水泵吸水池内流场的PIV试验分析

ANALYSIS OF PIV EXPERIMENTS ON FLOW IN A CLOSED MODEL PUMP SUMP

对一种新型封闭式吸水池及其改进设计（增加一个T形涡旋阻止器）的内部流场进行了PIV（粒子成像测速技术）试验测量,试验结果表明改进后的吸水池结构能够很好地避免和减少各种涡的发生,优化了吸水池内部的流动状态,从而提高了泵站的效率和性能。

PIV techniques are used to measure the flows in a model pump sump and an improving one with a T-type baffle. The experiment results are compared with each other. Then conclusion can be obtained that the model pump sump with a T-type baffle can reduce the occurrence of the vortex and improve the performance of the pump system.
