| 摘 要： | 本文对一台带有不同周向进口畸变装置的三级、低速、轴流压气机进行实验研究。研究结果发现周向进口畸变对压气机失速过程的影响包括了最初始的大时间尺度扰动产生的位置与条件;大时间尺度扰动失速先兆向脉冲型失速先兆的转化,以及大时间尺度扰动失速先兆尺度随转子转动方向的逐渐减小。说明局部扰动和系统特性之间存在一定的相互关系。

| Abstract: | Experimental research was carried on a three-stage low-speed axial compressor with different inlet distortion. It was discovered that while in many cases the stall precursors were the short length scale spikes, there were some cases where the compressor instability was triggered after the disturbances going through a long-to-short length scale transition. Along axis running direction, the scale of long length scale disturbances decreased. |
