Abstract

The present paper describes an experimental and numerical investigation of a radial flow pump impeller with 2D curvature blade geometry. Investigation of the behavior of the above impeller for a wide flow rate range and for various rotational speeds was carried out and the obtained experimental results were validated with available measurements of the same impeller within spiral casing.
