Abstract

This work aims to study the parameters that had been used in designing a standing waves thermoacoustic rig for investigation of the turbulence characteristics in oscillatory flow. In this work, Design Environment for Low-amplitude Thermoacoustic Engines (DELTAEC) has being used to design the thermoacoustic rig. The voltage supplied and the frequencies were varied to predict the pressure and velocity at each segment. The data obtained had been compared with previous works for 10 to 60 Volt and drive ratio range of 9.0% to 10.3%. The results also reveal that increment of voltage amplitude by 10 volts caused deviation of data from 2.17 % to 20.35%, increment of velocity amplitude from 1.57% to 2.70%, and increment of drive ratio from 2.17% to 3%. The predicted critical Reynolds number occurred from the cone to the middle of the minor segments.
