Aeroacoustic Simulation for NASA CC3 Centrifugal Compressor Operating at off Design Condition

Alqaradawi, Mohamed; Shahin, Ibrahim; Gadala, Mohamed; Badr, Osama (2016 , Conference)
This paper covers the characterization of the acoustic noise and the unsteady flow field of a high speed centrifugal compressor NASA CC3. In order to accurately predict the noise, all analyses are carried out through the ...
Numerical investigation of rotating stall in centrifugal compressor with vaned and vaneless diffuser

Halawa, Taher; Alqaradawi, Mohamed; Gadala, Mohamed S.; Shahin, Ibrahim; Badr, Osama ( Science Press , 2015 , Article)
This study presents a numerical simulation of the stall and surge in a centrifugal compressor and presents a descriptionof the stall development in two different cases. The first case is for a compressor with vaneless ...
Unsteady CFD simulation for high speed centrifugal compressor operating near surge

Shahin, Ibrahim; Gadala, Mohamed; Alqaradawi, Mohamed; Badr, Osama ( American Society of Mechanical Engineers (ASME) , 2014 , Conference)
Centrifugal compressor surge and stall are an instabilities flow and system phenomenon, which can lead to a loss of engine power, large pressure transients and, in some cases, failure of the compressor and bearing system. ...
