The development of computational fluid dynamics has successfully contributed to the prediction of the flow field through pumps and the enhancement of their design. In the present analysis a double-arc synthetic blade design method is proposed for the optimum hydraulic performance of a centrifugal pump. The one-dimensional Pfleiderer's approach based on empirical analytical equations is applied for the main geometrical characteristics of the pump impeller. The numerical solution of the discretized three-dimensional, incompressible Navier-Stokes equations over an unstructured grid is accomplished with a commercial CFD finite-volume code. The characteristic performance curves are resulted through the calculation of the internal flow field. For every double-arc blade design method, the pressure distribution of the pump is computed and the velocity field between the blades at the leading edge and in the region of the tongue is studied.
