通过求解由粘性力引入损失的Ｅｕｌｅｒ方程，模拟了某型两级双轴涡轮的内部稳态流场。计算采用了变比热容，用“混合平面法”对叶列间的相互干扰进行了处理，结果表明总体参数的计算值与发动机试验相吻合。 By solving the Euler equation of loss introduced by viscous force, the internal steady-state flow field of a two-stage two-stage turbine is simulated. The calculation of variable heat capacity, “mixed plane method” to deal with the mutual interference between the leaf columns, the results show that the calculated value of the overall parameters and engine tests are consistent.
