摘要: 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。

Abstract: The internal flow field of a two stage turbine with double shafts was simulated by solving the steady Euler equation with loss model. The varying specific heat was considered because the range of temperature in multistage turbine was very wide. The interaction between the stator and the rotor was dealt with the method of “mixing plane”. The results show that the total parameters agree well with the experiments, The internal flow field is shown in detail.
