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 Paper)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. ...
