| 摘 要： | 在自行开发的以一元流动理论为基础的透平膨胀机性能预测方法的基础上，经过推导，获得了透平膨胀机使用同种工质时的决定性相似准则，即特性比、膨胀比及叶轮进口圆周马赫数中的任意两个，为组织同种工质的模化试验，也为进一步研究透平膨胀机使用不同种工质时决定性相似准则的选取奠定了基础。

| Abstract: | The decisive similarity criteria of turbo expanders were deduced based on an one dimensional analysis of expansion turbines developed by us.These decisive similarity criteria are two of three variables:the velocity ratio 1 ,the expansion ratio p 0/ p 3,and the peripheral Much number at the inlet of working wheel Mu 1 .This paper is useful for organizing the modeling tests using the same working fluids and selecting the decisive similarity criteria using different ones. |
