本文应用Ｓ２流面正问题计算方法和三维Ｅｕｌｅｒ方程的时间推进计算方法对某涡轮弯扭静叶栅流场分别进行了分析计算，并在环形涡轮叶栅实验台上测试了该叶栅出口截面上气动参数的分布。通过分析、比较计算结果和实验数据，既考核了算法，也研究了弯扭静叶栅中的流动机理，由此得出了对弯扭叶片的气动设计计算具有重要意义的几点结论。
In this paper, the flow field of a turbine cascade was analyzed and calculated by applying S2 flow surface positive problem method and 3-D Euler equation time advance calculation method respectively. The outlet section of the cascade was tested on a ring turbine cascade test bench On the aerodynamic parameters of the distribution. By analyzing and comparing the calculated results with the experimental data, we not only evaluate the algorithm, but also study the flow mechanism in curved and torsional cascades, and draw some conclusions that are important to the aerodynamic design and calculation of curved and twisted blades.
