摘要

以某1.5级高负荷轴流压气机为研究对象，采用经过校核的数值模拟手段详细探究了低雷诺数下表面粗糙度对其气动性能及内部流场的影响。结果表明：相比于光滑叶片，表面粗糙度为137.8时压气机性能提升最为明显，总压比、堵塞流量以及峰值效率分别提升4.01%、2.24%、5.34%。在整个表面粗糙度大小范围内，表面粗糙度布置在吸力面前缘至50%轴向位置时对分离、转捩的调控效果较好，能够较大限度地提升低雷诺数下压气机的气动性能。表面粗糙度通过促进转捩、抑制层流分离以及改变速度和静压分布来改善压气机流场和气动特性，同时一定程度上恶化了后面级的级间匹配关系，造成静子叶根处分离提前，角区分离加剧，限制了压气机整体气动性能的进一步提高。

Abstract

Numerical investigations were conducted to investigate the effects of the surface roughness on the aerodynamic performance of a 1.5⁃stage highly⁃loaded axial compressor under low Reynolds number conditions.Results showed that the highest aerodynamic performance improvement was achieved at surface roughness 137.8.The maximum increase in total pressure ratio，blocking flow，and peak efficiency was 4.01%，2.24%，and 5.34%，respectively.Detailed analysis showed that，within the entire region of surface roughness magnitudes，the surface roughness covering from leading edge to the 50% axial chord length on the suction surface had a relatively evident advantage to control the separation and transition，and the aerodynamic performance of compressor at low Reynolds number conditions was improved more distinctly.In general，at low Reynolds number，surface roughness can promote the transition，suppress the laminar flow separation，and change the overall magnitudes and distributions of the velocity and the static pressure，which improved the flow field and performance.However，it also deteriorated the incoordination between the subsequent stages，which induced a stronger corner separation in the aft stator，and limited the further improvement of the overall aerodynamic performance of the compressor.
