项目摘要

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，我们研究了强迫旋转运动（FWM）可以提高轴向流动泵的性能。尽管很明显，旋转比为1的FWM对泵的性能提高最有效，但尚未阐明其原因。对于不稳定条件的情况，用有或没有FWM计算泵的内流，以阐明FWM对泵性能的影响。 CFD结果揭示了有和没有FWM之间的流动模式的差异，以及叶轮周围和表面上剪切速度的分布的估计。 CFD的结果表明，叶轮附近的局部下游流通过叶轮使用FWM的移动而改变。澄清说，泵流及其行为使用FWM效应有助于轴向流动泵的性能改善。
