Description: This paper presents the numerical investigation of the 3D multiphase flow in the impeller of a centrifugal pump from a pumping station by using commercial code FLUENT 6.3. The storage pump has five blades and it is operating at a certain flow rate with a given rotational speed. The computational domain represents only one inter blade channel of the impeller and was generated using the pre-processor GAMBIT from FLUENT, based on the existing geometry. A steady relative 3D multiphase flow is computed in the 3D computational domain and the numerical solution of flow equations is obtained with the expert code FLUENT 6.3, using a Reynolds-Averaged Navier-Stokes (RANS) solver. In order to solve the multiphase flow, the mixture model of the solver is used.
