摘　　要：本文将边界元法用于混流式水轮机导流叶栅流场的数值计算,提出了将Kutta条件引入边界元方程求解的直接法,避免了通常需要的迭代过程,提高了计算效率。编制的计算机程序可用于计算固定导叶与活动导叶不同排比的流场。计算结果是令人满意的。In this paper, the boundary element method is used to calculate the flow field around the guide cascades of a mixed flow turbine. A direct method by which the Kutta-Condition can be substituted into the BEM equations is presented. So the iterative procedure usually used tan be avoided and the computing efficiency is raised. A computer program is developed to calculate the flow field around the guide cascades with arbitrary ratio of stay and guide vanes. The results of calculation is considerable.
