Get Price2013-1-1 · The results showed that for the cases of thin film lubricated journal bearing, the turbulent models did not give any significant to the simulation results. However for the case of complex geometry, another simulation needs to be conduct to determine an effect of the different turbulent models in the simulation of the lubricant in bearing system.
Get Price2015-2-14 · A thin film lubricated journal bearing is to develop positive pressure by virtue of relative motion of two surfaces separated by a fluid film. Thin film bearings are those in which although lubricant is present, the working surfaces partially contact each other at least part of the time. These bearings are also called Boundary Lubricated Bearings.

Get Price2005-2-1 · Measurements of fluid film pressures were made on water-lubricated rubber journal bearings. The measurements indicated that the film pressure profiles are very different from those of conventional rigid bearings. The relatively low film pressures caused significant rubber deflections but were too low to produce lubricant viscosity changes.
