摘　　要：介绍了准正交面法, 并将该方法应用于水轮机转轮的三元流场计算中, 建立了准正交面法计算三元流场的数学模型, 且给出了准正交面法迭代求解的总步骤, 从而为水轮机转轮的设计探索了一条新的途径.The quasi-orthogonal surface method and its application to 3D Calculation of the flow field throughwaterturbine runner are presented. The mathematical models for calculating 3D flow field by this method arederived and the general steps to solve alternately the equation by quasi-orthogonal surface method are described.Thereby, an exploration is made into a new design method for runners.
