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 ...
Optimized statistical parameters of acoustic emission signals for monitoring of rolling element bearings
(
SAGE Publications Ltd
, 2016 , Article)
Acoustic emission (AE) signal generated from artificial defects in rolling element bearings are investigated using experimental measurements in this paper. Rolling element bearings are crucial parts of many machines and ...
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

On the aero acoustic and internal flows structure in a centrifugal compressor with hub side cavity operating at off design condition
(
Elsevier
, 2016 , Article)
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 ...
