First, we investigated that the performance of axial flow pump can be improved by forced whirling motion (FWM). Although it is clear that FWM with the rotational ratio of 1 is the most effective for the pump performance improvement, its reason is not clarified yet. The internal flow of the pump was calculated with and without FWM for unsteady conditions to clarify the effects of FWM on pump performances. The CFD results revealed the differences in flow patterns between with and without FWM, and the estimation of distribution of shear speed around the impeller and on surface of it. The CFD results show that local downstream flows near the impeller are changed by the movement of the impeller with FWM. It was clarified that the pump flows and its behaviors contributed to the improvement in the performances of an axial flow pump using the FWM effect.

首先，研究了强制旋转运动对轴流泵性能的影响。虽然转速比为1的FWM对泵性能的改善最为有效，但其原因尚不清楚。在非定常工况下，分别计算了带和不带FWM的泵内部流动，阐明了FWM对泵性能的影响。CFD计算结果揭示了带FWM和不带FWM时叶轮流动形态的差异，以及叶轮周围和叶轮表面剪切速度分布的估计。CFD计算结果表明，叶轮的运动改变了叶轮附近的局部下游流动。阐明了泵的流动及其行为有助于利用FWM效应改善轴流泵的性能。
