| 摘 要： | 高压比离心压缩机正在喷气发动机和燃机中得到越来越多的应用。然而,人们对其流道内三维粘性流动的认识却非常有限。本文基于已经过实验数据确认的CFD结果,详细地分析和讨论了一种高压比离心叶轮内在近设计点的三维流场,以揭示其中激波与边界层相互作用和二次流动结构等的特征。

| Abstract: | High speed centrifugal compressors have been increasingly used in small aero-engines and gas turbine industries.However,knowledge of the 3D viscous flow in this kind of impeller flow passage is quite limited.Based on the CFD results validated previously with experimental data,this paper analyzed and discussed in detail the 3D flow within a high-speed centrifugal impeller at near-design condition in order to make deep understanding of the features of shock/boundary layer interaction and its secondary flow pattern. |

| Keywords: | aerospace propulsion system centrifugal compressor shock and boundary layer interference secondary flow |
