摘要

针对压气机静子角区分离产生堵塞的现象

开展了静子轮毂修型的研究.通过对实例静子不同方案的数值模拟

验证了轮毂修型可以有效的抑制角区分离

从而降低轮毂区域的堵塞.其中

对实例静子根部分离点处进行的轴向轮毂修型

可以使静子叶栅出口的堵塞量降低20.4%

静子10%叶高处总压恢复系数从原来的0.89提高到0.948.

Abstract

After analyzing the mechanism of the end wall blockage from stator corner flow separation in compressor

the hub-shape contouring was presented in this paper.The RANS(Reynolds-averaged Navier-Stokes) numerical calculations of real cases of compressor stator show that modifying hub shape can depress efficiently the corner flow separation so as to decrease end wall blockage.Subsequently

the corner blockage of the outlet of stator cascade was decreased by 20.4% and the total pressure recovery coefficient of 10% blade height was increased from 0.89 to 0.948 by the concave profile near the separation point of stator end wall.
