Abstract

This paper deals with the aerodynamic shape optimization of the return channel for a multi-stage centrifugal compressor. Utilizing the 3 dimensional Computational Fluid Dynamics, CFD, and automated optimizer, optimal geometry of return channel is investigated. Through this optimization process, the aerodynamic loss and de-swirl performances are much improved. The method how to design the return channel with high performance is also discussed in this paper.
