| Abstract: | Based on the reynolds time-averaged Navier-Stokes equations and the standard k-ε model,the simple algorithm with multiple reference frame coordination was applied to the analysis of three-dimensional turbulence flow in a IS80-50-315 centrifugal pump by means of Fluent.The pressure and velocity distributions at different flow rate were obtained.The effect of flow rate on operational performance of the centrifugal pump was also investigated.The present work is helpful to the design of this kind of centrifugal pump. |
