摘　　要：以减弱轴流压缩机静叶角区分离为目的,将非轴对称端壁造型技术引入轴流压缩机的设计中。数值模拟结果显示,设计的非轴对称轮毂使原型压缩机静叶根部的角区分离显著减小,级工作效率得到提高。The technique of non-axisymmetric endwall profiling is introduced into the design of axial-flow compressor for the purpose of diminishing the comer separation occurred in the datum design. The result of numerical simulation shows that the designed non-axisymmetric hub can make the comer separation in the root of stationary blade of prototype compressor decreased significantly and the operating eflqciency of stage improved.
