| Abstract: | IS80-65-160 pump was investigated,by using computational fluid dynamics software FLUENT.The standard k-ε turbulent model,the SIMPLE algorithm and the multiple reference frame were applied to simulate the three dimensional flow in the centrifugal pump at design and off-design conditions.The internal flow and the external performances of the centrifugal pump were analyzed.The partition method of the steady performance curve was proposed. |
