| Abstract: | The charaeteristies of low specific speed centrifugal pump are introduced, and the grid generation method for impeller passageway and the governing equations of calculation are also expatiated. Using commercial CFD software FLUENT for different blade forms in the impeller passageway, 3D turbulent flow is calculated. Based on Reynolds average, the RNG k-e model, and SIMPLEC are used for the calculation. The optimal design level of low specific speed centrifugal pump is improved through analyses of the influences of blade forms of impeller on the velocity distribution, the pressure distribution and the inner flowage rules of the pump. |
