用求解Ｓ２流面平均Ｅｕｌｅｒ方程组程序对一个两级涡轮进行了数值模拟，静叶采用弯叶片，且采用了不同的积叠线生成方式；用高精度三维ＮＳ方程求解软件对第一级静叶进行了不同弯曲方式的数值模拟，分析了不同积叠线生成方式对涡轮性能的影响。
A two-stage turbine is numerically simulated by solving the S2 flow surface average Euler equations. The stator blades are bent blades, and different stacking line generation methods are adopted. The software of the first-order static The numerical simulation of different bending modes was carried out and the influence of different stacking line generation modes on turbine performance was analyzed.
