anisotropic parameter, Lewis number and solute Rayleigh number are to reinforce the stability of the system while the effect of mechanical anisotropic parameter is to advance the onset of convection.

AbstractRenewable energy is an alternative approach of energy supply that meets the needs of the present generations without compromising the ability of future generations to meet their own needs. One type of renewable energy is solar energy. Solar energy systems convert solar energy into useful energy. In designing a solar collector, there are predictable and unpredictable parameters that are considered. Predictable parameters include performance characteristics of collector and mainly concern weather data such as solar radiation, ambient temperature, wind speed, direction, and other parameters is performance characteristics of collectors. This work analysed the use of the f-chart method in design liquid solar heating systems due to its simplicity and ability to estimate the fraction of total heating load supplied by the solar heating system. This method is very commonly used in designing for both active and passive solar heating systems, especially in selecting sizes and type of solar collectors that provide the hot water and heating loads. In this research, the data of the project is analysed to calculate based on the f-chart graph. The results show that the area in Melaka around the vicinity of Ayer Keroh is suitable for the installation of the flat-plate solar collector. The total annual heating load of domestic hot water in Melaka is 9.55 GJ and the annual fraction of the load supplied by solar energy is 78.42% which is suitable for implementation and installation in Ayer Keroh, Melaka.

Page 68 - 77

AbstractThe utilization of geothermal energy needs to be improved to support energy diversification and sustainable environmental development. Applying heat pipes as a heat transfer device, will overcome several obstacles to increase the use of geothermal energy, especially low enthalpy geothermal energy. The objective of this study is to investigate the thermal performance of heat pipe usage for heat distribution from low enthalpy geothermal fluids to agricultural dryers. Geothermal fluid simulator (hot water) uses water that is heated by 9000 Watts heater and is flowed by a pump. The heat pipe has a length of 700 mm OD 10 mm, while the heat pipe filling ratio is 50 %. In this experiment, the number of heat pipe used are 42 pieces. The condenser uses a total of 181 fins with a size of 76 x 345 mm. Fin from aluminum material with 0.105 mm thickness is used in this experiment. The result show that the heat pipe could be carried out as a Heat Pipe Heat Exchanger (HPHE) in applications of low enthalpy geothermal heat. The value of HPHE effectiveness increases as the increase of hot water temperature on the side of the inlet evaporator and tends to decrease as the air velocity increases. The biggest HPHE effectiveness value is 61,427 %.

AbstractHotspot related problem can be detrimental to Sulphur Recovery Unit (SRU) material lifespan. One of the causes of the hotspot is susceptible high vibration level of multi components in SRU. In this project, the vibration level of the sulphur recovery unit was experimentally measured. The main objective of the measurement is to technically assessed the unit for maintenance management purpose. Two types of measurements were performed. Firstly, bump tests were conducted to accurately determine the natural frequency of the oxygen intake pipeline. Secondly, the vibration level is then mapped to various components in the system according to the process conditions. By analysing this map, the correlation between the vibration levels, natural frequency and process conditions that can cause excessive vibration of the SRU can be specifically verified.

Page 88 - 99

AbstractThis paper discusses the methods to obtain a correlation of local thermal resistance for heat transfer of a double-layered microchannel heat sink (DL-MCHS) with parallel flow configuration. Based on the energy balance in a thermal resistance network constructed for the DL-MCHS, the local thermal resistance which consists of conductive, convective and capacitive thermal resistance has been obtained as a function of governing parameters including the channel geometrical parameters. The results predicted for different channel width with the correlation are compared with the results obtained through numerical. Good agreement was found between simulation and correlation results, which indicates that this correlation could be used to predict the local temperature along the flow direction for DL-MCHS with different channel width.

AbstractNanofluid has been drawing attention in various engineering applications in past decade due to its superior heat transfer characteristics than conventional working fluid. From past researchers, it is found that behavior of nanofluid can be greatly varied by various factors such as method of preparation, concentration/type of suspended nanoparticles and type of base fluid used. Due to the desire to possess nanofluid with more advantageous characteristics, dispersion of different nanoparticles into base fluid has led to a novel product which is called hybrid nanofluid. Different types of hybrid nanofluid were prepared and studied by former researchers in accordance with parameters required in their studies. Based on literature review, hybrid nanofluid shows greater heat transfer performance and rheological properties compared to base fluid and mono nanofluid. This paper reviews the preparation method, stability investigation method, thermophysical properties and heat transfer performance of hybrid nanofluid in various heat transfer applications. Apart from that, this review outlines challenges regarding hybrid nanofluid and some suggestions to improve future researches in this area.

