中文摘要	对某多级轴流压气机的其中两级的内部流场进行了全三维的CFD数值模拟,模拟结果与设计的级间参数比较吻合。通过对0.5倍设计间隙、1倍设计间隙和2倍设计间隙3个不同间隙的模拟结果的比较,探讨了间隙的大小对多级压气机总体性能的影响;通过内部流场的详细分析,揭示了间隙泄漏损失的特征。; The internal flow fields of two stages of a certain multi-stage axial-flow compressor have been numerically simulated with three-dimensional CFD.The simulation results agree relatively well with designed interstage parameter values.Simulation results of cases with three different tip clearances,of respectively 0.5,1.0 and 1.5 times that of the designed one,are compared with one-another.The effect of clearance size on the overall performance of the multi-stage compressor is discussed.By analyzing the internal flow field in detail,loss particularities due to tip clearance leakage are being disclosed.
