CFD Analysis of Hydrodynamic Journal Bearing
Abstract: Journal bearings have the longest history on scientific study of any class of fluid-film bearings. These journal bearings are widely used in most of the rotating machineries due to its high load-carrying capacity and formation of fluid-film thickness during the operation. This research paper represents performance evaluation of hydrodynamic journal bearing using Computational Fluid Dynamics (CFD) approach. For this study, two different geometrical bearings are considered (circular and non-circular) operating …

Identification of Axial Air-Foil Bearings and Radial Air-Foil Bearings
Abstract: Air-foil bearings (AFBs) are self-acting hydrodynamic bearings, a shaft is supported by a compliant, spring-loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air) pushes the foil away from the shaft so that there is no contact. The shaft and foil are divided by air's high pressure which is produced by the rotation which pulls gas into the bearing via viscosity effects. AFBs provide …
