Temperature distribution in the lubricant film of sliding bearings under intensive lubricant-wall heat transfer conditions

It is assumed that the existence of some discontinuities in the experimentally determined circumferential temperature distribution of journal bearings is determined by the lubricant-wall heat transfer and the local hydrodynamic flow conditions. From this hypothesis a simplified theoretical model is proposed which uses adequate boundary conditions and reveals the existence of these discontinuities.The theory is developed by assuming both constant viscosity and a mean viscosity, constant across the film thickness, but varying with its length.
