摘要
讨论了热声发动机在驻波和行波两种不同工作状态下, 其声功率产生的临界温度梯度与流道尺寸和工作介质的关系, 提出了基于行波工作模式的热声发动机新方案。
The paper compared the different working mechanism of thermoacoustic engines under traveling and standing wave modes,and discussed the dependence of critical temperature gradients of acoustic power generation rate on flow dimensions and working medium.A new scheme of thermoacoustic engine based on traveling wave mode was proposed.
