Abstract

An experimental method for visualizing the flow field within centrifugal pumps is presented in this paper. The working liquid used in experiments was a water-based multimolecular polymer solution in which polystyrol particles were added as the trace particles. A rotary-prism type high speed camera and a motion analyzer were applied to investigate the internal flow field of the pump on the line. The particle paths and velocity distribution in the flow field have successfully been obtained. It is naturally expected that this method can be used to give improvement in the design of centrifugal pumps, in which the separation and vortex intensity will be reduced, but efficiency raised.
