摘  要:
建立了试验装置,测试了旋流泵叶轮流道内轴垂直断面上的速度分布和叶片表面压力分布,并建立了计算旋流泵叶轮内流动的流动模型,提出了旋流泵叶轮内流场的全三维边界元解法。将计算结果与试验结果对比得出,计算速度场与测试结果的趋势是一致的,叶片表面压力的计算值与测量值吻合良好。

摘  要:
The authors investigate the inner flow within the vortex pump impeller. Starting with the measured inner flow field within the impeller and pressure on the blade surfaces never touched by the previous researchers. And in cooperation with the measured results of inner flow within the chamber obtained by other researchers, a flow pattern is established and used to calculate flow field within the vortex pump impeller. As application of boundary elements method to its calculation) a method is suggested for calculating the fully three-dimensional potential flow field within vortex pump impeller. A comparison of the calculated and measured results showing the same tendency between calculated and measured results of velocities, and a good agreement between calculated and measured values of pressure on blade surfaces.
