一、引言 本文是一种尝试,企图运用已有的试验资料及理想流体准三元流动理论设计出具有较高气动性能,便于制造的径、混流式三元叶轮.W.Jansen提出了一种很好的离心式压缩机叶轮叶片的设计方法.他把叶轮叶片的设计分成二大步.第一步,根据设计要求 I. INTRODUCTION This paper is an attempt to design a radial and mixed-flow ternary impeller with high aerodynamic properties by using the existing experimental data and ideal fluid quasi-ternary flow theory. W. Jansen proposed a Very good design of centrifugal compressor impeller blades. He divided the design of the impeller blades into two steps. The first step, according to design requirements
