离心压气机叶轮设计方法研究进展

Centrifugal Compressor Design Methods Progress

对离心压气机设计方法进行了总结。把离心压气机设计方法划分成几何设计方法和气动设计方法,认为几何设计方法正在逐步被气动设计方法所代替;对目前工程实际设计中使用的离心压气机计算机辅助集成设计系统所包括的各子系统及其相互关系进行了总结;对最近二十年内出现的全三维设计方法进行了简要介绍;并且对离心压气机设计中可能出现的新方法进行了展望。

The objective of this paper is to review the development of centrifugal compressor design methods. The design methods of centrifugal compressor are divided into aerodynamic and geometry design methods. The aerodynamic design method is replacing the geometry design method step by step. The progress about the computer-aided turbomachinery design system that integrates aerodynamic and structural a-nalysis for a centrifugal compressor is also summarized in this paper. The 3D inverse design method presented in the last twenty years is described briefly. Finally, some new design methods being used in the near future are indicated.
