摘　　要：本文对混流式水轮机中固定导叶和活动导叶组成的双环列导水叶栅的流动进行了计算。计算采用了非线性的二维奇点分布法。作者在文中推导了求解的数学模型,并把计算结果和实验值进行了对比。结果表明,本文提出的方法具有较高精度,其计算结果和实验值取得了较好的一致。This paper presents results of experimental and theoretical studies on the flow through the double circular cascade consisting of stay vanes and guide vanes for a Francis turbine.Theoretical calculation was carried out by using the 2D singularity method. The mathematical model was for mulated and results of calculation were compared with the results of experiments which shows very good agreement.
