OPTIMIZED REDSIGN OF THE CENTRIFUGAL PUMP IMPELLER BASED ON NUMERICAL ANALYSIS OF 3D TURBULENT FLOW

Abstract

Abstract: The standard k–e turbulence model and the wall function are adopted to solve 3D turbulent flow field in the impeller of a centrifugal pump. The influences of the blade profile on speed distributions, press distributions and pump performance are analyzed. The flow regulation pattern in the impeller of a centrifugal pump is also investigated. A redesign and optimiz-ing method of the impeller blade profile based on numerical analysis of 3D turbulent flow is put forward. The results show that the proposed method is a very outstanding tool to carry out the redesign and optimizing of the impeller blade profile.

Key words: 3D turbulent flow, Centrifugal pump, Impeller, Numerical analysis, Optimized design
