摘　　要：文章以S_1、S_2流面理论为基础,对实际流动进行平均化处理,建立起混流式水轮机转轮的一种准三元设计方法。S_2流面采用有限元计算,S_1流面采用积分法计算。该设计方法不仅考虑了连续方程和叶片微分方程,还考虑了水流的运动方程,使计算出的轴面流场更符合实际情况,从而可提高水轮机转轮设计的命中率。以该方法为基础所开发的混流式转轮准三元设计系统,成功地应用于水轮机转轮设计,表明该设计方法是实用和有效的。Based on S1 . S2 flow surface theory, the quasi-three dimensional method to Francis runner is established by averaging of actual flow, in which S1 flow surface adopts integral calculation and S2 flow surface adopts limited dimensional calculation. The design method considers not only continual but also calculus equation, as well as motive equation of flow, so the calculated axial surface flow is more closer to actual flow and design accuracy is increased. This design system has proved to be practical and effective for its successful application in Francis runner design for Three Gorges Project.
