热声发动机（TAEs）可用于使用声波泵送热量或使用温度梯度泵送声波。基本安排是一个充满气体的声学谐振器，并适当放置热声元件。在这些发动机中使用了两种类型的热声元件：(1)用于在气体和外部热源之间传递热量的热交换器；(2) TAE，也称为堆栈。tae是支撑温度梯度的多孔介质部分，在交换器之间传递声波上的热量，并产生或吸收声功率。先前的结果已经发展为具有圆形或平行狭缝孔隙几何形状的TAEs。将该理论推广到含气TAEs，使其包括任意截面几何形状的孔隙。给出了热声原动机的能量流近似分析和声学测量结果
Thermoacoustic engines (TAEs) can be used to pump heat using a sound wave or pump a sound wave using a temperature gradient. The basic arrangement is a gas-filled acoustic resonator with appropriately positioned thermoacoustic elements. Two types of thermoacoustic elements are used in these engines: (1) heat exchangers used to communicate heat between the gas and external heat reservoirs; and (2) the TAE, also known as a stack. The TAEs are sections of porous media that support the temperature gradient, transport heat on the acoustic wave between the exchangers, and produce or absorb acoustic power. Previous results have been developed for TAEs with circular or parallel slit pore geometries. The theory is extended for gas-filled TAEs to include pores of arbitrary cross-sectional geometry. An approximate analysis of energy flow and acoustical measurements of a thermoacoustic prime mover are given.>
