Abstract

In this study, the effect of magnetic field on temperature field and nanofluid current in a flat tube is investigated numerically. The water-based fluid and nanoparticles are iron oxide, copper oxide and aluminum oxide with a diameter of 1 nm. The finite volume method has been used for numerical modeling. Nanofluid is considered as single phase. Both flow regimes are considered laminar and turbulent. With the addition of nanoparticles and increasing the volume fraction, the amount of heat transfer and pressure drop in the turbulence flow is more than the laminar flow. Applying a magnetic field changes the velocity field in the flat tube by creating a Lorentz force. By applying a magnetic field and increasing its intensity, the amount of Nusselt number in the turbulent current increases by about 40%. In the state with and without magnetic field, nanofluid water-iron oxide has the highest heat transfer rate compared to other states.
