Stall Margin Improvement in a Centrifugal Compressor through Inducer Casing Treatment [PDF]
International Journal of Rotating Machinery, 2016 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.

Effect of a Recirculating Type Casing Treatment on a Highly Loaded Axial Compressor Rotor
International Journal of Turbomachinery, Propulsion and Power, 2019 The tip leakage flow over the blades of an axial compressor rotor adversely affects the axial rotor efficiency and can determine the onset of tip leakage stall.

Improvement of Moderately Loaded Transonic Axial Compressor Performance Using Low Porosity Bend Skewed Casing Treatment [PDF]
International Journal of Rotating Machinery, 2014 This paper presents experimental results of a single stage transonic axial flow compressor coupled with low porosity bend skewed casing treatment. The casing treatment has a plenum chamber above the bend slots.

A suitable case for treatment [PDF]
QJM, 2007 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.

Influence of Axial Position of Self-Circulating Casing Treatment on the Performances of a Centrifugal Pump at Low Mass Flow Conditions [PDF]
Journal of Applied Fluid Mechanics, 2022 Centrifugal pumps often deviate from its design condi-tion during its operation and work at low mass flow conditions. Under such circumstances, unstable flow phenomena may be generated, affecting the efficient and stable operation of pumps. In this paper,

Fan Stability Enhancement With Partial Casing Treatments
, 2022 Casing treatments are used to extend the stability margin of fans or compressors. These typically have an axisymmetric arrangement, but for a fan exposed to non-axisymmetric distortion, a casing treatment applied to a fraction of the annulus is of ...
