Efficiency Optimization of a Standing-Wave Thermoacoustic Heat Engine : Basic Concepts and Case Study (2013. 180 S. 220 mm)

§16§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 〓16§ mm-thick-plates, spaced by 0.648 mm, giving a porosity ratio of 0.68067, will theoretically convert heat to acoustic power at an efficiency of 30.611% which is equivalent to 47.97% of Carnot's efficiency.
