Stall Inception in Axial Compressors

Volume 1: Turbomachinery, 1989
Detailed measurements have been made of the transient stalling process in an axial compressor stage. The stage is of high hub-casing ratio and stall is initiated in the rotor. If the rotor tip clearance is small stall inception occurs at the hub, but at clearances typical for a multistage compressor the inception is at the tip.

Simulating Stall Inception in a High-Performance Fan

Volume 13A: Turbomachinery — Axial Flow Fan and Compressor Aerodynamics, 2023
Abstract Aircraft engine performance and stability is limited by the onset of flow instabilities, such as rotating stall or surge. Although much research has been conducted on the subject, the mechanisms by which spike-type stall inception occurs in highspeed machines are still not well understood.

Spatial Correlation Based Stall Inception Analysis

Volume 6: Turbo Expo 2007, Parts A and B, 2007
Investigations of stall inception and compressor pre-stall behavior have used a variety of techniques to make inferences about the mechanisms of rotating stall inception. Many of these techniques utilized data from arrays of circumferentially spaced hot-wires or high frequency response pressure transducers.
