Abstract

Performance of a regenerative pump is evaluated based on the calculated through flows using the CFX-TASCflow code. Flow calculations are performed in one vane to vane space of the impeller and side channel. The flow is very complex three dimensional with a strong radial vortex due to centrifugal force and an axial vortex due to re-circulating flow between the impeller and the side channel. Momentum exchange on the plane between the impeller and the side channel are evaluated to estimate design parameters and viscous losses in the pump. The present study contributes to showing the capability of flow simulation of complex flow in the regenerative pump by comparing the calculated performance with the measured value.
