Abstract
Cavitation is an important phenomenon in hydrodynamic lubrication that considerably affects the performance of journal bearings. In this context, the present work aims to investigate the cavitation effect on the performance of a plain journal bearing using OpenFOAM®, an open-source software for Computational Fluid Dynamics (CFD) based on the Finite Volume Method (MVF). The obtained results demonstrated that due to the cavitation effect, the pressures in the divergent zone of the bearing cannot be lower than the oil vapor pressure, resulting in an asymmetric pressure distribution and, consequently, a reduction of the load-carrying capacity of the bearing.
