摘要
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。
Numerical simulations on a tow stages turbine with bowing blade of different types of stacking lines were curried out. An improved stacking line was presented and flow field in the blade passage was discussed. The results show that the shape of the stacking line has a great influence on the performance of turbomachinery, the optimum blade angle of the cascades varied with different shapes of the stacking lines.
