Abstract

centrifugal pumps are used in the various industries as one of the important components responsible for the movement of the incompressible fluids. In this paper, the fluid flow of water in a centrifugal pump is simulated with a three-dimensional numerical solution. The operating fluid is considered to be incompressible and in steady state condition. The numerical solution is performed using a ANSYSY 16. 0 software. The provided results are validated by the pump manufacturer's characteristic curves. One of the effective factors in increasing the efficiency of the centrifugal pump impeller is the change in radial distribution of surface centers of two-dimensional profiles. In this research, these changes have been done in tangential direction. The change of the lean angle in two modes of fixed hub and fixed shroud has been performed. The simulation of the flow field for various lean angles showed that the creation of a negative lean angle has been increased the efficency by 0. 51% for the fixed hub and 1. 34% for the fixed shroud.