AbstractPhotovoltaic (PV) panel is directly converted solar irradiance into electrical energy. The temperature of the PV panel increased as it absorbs solar irradiance lead to a reduction in its output power. This undesired impact can be prevented through the use of a cooling system with PV panel. In this research, a water cooling system was designed to the PV panel in order to reduce its temperature. The objective of this research is to predict the temperature distribution of the PV panels without and with water cooling system. In the water cooling system, the water flow over the front surface of the PV panel in order to reduce the temperature of the PV panel. In addition, this research also focused on the impact of inlet water temperature on the performance of water cooling effect. The result of this research shows that the average temperature distribution of the PV panel without water cooling system is higher than that with water cooling system. The average temperature of the PV panel without cooling system is 50.68 °C. For the water cooling system, the PV panel with the inlet water temperature of 20 °C can be reduced the temperature of PV panel by 15.63 °C as compared to the PV panel with inlet water temperature of 45 °C. This research could be beneficial for researchers and students to understand the effects of temperature to the PV panel.

Jia-Wei Zuo, Kok-Cheong Wong, Hoon Kiat Ng
Page 147 - 156

AbstractThe present study numerically investigated the thermal performance for three-layered microchannel heat sink (MCHS) with horizontally tapered channel profile. The problem is solved using a three-dimensional conjugate heat transfer model. Parallel flow and counter flows configurations are investigated for their maximum thermal resistances. The effects of different tapered geometries of microchannel within the multi-layer MCHS are investigated by varying the channel inlet width and channel outlet width. The numerical results show that the three-layered MCHS with CF1 flow configuration give the lowest value of thermal resistance for low value of channel inlet size (converging channel profile) while the parallel flow configuration shows lowest value of thermal resistance among all the flow configurations at high value of channel inlet size (converging channel profile). The results also show that counter flow configurations alter the peak temperature location at the base of heat sink along the flow direction toward the center of the channel, rendering better temperature uniformity.

Tribological Analysis of Modified RBD Palm Kernel Containing Anti-oxidant Additive using Four-ball Tribotester
Muhammad Arif Dandan, Syahrullail Samion, Wan Mohamad Aiman Wan Yahaya, Faris Hadi
Page 157 – 164
AbstractVegetable oils are becoming increasingly important as an alternative lubricant oil due to their non-toxic, renewability and biodegradability characteristics. They are considered as promising candidate to replace the conventional petroleum based lubricant which are constantly threatening our environment. However, most of the vegetable oils are facing common issue which is low oxidative stability that limits them to be used directly as bio-lubricant oil. This work studied the application of TertiaryButyl-Hydroquinone (TBHQ) as synthetic base anti-oxidant agent inside palm kernel oil (PK). The effect of load on the tribological performance of lubricant formulated were tested using four-ball tribo-tester according to ASTM D4172 standard with duration of 60 minutes for each test. The results obtained were compared to the commercialized mineral (MO) and semi-synthetic engine oil (SSO) for the reference purpose. Based on the result obtained, the coefficient of friction of palm kernel is smaller as compared to commercialized petroleum based oil. This is contributed by the presence of long polar fatty acid structure that acts as a protective film between two rubbing surfaces. The addition of anti-oxidant, TBHQ also helps to further reduce the friction coefficient of PK. However, the wear scar diameter of PK and PK+TBHQ are larger compare to MO and SSO. Thus, it can be concluded that TBHQ manage to enhance the friction reducing performance of PK by lowering the value of friction coefficient. However, there is still room improvement for the anti-wear properties of palm kernel oil.

Page 165 - 174

AbstractIn this study, the problem of MHD micropolar nanofluid boundary layer flows over an exponentially stretching/shrinking sheet with radiation and suction effect is considered. The Buongiorno’s nanofluid model is applied to the problem. The governing equations are first transformed to the coupled nonlinear similarity equations by using similarity transformations. The resulting equations which is in ordinary differential equations form are then solved numerically by using shooting method. Triple solutions are observed to exist for the flows. A comparison with existing solutions in literature for specific case are made to assess the accuracy of the present results. Further, the flows profiles are examined, and it is found that the presence of suction parameter will contribute the occurrences of triple solutions.

