A 3-D simulation of flow in a screw-type centrifugal pump with tip clearance

摘要

The present paper describes a three-dimentinal numerical simulation of internal flow of a screw-type centrifugal pump with tip clearance, which has much influence on the pump performance. A reliable commercial three-dimensional Navier-Stokes code (CFX-TASCflow) with a standard k-epsilon two-equation turbulence model has been used in this study.
