Study on the Onset Temperature Difference of Thermoacoustic Stirling Prime Movers

热声机械作为一种新型的能量转化装置 ,讨论其起振温差对于利用低品位能源具有非常重要的意义。文中讨论了行波型热声发动机起振温差的计算方法 ,得到了回热器结构、工作介质、丝网。

The onset temperature difference of thermoacoustic Stirling prime movers is a very important parameter for utilizing low quality heat energy. This paper establishes an analytical model for calculating the onset temperature and some dependence of the onset temperature difference on the length and porosity of the regenerator, the working gas, the frequency, the pressure if other thermodynamic elements of the prime movers are given.
