摘　　要：用主流区无粘性流动与壁面边界层迭代的计算方法预测混流泵叶轮和导叶内的三维粘性流动，在无粘流和边界层的计算中分别用准正交面法和动量积分法进行计算。该方法计算速度快，易收敛，较适于优化设计中的流场分析。An analysis of the viscous flow is made with the iterative computing method for the po-tential flow-boundary layer.The calculation of the potential flow is carried out with themethod of quasi-orthogonal plane and that of the boundary layer with the momentum inte-gration equation. The method proposed is found to have a high calculating speed and rate ofconvergence. Hence it is suitable for performance prediction and optimization design.
