| Abstract: | The flow in the centrifugal pump im- peller directly affects the pump＇s characteristic pa- rameters, such as the pump＇s head and efficiency. Flow field can be measured accurately and undis- turbed by using PIV（particle image velocimetry）. In the experiments, the PIV was used to measure the flow field in the centrifugal pump, the velocity distribution was obtained, and the inner flow in the centrifugal pump was preliminarily mastered under different working conditions. |
