摘要

通过采用五孔探针在低速平面风洞上测量压气机叶栅流场的方法

研究了不同高度和周向位置的端壁翼刀对叶栅能量损失及二次流速度矢量的影响.结果表明

使叶栅总损失降低的最佳周向安装位置是距离吸力面70%相对节距处

最佳翼刀高度为5 mm;存在使叶栅总损失降低的极限翼刀高度.当翼刀高度增加时

翼刀涡更加清晰.安装翼刀可以改变叶栅端壁损失的分布

进而控制吸力面/端壁角区的流动

改善叶栅的气动性能.

Abstract

Through measurement of the compressor cascade flow field by using the five-hole probe in a low speed wind tunnel

the effect of the different height and circular locations endwall fences on the total cascade loss and secondary velocity vectors was investigated.The results show that

the optimal circular location of fences which decreases the total cascade loss is 70 percent of pitch far from the suction surface of the blade

the optimal height of fences is 5 mm;the height of fences which decreases the total cascade loss is not unlimited.The endwall fences vortices became distinct with the increasing height of fences.The distribution of the cascade endwall loss can be changed by fences

so the flow in the corner of the suction surface/endwall is controlled and the aerodynamic performance of the cascade is improved.
