| Abstract: | The internal flow of a centrifugal impeller and casing is numerically simulated based on FLUENT6.3 Software Platform,standard turbulence model and SIMPLEC algorithm.The information of flow fields at different operating points is obtained through difference analysis of internal flow.It can be concluded that the results are able to provide important guidance for the hydraulic design of centrifugal pump and its optimization. |
