Abstract
A centrifugal pump is a pump which uses a rotating impeller for increasing the pressure of a fluid. Fluid flows to pump from the impellers hole and get accelerated by it and flows toward the volute fast from where enters to the outlet of the pump. Having enough knowledge in the field of geometrical parameters has a great effect on improving the designing and making this kind of pumps. The present study intends to take a small step in this field by evaluation of the effect of mentioned parameters and simulation of fluid current in inside the pumps. For reaching to this goal different number of blades in modelled in impellers and the performance of pump in simulated in Ansys CFX software and finally the results of CFD studies are presented as charts and curves.
