水力机械内部流动计算的一种新奇点法

A New Singularity Method For Flow Analysis in Hydraulic Machinery Runners

提出了一种适用于奇点法解水力机械内部流动的进口边界条件给定方法，建立了直接解离散点涡方法计算薄翼平面环列翼栅的数学模型和算法，开发了相应的计算程序。实例计算结果与流场可视化实验结果对比分析表明，给出的方法较准确地描述了设计工况时叶栅进、出口的流动状态。

Using singularity method,A new decision for the inlet boundary conditions of hydraulic machinery is proposed,and then new model and algorithm presented,corresponding program developed.The comparison between a test calculation results and flow visualization results shows that the inlet and outlet flow of the runner can be more accurately described with this method.
