Overview

This study shows the effects of inlet distortion on stall behavior in high-load compressors, suggesting tip air injection enhances stability.

Key Points

  • Stall inception in high-load compressors remains modal under uniform distortion, but tip radial distortion triggers spike-type stall.
  • Tip air injection enhances stall margin by up to 5% and suppresses tip leakage flow fluctuations during spike-type onset.
  • As injection mass flow increases, spike-type inception can revert to modal wave behavior, clarifying stability mechanisms.
  • The findings provide practical insights into utilizing tip air injection under various inlet distortion conditions.
