Aerodynamic Analysis of Helium Lubricated Gas Foil Journal bearing

Objective: Abstract Gas Foil Bearings (GFBs) are used for several high-speed applications such as cryogenic turboexpander, turbochargers, etc. Present research target to design gas foil journal bearing for helium turboexpander used in cryogenic application to liquefy the gasses. The process gas or helium is used as…
