Numerical Study of the Influence on Flow in Impeller with Different Diffusers

Haiyan Wu

Abstract

A centrifugal compressor stage model is numerically studied.The result agrees with the experiment result.A numerical simulation is preformed by replacing vane diffuser with vaneless diffuser with the other boundary conditions unchanged.The flow conditions in impeller are analyzed in order to study the influences of vane diffuser and vaneless diffuser on flow field of a centrifugal compressor.
