Abstract: An evaluation of the torque on an impeller blade interacting with a diffuser blade is presented. Comparisons of time averaged quantities are made between computed and measured results. The ...

Abstract: Hysteresis in a pump characteristic results from instability phenomena involving complex three dimensional flow with recirculation. The unsteady flow field on the top and bottom branches of a ...

Abstract: An experimental investigation is presented regarding the unsteady pressure field within a high specific speed centrifugal pump impeller (ωs = 1.7) which operated in a double spiral volute. For ...
