摘　　要：本文介绍了一种稳定性较高的混流式水轮机转轮流场准三元计算方法 ,该方法通过S1流面的积分方程法与S2流面的有限元法迭代计算得到转轮内部流态。同时以哈尔滨大电机研究所研制的某转轮为例进行了计算 。A stable quasi_3D calculation method of Francis runner flow field is shown in this paper, which is combined with the integrated differential equation method (IDEM) of S1 stream surface and finite_element method (FEM) of S2 stream surface to get the flow field of runner. An example runner designed by HILEM is calculated and the results are shown and analyzed in this paper.
