The effects of parameters such as the gascompressibility, the liquid viscosity, surface tension, density ratio , and velocity ratio, have been considered.
A performance prediction model is established in this paper which taking ac count into gascompressibility and the change of cross section area of flow channel.
本文建立的性能预测模型考虑了气相的可压缩性和沿流道的截面面积的变化,介绍了数值模拟的方法和步骤。

But due to the compressibility of gas significantly higher than fluid, the state equation of gas is different from fluid.
