摘要：

A theoretical and experimental study has been made on the transient characteristics of a centrifugal pump during its rapid deceleration from initial speed to zero. Instantaneous rotational speed, flow-rate, and total pressure rise are measured for various stopping schemes. Theoretical calculations for the prediction of transient characteristics are developed and compared with the corresponding experimental results. As a result of this study, it becomes clear that impulsive pressure and the lag in circulation formation around impeller vanes play predominant roles for the difference between dynamic and quasi-steady characteristics of turbopumps. Moreover, a criterion for the assumption of quasi-steady change is presented.
