摘　　要：将叶片和蜗壳作为一个整体,采用边界元法对单流道泵内部三维非定常势流流动进行了数值模拟,计算了泵叶片表面压力,并在此基础上进一步计算了叶轮上所受的水力径向力及其变化趋势,对提高泵的运行稳定性具有指导意义。The impeller and the volute were viewed as a calculation field, the Boundary Element Method was adopted to simulate numerically the 3-D unsteady potential flow within the single channel pump. The blade surface pressure was computed. Furthermore, the radial force of impeller and its variation tendency were calculated, which is significant for enhancing the running stability of the pump.
