Numerical analysis of aerodynamic lubricated double-decked protuberant foil thrust bearing
Double-decked protuberant foil bearing is a type of foil bearing that uses two stacking-up layers of protuberant foils as supporting structure. In preliminary experiments, wear failure of foil thrust bearing occurs occasionally due to excessive axial ...

Development of a fluid-structure model for gas-lubricated bump-type foil thrust bearings
In the present study, a computational model for the coupled fluid-structure simulation of bump-type foil thrust bearings is developed. A three-dimensional compressible Navier-Stokes solver is extended to model the fluid flow within the thin gap.
