Abstract

The slip boundary has a significant impact on the effectiveness of hydrodynamic journal bearing. The slip boundary can be induced by the hydrophobic coating. The favorable influence of slip on thermal behavior, on the other hand, has received less attention. Parameters related to thermo hydrodynamic properties of heterogeneous type of bearing that operates in incompressible, stable, and turbulent states are investigated in this specific scope of research usin g CFD methods. The thermal hydrodynamic behavior of heterogeneous slip/no slip bearings is investigated in terms of volume fraction (VF), temperature, lubricating pressure, and load-carrying capacities when operating at various shaft rotational speeds. The journal bearing's actual operational condition is depicted using the multiphase cavitation model. It is discovered that shaft speed has a significant impact on the boundary condition of a het erogeneous journal bearing in terms of tribological performance. Besides, the maximum hydrodynamic lubricating pressure produced proportionally climbs as the shaft speed on the journal bearing increases. The findings show that as the shaft speed increases, so does the temperature of the lubricant. Moreover, it is found that the effect of slip is desirable in all simulated condition s sin ce it enhances the bearing load support, just as shaft speed does.