AbstractGround vertical temperature profile at various depths is a major key in designing phase of the use of earth heating and cooling techniques for buildings, offices and greenhouses like earth to air heat exchanger (ETAHE), Earth-Air Tunnel (EAT), Ground Air Collector (GAC) and water Quanat. Annual undisturbed soil temperature is very important parameter to investigate earth to air potentials. The present experimental study was conducted in two different sites in South-west of Algeria, in the city of Bechar (arid region) starting from ground surface to 1.5 m depth. The obtained results show that at the ground surface temperature was 35.2 °C for both sites. At 1.5 m of depth, the temperature was 29.2 °C and 28 °C in site n°1 and n°2 respectively. Temperature values remain constant after 70 seconds. The study results serve as a benchmark for other studies and help researchers interested to study this renewable energy source.

AbstractThe present paper investigates the impact of velocity slip and thermal slip on the peristaltic transport of a Herschel-Bulkley fluid, flowing through a uniform two dimensional porous tube under the assumptions of long wavelength and low Reynolds number. The mathematical representations of temperature and velocity fields, pressure gradient, and stream function have been found through the closed-form solutions of the energy and momentum equations. Numerical integration has been employed to compute the frictional force and pressure rise. The influence of relevant parameters in the problem have been discussed and presented graphically. The results reveal the increasing effects of thermal and velocity slip on pressure rise and temperature. Also, trapping phenomena of the Herschel-Bulkley fluid is discussed. The volume of the bolus is observed to increase along with the velocity slip parameter.

AbstractThis study involved the performance of energy and exergy analysis on a 200 MW Steam cycle power plant (SCPP). The aim is to investigate the effect of using different number of feed water heaters (FWHs) on the cycle performance. Several simulation analyses were conducted in this study on a MATLAB platform. The computer model used was based on natural gas combustion, enthalpy balances, energy balances, and entropy changes of the SCPP. The real case study was simulated on a validated model of the SCPP for Shahid Montazeri Power Plant. The exergy destroyed within each components system and the exergy efficiency are determined to study the irreversibility of the system and identify the chances for the enhancement of the power system. Based on the result of the analyses, the energy and exergy efficiencies of the SCPP were determined to be about 37.52 % and 41.7 %, respectively. In the SCPPs, the combustion chamber (boiler) contributes the highest exergy destruction rate (around 48 % of the exergy value of the gas) among the main components of the power system.

AbstractSolar radiation could be harnessed to produce thermal and electrical energy. The solar thermal radiation is very advantageous as it can be harnessed easily and at an affordable cost. Electrical energy could be produced from the solar radiation by photovoltaic process and have an efficiency of 20-40%. This process is currently limited to its material and manufacturing costs, inefficiency under thermal load and relatively lower performance under low clearness index conditions. By using both properties, a solar photovoltaic-thermal (PV/T) hybrid could be designed to increase thermal and electrical efficiency during low clearness index. The study of the potential application of Thermoelectric Generator (TEG) in PV/T applications is highlighted to see the opportunities that are available in this field of study. Computational Fluid Dynamics (CFD) simulation using COMSOL software was carried out.

Heat Transfer Analysis of Sodium Carboxymethyl Cellulose Based Nanofluid with Titania Nanoparticles
Abid Hussanan, Nguyen Thoi Trung
Page 248 - 256

AbstractIn this paper, an analysis is made for heat transfer unsteady flow of nanofluid over semi-infinite vertical plate with leading edge accretion/ablation. The impact of viscous dissipation in energy equation with Newtonian heating condition is also considered. Tiwari-Das model is used to incorporates the effects of nanoparticles volumetric fraction. Sodium carboxymethyl cellulose (SCMC) is considered as based fluid containing titania (TiO2) nanoparticles. Similarity transformations are employed to transform the unsteady partial differential equations into a system of ordinary differential equations. The transformed equations along with relevant boundary conditions are solved numerically by Runge Kutta Fehlberg fourth-fifth order (RKF45) method in MAPLE software. The analysis shows that velocity and temperature field in the respective boundary layers depend on different physical parameters, namely Prandtl number, Eckert number, Casson parameter, Newtonian heating parameter, accretion/ablation parameter and nanoparticle volume fraction. Temerature shows higher value for Blasius flat plate, while for Rayleigh-Stokes is the lowest.

