摘　　要：在离心压缩机叶轮上增设Gurney襟翼,采用CFD方法对叶轮进行气动计算,对比分析不同襟翼高度对叶轮流场的影响。结果表明,在叶片压力面增设Gurney襟翼,可以提高叶轮压比,襟翼高度在一定范围内可以提高叶轮效率。同时,Gurney襟翼也会对叶轮流场压力分布和相对马赫数分布产生一定的影响。A CFD method is used to compute the flow field of a centrifugal compressor impeller equipped with a Gurney flaps. The influence of the height of the Gurney flaps on the impeller flow field is analyzed. The numerical results indicate that the Gurney flaps have an influence on the pressure and relative Mach distribution of impeller. The pressure ratio of impeller increases with the Gurney flaps and the impeller efficiency also increases within a certain height range of the Gurney flaps.
