首先讨论了边界的离散单元、边界积分方程的离散方法和边界条件的给定,然后给出了计算实例,并把数值分析所预测的扬程与试验结果相比较,说明边界元法能较好地计算出螺旋离心泵叶轮中的流场。
Firstly, the discrete elements of the boundary, the discretization method of the boundary integral equation and the given of the boundary conditions are discussed. Then the calculation example is given and the predicted lift of the numerical analysis is compared with the experimental result. It shows that the boundary element method can well Calculate the flow field in the spiral centrifugal pump impeller.
