McDougall, NM and Cumpsty, NA and Hynes, TP (1990) Stall inception in axial compressors. Journal of Turbomachinery, 112. pp. 116-125. ISSN 0889-504XFull text not available from this repository.
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. The crucial quantity in both cases is the blockage caused by the endwall boundary layer. Prior to stall, disturbances rotate around the inlet flow in sympathy with rotating variations in the endwall blockage.
