Large eddy simulation for a deep surge cycle in a high-speed centrifugal compressor with vaned diffuser
(The American Society of Mechanical Engineers - ASME, 2015-06)
This paper presents a computational study for a high-speed centrifugal compressor stage with a design pressure ratio equal to 4, the stage consisting of a splittered unshrouded impeller and a wedged vaned diffuser. The aim ...
Coupled finite element modeling of piezothermoelastic materials
(International Society for Optics and Photonics,, 2007)
The governing equations of piezo-thermoelastic materials show full coupling between mechanical, electric, and temperature fields. It is often assumed in the literature that in high-frequency oscillations, the coupling ...
Numerical Simulation of Using Combined Active and Passive Stall Control Techniques in Centrifugal Compressors
This study presents a numerical simulation of stall control by using the casing treatment method which represents the passive control technique and also by using the air injection method which represents the active control ...
Numerical Simulation and Control of Rotating Stall in a Transonic Centrifugal Compressor
(American Society of Mechanical Engineers., 2014-10)
This study presents a numerical simulation of precursors and characteristics of rotating stall in a centrifugal compressor with vaned diffuser. The aim is to further understand the causes of stall inception, characteristics ...
Numerical Investigation of Rotating Stall Characteristics and Active Stall Control in Centrifugal Compressors
(American Society of Mechanical Engineers., 2014-11)
This paper focuses on providing better view for the understanding of rotating stall phenomenon in centrifugal compressors by using numerical simulations and presents a study of the role of air injection method in delaying ...
