In this paper shows a numerical simulation of the three-dimensional fluid flow inside a centrifugal pump. For these numerical simulations the SIMPLEC algorithm is used for solving governing equations of incompressible viscous/turbulent flows through the pump. The k-ε turbulence model is adopted to describe the turbulent flow process. These simulations have been made with a steady calculation using the multiple reference frames (MRF) technique to take into account the impeller- volute interaction. In this study, the viscous Navier-Stokes equations are used to simulate the flow inside the vaneless impeller and volute Computational fluid dynamics (CFD) analysis is being increasingly applied in the design of centrifugal pumps. With the aid of the CFD approach, the complex internal flows in water pump impellers, which are not fully understood yet, can be well predicted, to speed up the pump design procedure. A solution method is developed to obtain three-dimensional velocity and pressure distribution within a centrifugal pump. The method is based on solving fully elliptic partial differential equations for the conservation of mass and momentum
