Stall Margin Improvement by Casing Treatment—Its Mechanism and Effectiveness

Journal of Engineering for Power, 1977
Experiments on the effect of casing treatment were carried out using low-speed axial-flow compressors. Results on the overall compressor performance and on the flow through the blade row as well as the flow within the treatment slots are presented. Then, based on the experiments, a possible mechanism of the stall margin improvement is suggested.

Stall Margin Improvement of a Single Stage Transonic Axial Flow Compressor Using Naturally Aspirated Slots

ASME 2015 Gas Turbine India Conference, 2015
This paper describes the method to improve the stall margin of transonic axial flow compressor by controlling the boundary layer on the suction surface of the rotor blade tip through natural aspiration. Aspiration slots in the compressor blade are intended to energize the flow by increasing its momentum on the suction surface.

Computational study of the aerodynamic impact of stall margin improvements in a high tip speed fan

, 2009
Liebherr develops air systems, which can include low transonic, low pressure ratio, and low solidity axial fan. The operating range for such a fan needs to be as wide as possible. Thus, the goal of this study is an improvement of stall margin without performance modification.
