本文利用 PIV 技术测量了卧式开放式水泵吸水池内部台阶附近的流场,得到了定常不同工况下的流场速度分布图等水力参数结果,通过对试验结果的分析发现,台阶高度、进口来流速度和淹没深度的变化对吸水池内部流场都产生重要的影响.
The whole flow field near the step in the open sump is measured with PIV system. The distributions of speed are obtained in all steady flow operation. According to the analysis of the results, it is found that all the factors including the height of step, the velocity of fluid flow and the water depth influence the flow situation in the open pump
