A journal bearing is a machine part that is used to ensure that the shaft always rotates in the opposite direction of the axis. Journal bearings are chosen because they are well-suited for use in mechanical systems that demand precision, speed, and a high load capacity. Recent years have seen an increase in research on how to improve the tribological performance of bearings by considering the design/architecture of these bearings. Numerous scientists have developed numerous methods for measuring pressure distribution, load-carrying capacity, acoustic power level, force friction, and cavitation phenomena in order to improve the performance of tribology, particularly in journal bearings. As a result, hydrodynamic lubrication was used in the investigation. The investigation was conducted using a computational fluid dynamics (CFD) three-dimensional journal bearing model that took cavitation into account. Additionally,the location of the heterogeneous rough/smooth bearing pattern was modified, as was the shaft rotational speed. The results of this study indicate that when the surface roughness is applied to journal bearings in a variety of locations with heterogeneous rough/smooth bearing patterns, the tribological performance of journal bearings is significantly improved, and that high shaft rotational speed has a significant effect on the tribological performance of journal bearings.
Key words: CFD / hydrodynamic lubrication / surface roughness / heterogeneous rough
