Axial transonic compressor performance enhancement with circumferential grooves [PDF]
Casing treatment has been broadly used as a prudent passive flow control technique to improve the stall margin with a small drop in efficiency. The effect of grooves in certain details is overlooked however, different grooves shape (angels and location ...

A suitable case for treatment [PDF]
In August 1982, I finished a six-month stint as a senior house officer in obstetrics, and brought my career as a hospital doctor to an end. Since then, I have worked mainly in general practice and as an educator. I have only had the typical contacts that you would expect a GP to have with the world of hospital medicine.

Stall Margin Improvement in a Centrifugal Compressor through Inducer Casing Treatment
The increasing trend of high stage pressure ratio with increased aerodynamic loading has led to reduction in stable operating range of centrifugal compressors with stall and surge initiating at relatively higher mass flow rates.

Method of Improving Stability of a Highly-Loaded Axial Compressor Stage by Coupling Different Casing Treatments [PDF]
Casing treatment is a powerful method for improving the stability of aircraft compressors. An optimized slot-type casing treatment was tested on the first rotor of a highly-loaded two-stage compressor, and the results showed that the casing treatment ...
