摘要
本文以1/4πr为基本解，采用直接边界元法求解混流式转轮内的全三维势流流场。并对HL220转轮流场进行数值模拟计算，结果表明此法是进行三维流场计算的有效方法。
With1/4πr as the basic solution,fully three dimensional potential flow field in Francis runner is solved by the direct BEM in this paper.At the same time calculation of the numerical simulation is carried out on the flow field of HL220 runner.Its result shows that BEM is effective on the calculation of three_dimensional flow field.
