摘　　要：　本文对单流道泵的物理模型进行简化,建立了二元单叶片泵内部流动解析的数学模型,采用势流边界元解法,数值模拟了泵内流动,并计算出单叶片泵的水功率,与试验结果进行比较,间接证明了计算方法的可行性。Based on the simplification to the physical model of single channel pump, a analytical mathematical model of internal flow in twodimensional single vane pump was set up. The boundary element method (BEM) of potential flow was adopted to simulate numerically the internal flow in pump. In addition, the water horsepower of single vane pump was calculated and compared with the experimental results. The results show indirectly that the boundary element method (BEM) was feasible.
