Dry gas seal simulation with different spiral tapered grooves
(
UiTM Press
, 2014 , Article)
The flow and performance analysis for a dry gas seal (DGS) with a standard and tapered spiral grooves is developed using a verified FLUENT CFD model. A comprehensive analysis is proposed to resolve the effect of modifying ...
Effect of blade tip geometry on centrifugal compressor performance and stability
(
Medwell Journals
, 2016 , Article)
The reliability operation for small fuel cells and hybrid fuel cell with gas turbine requires centrifugal compressor surge prevention. This study concerns a high speed centrifugal compressor stage with different blade tip ...
Large eddy simulation of surge inception and active surge control in a high speed centrifugal compressor with a vaned diffuser
(
Elsevier Inc.
, 2016 , Article)
In this study, we present a numerical investigation of active surge control and performance improvement for an aero engine centrifugal compressor (NASA CC3) using self-recirculating bleed slots with different bleeding ...
Aeroacoustic Simulation for NASA CC3 Centrifugal Compressor Operating at off Design Condition
(2016 , Conference Paper)
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 ...
Unsteady CFD simulation for high speed centrifugal compressor operating near surge
(
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. ...
