摘要(Abstract)：

利用激光成像速度仪 (PIV)测量了旋转离心叶轮内部的非定常流场。通过对实验数据的进一步处理 ,获得了旋转离心叶轮内部相对速度的非定常流场分布。详细分析了叶轮内部非定常流动现象和流动规律。通过实验研究发现 ,旋转离心叶轮内部的流动是非定常的 ;在叶轮出口处 ,叶片的吸力面与轮盖的夹角区存在一个低速区 ;并观察到了明显的射流 /尾迹结构。射流区和尾流区的大小和范围在沿盘盖方向和跨叶片方向上是不同的 ,射流区和尾流区之间不存在明显的分界线
Unsteady flow in centrifugal impeller has been measured by mean of PIV.The analyses of experiment results in jet-wake flow have displayed the flow structure in outlet of impeller,especially clearly revealed many compicated phenomena in flow field.The size and strength of jet-wake flow structure in outlet of impeller was change with time.The apparent dividing line between jet and wake zone is not be existed.