Page 257 - 266

AbstractNanofluid has been drawing attention in various engineering applications in past decade due to its superior heat transfer characteristics than conventional working fluid. From past researchers, it is found that behavior of nanofluid can be greatly varied by various factors such as method of preparation, concentration/type of suspended nanoparticles and type of base fluid used. Due to the desire to possess nanofluid with more advantageous characteristics, dispersion of different nanoparticles into base fluid has led to a novel product which is called hybrid nanofluid. Different types of hybrid nanofluid were prepared and studied by former researchers in accordance with parameters required in their studies. Based on literature review, hybrid nanofluid shows greater heat transfer performance and rheological properties compared to base fluid and mono nanofluid. This paper reviews the preparation method, stability investigation method, thermophysical properties and heat transfer performance of hybrid nanofluid in various heat transfer applications. Apart from that, this review outlines challenges regarding hybrid nanofluid and some suggestions to improve future researches in this area.

AbstractAluminium Nitride (AIN) is classified in the 3rd nitride ceramic materials and able to emit the lights at shorter wavelength of 210 nm with high band gap up to 6 eV. In addition, with thermal conductivity up to 140 W/mK has made this material in demand for electronic devices applications such as light emitting diode, laser diode and photodetector for the ultraviolet region. However, previous researchers have confirmed the existence of defects in the microstructure of AlN that affected the properties of this material during the growth process. Hence, high-temperature annealing heat treatment is utilized as one of the methods to cure the problems of AlN thin film. Therefore, this paper is about to identify the effects of high-temperature annealing heat treatment on the microstructure of AlN. The changes on microstructure were observed through Transmission Electron Microscopy after the annealing process. The results showed an increase of the annealing temperature contributed to the reduction of defects in the microstructure of AlN.

AbstractFire can be formed when these three elements, hot, oxygen, and combustible materials, are present. It produces heat and light through a chemical process of oxidation reactions that occur rapidly. It is widely known that a human’s life on the earth cannot be separated from the fire. But we often hear a phrase about the fire: ‘friendly when it is small, deadly when it is big’. Based on this expression, we can say that the fire is not only furnishing benefits to humans but it also can destroy property and killed many lives each year. Therefore, a fire protection should be given priority in our daily life, especially the use of fire resistant doors in commercial and office buildings. Kapok, a natural fiber, which has a low thermal conductivity has been selected and examined in this study as a fire-resistance material. The objective of this study was to find the resistance of gypsum when mixed with kapok fiber. The laboratory works involved the preparation and testing of composite samples of gypsum and kapok fiber, which were prepared with different thicknesses, namely 6.4mm, 9.5mm, and 12.7mm. Then composite samples of three different compositions, namely 1000g of gypsum: 10g of kapok, 1000g of gypsum: 20g of kapok, and 1000g of gypsum: 30g of kapok were prepared for each of those thicknesses. All the composite samples were burnt, in accordance to MS 1073 (1996), in a combustion chamber that had been designed and fabricated in Combustion Laboratory, Faculty of Mechanical Engineering. The experimental results revealed that the composite sample of 12.7 mm thickness gave the highest fire resistance for all the prescribed compositions while the composite sample of 30 g of kapok fiber produced the highest fire resistance compared to other two compositions. In short, a composite mixture of gypsum and kapok fiber has the potential to be used as a fire-resistance material in manufacturing of fire resistant doors, walls, and ceilings for the building construction sector.

Numerical Solution of Boundary Layer Flow over a Moving Plate in a Nanofluid with Viscous Dissipation: A Revised Model
Siti Norfatihah Zulkifli, Norhafizah Md Sarif, Mohd Zuki Salleh
Page 287 - 295

AbstractModel of boundary layer flow over a moving plate in nanofluid with viscous dissipation effect is revisited. A new boundary condition is applied with the assumption that there is no nanoparticle flux at the surface. The nanoparticle volume fraction on the boundary is passively control rather than active control and this makes the model more realistic. A similarity transformation is introduced to reduce the governing non-linear partial differential equation into ordinary differential equation. The ordinary differential equations are computed numerically through numerical method namely Runge-Kutta Felhberg (RKF) technique. Validations of the result has been made by comparing the present results with results from the previous studies. In this study, it is found that the presence of viscous dissipation contributes to an increase in temperature profile. In addition, it is observed that an increment in Brownian motion parameter produce negligible effect on temperature profile. Furthermore, both nanoparticle concentration and temperature profile intensify with an increase of thermophoresis parameter.
