Multistage Compressor Design Based on Dimensional Zooming

Abstract

This paper proposed an axial multistage compressor aerodynamic design methodology based on dimensional zooming. Two-dimensional design parameters are acquired through the dimensionality reduction of three-dimensional data to avoid dependence on the empirical loss models. The research on the zooming design method is conducted on a self-designed five-stage compressor. The method has considered the three-dimensional end wall viscosity loss and modified the blade profiles and blade stacking. It provided a path on how to improve the blade design based on computational fluid dynamics analysis. The aerodynamic performance, compressor characteristics of the prototype, and the zooming design are investigated and compared. The results show that the zooming design compressor performances are improved than those of the prototype one.
