摘要
本文提出了一种计算离心泵叶轮内部流动和性能的势流一边界层迭代解法。势流计算采用表面奇点分布法,可以准确地反映叶片形状对流场的影响;三元边界层计算采用积分法,可以考虑边界层内部的二次流。
An iterative method has been developed for computing an internal flow and performance of a centrifugal pump impeller. The method consists of combining a integral method for a three-dimensional boundary layer on the whole channel wall with a surface singularity method for an inviscid core flow. The influences of blade shapes of the impeller and secondary flow in the boundary layer on the internal flow field are, therefore, taken into account more accurately in this method.
