This paper is aimed at analyzing the hydraulic performance characteristics of a laboratory centrifugal pump impeller for which many experimental data are available in the open literature. The detailed flow field in the pump impeller and its performance curves are investigated by the validated commercial computational fluid dynamics (CFD) code adopted in the present study. Predicted performance characteristics agree very well with the test data at the nominal and partial flow rate conditions. The performance analysis method presented herein can be effectively used as a tool for the hydraulic design optimization and assist in the understanding of the operational characteristics of centrifugal pump impellers.
