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 ...
Influence of changing casing groove parameters on the performance of centrifugal compressors near stall condition
(
American Society of Mechanical Engineers (ASME)
, 2016 , Article)
The casing treatment is an effective method for increasing the stall margin of compressors and enhancing the flow distribution at the blades tip. The present numerical study focuses on making an optimization of the casing ...
