Aspects regarding the centrifugal pump operation

Résumé

The centrifugal pumps are part of hydrodynamic units that enable the power transmission to the working fluid. These pump types are converting the mechanical energy taken from an external motor into kinetic energy characterized by fluid mass flow rate and flow velocity. A centrifugal pump assembly having three impeller models have been designed and analyzed with ANSYS CFX in order to highlight the fluid flow characteristics through the pump body and how the impeller geometry influences the centrifugal pump working process. The results are presented in terms of fluid flow velocity and pressure for each analyzed impeller model.
