Effect of a Recirculating Type Casing Treatment on a Highly Loaded Axial Compressor Rotor
International Journal of Turbomachinery, Propulsion and Power, 2019 The tip leakage flow over the blades of an axial compressor rotor adversely affects the axial rotor efficiency and can determine the onset of tip leakage stall.

Analysis of the Unsteady Flow Field in a Centrifugal Compressor from Peak Efficiency to Near Stall with Full-Annulus Simulations [PDF]
, 2014 This study concerns a 2.5 pressure ratio centrifugal compressor stage consisting of a splittered unshrouded impeller and a vaned diffuser. The aim of this paper is to investigate the modifications of the flow structure when the operating point moves from

Effects of Tip Clearance on Stall Inception in a Multistage Compressor [PDF]
Journal of Propulsion and Power, 2018 Rotor tip clearance height and the associated tip leakage flow have a significant effect on the performance and stability of compressors. Existing studies considering tip clearance effects on stability have been primarily limited to low-speed compressors, and many of these evaluated single-stage machines, which may not adequately represent stall trends
