摘要
一、前言 为了降低损失、减轻重量,可控扩压叶型被越来越广地应用于压气机的设计。[1,2]提出了不同的方法进行可控扩压叶栅的设计。但是在设计中叶型往往是只按设计工况来设计选取的。这样设计得到的可控扩压叶型的变工况特性如何是令人十分关心的问题。为了得到变工况特性通常需要进行大量昂贵费时的叶栅吹风实验。
In order to reduce the losses and to improve the performance of compressors, the controlled diffusion airfoil cascade design has been widely used. Usually, a lot of experiments should be done to get the performance of the controlled diffusion cascade in on-degign and off-design conditions. Many efforts have been done in developing the CFD to partly instead of the expensive experiment work. Recently,a 2D N-S solver and a Viscous-Inviscid iterative code have been developed to study the controlled diffusion cascade flow in on-design and off-design conditions. The results are compared with experiment measurement.
