Experimental and CFD analysis of a gas-lubricated foil thrust bearing for various foil configurations [PDF]

FME Transactions, 2023
Thrust foil bearings operating at hydrodynamic conditions are self-acting (aerodynamic) bearings that support high-speed shafts at mild loading conditions with air as a lubricant and are generally used in low-power gas turbines.

Improvement of Thrust Bearing Calculation Considering the Convectional Heating within the Space between the Pads

Lubricants, 2018
A modern thrust bearing tool is used to estimate the behavior of tilting pad thrust bearings not only in the oil film between pad and rotating collar, but also in the space between the pads. The oil flow in the space significantly influences the oil film
