【摘要】 水泵吸水池内部的流动状态非常复杂 ,特别是在吸入管的周围 ,分布十分复杂的漩涡 ,这些漩涡的存在对整个系统的流动状态会产生众多的影响 ,有可能使泵站的性能恶化。为了研究吸水池内的流动状态 ,用 PIV量测技术对吸入管附近的流场进行量测 ,并对测量结果进行分析 ,进而得到测量面上的湍流特征更多还原

【Abstract】 The flow conditions in the pump suction sump are very complex, there are kinds of vortices in and around the pump bell, these are common problems, which lead to poor pump performance. PIV technologies are used to measure the flow conditions in the model of pump suction sump, and the data of the experiments are analyzed to obtain the characteristic of the turbulence on the measurement planes.更多还原
