Abstract：According to peculiarities of the geometry of the centrifugal pump impeller and its inner flow field, method for the grid generation impeller’s passage and the governing equations for calculation of flow field are briefly represented. Based on RANS Equation, SIMPLEC algorithm, the RNG κ - ε model and wall function, the 3-D turbulent flow in the impeller is studied. Results show that the distorted blade profile of centrifugal pump can exert much influence on pressure distribution, velocity distribution and pump抯 performance. This method can be use to improve level of optimization design for the centrifugal pump and check its internalf lowf ield condition.
