Abstract

In order to provide a set of validation data for a computational technique, an experimental investigation of the flow field at the exit of a centrifugal pump impeller was carried out. Measurements have been conducted at design and off- design flow rates. These data are compared to the results of a quasi-three dimensional computational technique. At design conditions, the two sets of data coincide well. While, at low flow rate the numerical model fails to give a prediction of the flow field. Introduction The flow in turbomachinery elements is one of the most complex flows. It's three-dimensional, viscous and unsteady due to the presence of fixed and rotating wheels. The actual testing of turbomachines, with detailed measurements in
