Computational study on thermoacoustic heat engine for proposing a new method renewable technique

Thermoacoustic Heat Engine is a renewable technology in the energy conversion field. This system is a suitable technology for catching the waste heat where it provides about 400 °C to 600 °C to fulfil the valuable work. The aim of this study is to determine the appropriate parameters in thermoacoustic heat engine for standing wave and analyse the highest performance of acoustic power. Delta EC software is used to do the code for simulating the thermoacoustic heat engine where it focus on four parameters which are frequency, pressure, temperature and heat exchanger length in order to know the better value used for design a thermoacoustic system. As result, the acoustic power with 2 mm of Hot Heat Exchanger (HHX) and 20 mm of Cold Heat Exchanger(CHX) length which gets from the graph of simulation in Delta EC is higher than research before which is 9.4 W. Thus, it is proving that Delta EC software is possible in order to get the optimum value in design thermoacoustic heat engine for standing wave.
