JOURNAL bearingsRISK aversionFRICTIONVISCOSITYDue to the low viscosity of water, water-lubricated bearings are susceptible to significant wear and noise in demanding operating conditions. It has been demonstrated that a small quantity of secondary lubricating medium can improve the...
This paper presents the development of a numerical model for high speed and water lubricated journal bearings with different boundary slip arrangements. The effect of boundary slip and its possible mechanism are analyzed and discussed. The results suggest that a suitable combination of slip/no-slip ...

Pai et al. [14], [15], [16], [17] derived a model for water-lubricated journal bearings with multiple axial grooves. This model, however, does not consider the elastic deformation of rubber. On the other hand, a thin elastic liner model was used to examine the static and dynamic rubb...
In this theory, the journal bearings were investigated numerically in three dimensions by using FLUENT software [23], and the viscosity changes have a significant impact on the pressure distribution, cavity volume, and load-bearing capacity. Furthermore, based on the multi-phase flow cavitation ...
