Numerical Investigation of the Circumferential Grooved Casing Treatment as well as Analyzing the Mechanism of Improve Stall Margin

2007
The Circumferential Grooved Casing Treatment is known as a powerful method to enhance the flow stability in compressors. Numerical investigation was conducted to study the influence on a subsonic compressor performance with the circumferential grooved configuration.

The Mechanism of Stall Margin Improvement in a Centrifugal Compressor with the Air Bleeding Circumferential Grooves Casing Treatment

2007
The air bleeding circumferential grooves casing treatment has the potential to extent the operating range of centrifugal compressor with no loss in efficiency. A time accurate 3-dimentional numerical simulation was performed in a low speed centrifugal compressor with the air bleeding circumferential grooves casing treatment.

Optimized Casing Treatment to Improve Stall Margin Under Circumferential Pressure Distortion in a High-Speed Axial Flow Fan

Journal of Turbomachinery
Abstract An optimized axial slot casing treatment (OPCT) was designed that experimentally improves the stall margin by 7.31% with an efficiency gain of 1.94% at a design speed of 100% in a high-speed axial flow fan. Subsequently, the OPCT was tested under the distorted inflow with a 9% composite distortion index; it can still improve the

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.
