International Journal of Turbomachinery, Propulsion and Power, 2023 The tip gap region of an axial compressor rotor is a source of complex flows, inducing losses and stability issues. Recent works have proven the ability of blowing high-speed jets in the tip region to improve the surge margin of an axial compressor stage

Modelling Non-Uniform Bleed in Axial Compressors [PDF]
Volume 2B: Turbomachinery, 2015 The coupling between the bleed system and the flowfield of a downstream compressor stage is studied using two approaches. In the first, three-dimensional, full annulus, unsteady computations simulate the flow in a low speed research compressor with non-uniform bleed extraction.
