The thermoacoustic engine is a device that converts heat energy into sound or acoustic power. They are used currently to recover waste heat from military vehicles and converting it to electricity, which means that such devices can play a significant role in power generation for domestic & commercial purposes. This study demonstrates an attempt to design a 1-meter-long thermoacoustic heat engine with optimum efficiency. This will be done using DeltaEC, a software which was developed especially for the modeling of low amplitude thermoacoustic devices. The optimization process includes...
