Centrifugal Compressor Spiral Dry Gas Seal Simulation Working at Reverse Rotation

Ibrahim, Shahin; Gadala, Mohamed; Alqaradawi, Mohamed; Badr, Osama ( Elsevier Ltd , 2013 , Conference)
Unidirectional dry gas seal may experiences reverse rotation when equipped in a centrifugal compressor. This paper describes how the reverse rotation effects on the spiral unidirectional dry gas seal performance and pressure ...
On the aero acoustic and internal flows structure in a centrifugal compressor with hub side cavity operating at off design condition

Ibrahim, Shahin; Alqaradawi, Mohamed; Gadala, Mohamed; Badr, Osama ( 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 ...
Three Dimensional Computational Study for Spiral Dry Gas Seal with Constant Groove Depth and Different Tapered Grooves

Ibrahim, Shahin; Gadala, Mohamed; Alqaradawi, Mohamed; Badr, Osama ( Elsevier Ltd , 2013 , Conference)
The three dimensional simulation for dry gas seal with constant depth spiral grooves and with different taper grooves is done using ANSYS FLUENT CFD code. Grid independence study and code validation are done with experimental ...
