An Experimentally Validated Cavitation Model for Hydrodynamic Bearings Using Non-Condensable Gas

Lubricants
Despite great research effort in recent decades, cavitation in hydrodynamic journal bearings is still a not completely understood phenomenon. In particular, it is unclear which proportions of different cavitation types are present in a bearing.

Uncertainty Quantification in Hydrodynamic Bearings

Energy Procedia, 2018
Abstract Although it is possible to imagine a strong sensitivity of hydrodynamic bearings performance to geometrical and fluid dynamic uncertainties, a small amount of scientific contributions have been found in literature about the use of uncertainty quantification techniques for the numerical modeling of bearings.
