Abstract

This paper presents electrodiffusional measurements of the wall shear rate at the impeller surface of a radial centrifugal pump. Twelve probes of different radii and at different positions along one blade were used in a pump with an open six bladed impeller. By means of throttling and speed control the operating point of the pump was adjusted and the influence on the wall shear rate was studied. The measurements were related to the analytical solution for a free rotating disc and the shear gradients were in the same order of magnitude.
