Abstract The vortex pump of type 80X-13.5 was numerically simulated. The inner flow model was designed by Pro/E.Separated unstructured hexahedron grid partition and part of boundary condition were used by Gambit.Considering Reynolds Average N-S Equation and standard k-ε turbulence model with SIMPLEC algorithm,numerical simulation for the three-dimensional steady incompressible turbulent flow of the vortex-pump was carried out.The medium is water and the inner flow field of vortex pump is rotating flow with constant angular velocity,three dimensional,and incompressible turbulent flow.The distribution of velocity and total pressure were obtained in numerical simulation.The distribution area of flow are summed up.The circumferential flow is considered as the main flow and can be divided into run-through flow and circulatory flow.The result of numerical simulation testified the validity of the existing model and the new division of flow distribution of the vortex pump typed 80X-13.5.vortex-pump;numerical simulation;flow mechanism;pressure distribution;run-through flow;circulatory flow
