Abstract:In industrial applications, a starved lubrication condition may occur, leading to a reduction in film thickness; by modifying the surface geometry, the tribological performance of the contact is enhanced. In this paper, the influence of surface texturing as a method for reducing the friction on the film thickness in parallel sliding surfaces for starved lubricated contacts is investigated. The results in this study have shown that surface texturing can improve film formation for starved lubricated contacts and, respectively, the load carrying capacity. The effect of starvation on several texturing patterns with several texturing properties was investigated and the film thickness for these conditions was studied. With the numerical algorithm developed and taking cavitation into consideration, the effect of shape, depth, size, and texture pitch on the film thickness was studied.

“…Shyu et al [16] analyzed the velocity and temperature distributions, and pressure distribution using the Legendre collocation method, the bulk-flow model and Elord' s cavitation algorithm. Braun et al [17] learned that the cavitation pressure is not common and changed with the axial and circumferential location by experiment. Croper et al [18] observed that cavitation pressure is not common and the cavitation shape can be acquired by shear mechanism.…”

Abstract-Hybrid sleeve bearings are normally lubricated with high viscosity lubricant, the temperature of oil film increases with the increase of rotating speed. The low viscosity lubricant can decrease the temperature, which is the efficient method to increase the rotating speed of hybrid sleeve bearings. A current situation of the published research works on high speed sleeve bearing with low viscosity lubrication was summarized. The structure of high speed sleeve bearing with low viscosity lubrication was introduced, the effect of wall slip, cavitation, surface roughness, temperature and et al. on bearing properties was analyzed, and the significance of lubrication study for high speed journal bearing with low viscosity lubricant was discussed.

“…Many authors have offered analytical and numerical solutions, the list of excellent contributions being too long to do it justice here. The interested reader is further referred to review publications of Dowson et al [6], Brewe et al [7], and Braun and Hannon [8]. Zuber and Dougherty [9] in 1982 were the first to propose a model for a homogeneous two-phase lubricating film mixture in conjunction with the RE.…”

Abstract. In the 'universe' of the general cavitation phenomena the issue of cavitation in bearings, due to its particular application and the mostly non-homogeneous working fluids associated with it, has presented a rather specialized challenge. The present paper models the phenomenon of pseudo-cavitation in fluid film bearings and offers a physics-based approach that conserves mass while solving the Reynolds (RE) and Rayleigh-Plesset (RP) equations in a coupled, fully transient environment. The RP solution calculates a time dependent void fraction synchronized with the RE transient solution, where density and viscosity are (re)calculated at every grid point of this homogeneous two-phase fluid. The growth and evolution of the cavitation zone expanse is physics-based and thus can accommodate evaporation, diffusion, or pseudocavitation as separate processes. This is a step beyond the present available cavitation models both for the RE and the Navier-Stokes equations.
