Optimization of centrifugal compressor stages

Abstract

The article describes а hydraulic efficiency increase in the centrifugal compressor stage using automatic optimization algorithms. The optimization criterion is the polytropic efficiency of the intermediate compressor stage. The sequence of stages of the optimization process in the Fine/Design3D software module of the Numeca software package is presented. The creating process a solid model of the compression stage is shown. The performance curves of the developed stage after optimization of the shape of the rotor and stator elements are also presented.
