Gas foil bearings, which are oil-free and exhibit low energy losses, are used in high-speed rotating machinery. Because gas is used as the working fluid, there is a need to improve damping performance using support structures. Additionally, the suppo

Rotating machineries supported in journal bearings are operated at a rotational speed between the one where the minimum oil film thickness is ensured to prevent direct contact of the journal and bearing surfaces and the one where self-excited vibrati

Hydrodynamic lubrication is definitely one of the foremost factors upon which the load carrying capacity within journal bearing mainly rely. Therefore, maintaining journal bearing lubrication away from boundary and transient lubrication regions is so
