The present paper provides a summary of investigations of the tip air injection, which has
been studied for over 30 years to extend the stall margin in axial flow compressors. The …

Mass injection upstream of the tip of a high-speed axial compressor rotor is a stability
enhancement approach known to be effective in suppressing stall in tip-critical rotors. This …

These lecture notes were presented at the von Karman Institutes lecture series on Advances
in Axial Compressor Aerodynamics, May 2006. They provide a fairly extensive overview of …

Experiments that demonstrate the use of endwall recirculation to control the stall of transonic
compressor stages are described. Endwall recirculation of a compressor stage is …

This paper presents the first attempt to stabilize rotating stall in a single-stage transonic axial
flow compressor with inlet distortion using active feedback control. The experiments were …

Safely operating compressors is quite critical. Rotating stall is highly undesirable and affects
negatively the performance and stability of aero-engine compressors. It is important to …

This paper presents the stall margin enhancement of a novel casing treatment subjected to
circumferential pressure inlet distortion. Experimental results are carried out on a low-speed …

The tip clearance size has historically been considered to be the main factor affecting
stability range in axial fan and compressors. This paper reveals that the stall characteristics …

The reliability of widely studied four stall warning methods, namely, auto-and cross-
correlation, Root-Mean-Square (RMS), and fast wavelet analysis, were experimentally …

A stall inception prediction model considering radial inlet distortions is established in this
paper in order to quickly and accurately predict the stall limit of a compressor at radially …
