Large eddy simulation of surge inception and active surge control in a high speed centrifugal compressor with a vaned
(Shahin, I., Alqaradawi, M., Gadala, M., & Badr, O. (2016). Large eddy simulation of surge inception and active surge control in a high speed centrifugal compressor with a vaned diffuser. Applied Mathematical Modelling, 40(23-24), 10404-10418., 2016)
In this study, we present a numerical investigation of active surge control and perfor- mance improvement for an aero engine centrifugal compressor (NASA CC3) using self- recirculating bleed slots with different bleeding ...
On the aero acoustic and internal flows structure in a centrifugal compressor with hub side cavity operating at off design condition
(Elsevier, 2017-01)
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 ...
Centrifugal Compressor Spiral Dry Gas Seal Simulation Working at Reverse Rotation
(Elsevier, 2013)
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 ...

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
(Digital Collection: American Society of Mechanical Engineers, 2014-09)
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. ...
Centrifugal compressor spiral dry gas seal simulation working at reverse rotation
(Science Direct, 2013-01)
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 ...
Three dimensional computational study for spiral dry gas seal with constant groove depth and different tapered grooves
(Science Direct, 2014-04)
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 ...
