摘　　要：在泵系统轴向涡流的测试计算基础上 ,用离散涡方法计算涡系位置的演化 ,模拟泵系统入口涡量场的轴向涡流运动 ,通过数值计算得到系统涡量场的涡线。模拟计算结果与实验测试结果基本吻合 ,为泵系统流体力学特性研究提供了新方法。On the basis of the experiments and computations of axial vortex in a pump system, the trajactory of vortex movement was computed with the mechod of discrete vortex and the axial vortex movement in the inlet side of the pump system was simulated. The vortex filament was got by the numerical method. Under the circumstances of identical vorticity, the transient continuously distributive vortex can be replaced by a number of discrete point vortexes. The results of the experiments were well coincident with those from the simulation method which provided a new way for hydromechanical characteristics of a pump system.
