摘　　要：基于三维非定常欧拉方程和三维激盘模型发展了一种用于研究轴流压气机动态失速过程的三维计算方法.利用该计算方法研究了某型高压压气机第一级的动态失速过程,并就转子总静压升特性的三种不同径向分布对失速过程的影响进行了分析.计算结果表明该方法能够反映出压气机的三维动态失速过程、失速团的三维空间结构,并能有效地表现出转子沿径向的特性变化对压气机气动稳定性的影响,而且还能够用于判断压气机的危险截面.A 3-D dynamic stall inception analysis method was developed based on the 3-D unsteady Euler equations and the 3-D actuator-disk model.The stall inception of the first stage of a high compressor was studied using this method.The compressors were designed using 3-D method,showing that the characteristics of the rotor are different in the radial direction,so three different static-to-total pressure ratios of rotor were studied in this paper,and the effects on the stall inception were investigated.The results s...
