摘　　要：　水下高速可压缩气体射流的两相流计算不易收敛,本文提出按水的密度设计一种理想气体,然后与燃气一起按两相气体混合流进行计算取得成功。这一办法对一相基本静止的情况时实用的。It's very difficult to get computation convergence for the mixing of two-complex-phase flow. The article devotes to design a special' ideal gas'to simulate the water and transfer the problem into the mixing of two pure gases flow and got computation convergence. This method would be useful for the cases where the incompressible phase is essential steady.
