摘要

在低速条件下

对不同进口附面层厚度的大折转角环形弯曲扩压叶栅进行了实验和数值研究

分析了在不同厚度的进口附面层条件下叶片弯曲对扩压叶栅气动性能的影响.结果表明

相比实验进口附面层条件

当进口附面层较薄时

在多数冲角情况下采用正弯叶片对叶栅气动性能的改善程度都有所增大

而较大正冲角时

在较大折转角叶栅中采用较大弯角的正弯曲叶片仍然引起损失激增.

Abstract

The annular bowed compressor cascads with large camber angle under different inlet boundary layers thicknesses were investigated experimentally and numerically under low-speed condition.The effects of bowed blade on aerodynamic performance of compressor cascade were analyzed under different inlet boundary layer thicknesses.The results show that

when the inlet boundary layer is getting thinner

the aerodynamic performance of cascades improves under most flow conditions.However

the total loss will rise sharply if bowed blade with bigger incidences is adopted in the cascade with larger camber angle when the bowed angle is bigger.
