Abstract

Centrifugal compressor is the vital part of many mechanical systems. The present paper deals with the simulation and the analysis of the fluid performance in two subsonic compressor stages under different rotational speed. The configurations used for the study is two subsonic centrifugal compressors with 60mm and 70mm diameter impeller wheels respectively. Numerical simulation is carried out with CFD (Computational Fluid Dynamics) techniques which solve the Navier-Stokes equations on the fluid performance inside stage. The simulation shows the two stages at 8,000 rpm and 10,000 rpm of the rotor speed, respectively. Particular emphasis is laid on the comparison of operational range and flow characteristics on different stages and operation speed.
