Single and Multiple Circumferential Casing Groove for Stall Margin Improvement in a Transonic Axial Compressor [PDF]
Volume 2A: Turbomachinery, 2020 Abstract The stability limit of a tip-stalling axial compressor is sensitive to the magnitude of the near casing blockage. In transonic compressors, the presence of the passage shock could be a major cause for the blockage. Identification and elimination of this blockage could be key to improving the stability limit of the compressor. In

Pulsed Air Injection System Characterization for Stall Margin Improvement in an Axial Compressor
, 2022 This paper presents the design and the characterization of a pulsed air injection system on a single stage axial compressor. The goal of this system is to delay the rotating stall onset and to extend the compressor operating range. The proposed control system consists in 20 injection blocks of 2 injectors, allowing to adjust some of the fluidic and ...
