Thermal Elastohydrodynamic Lubrication of Non-Newtonian Fluids With Rough Surfaces

Journal of Tribology, 1997
The characteristics of thermal elastohydrodynamic lubrication by non-Newtonian fluids for rough surfaces is investigated theoretically. The general Reynolds equation for two-sided striated roughness lubricated by power law fluids is established using a perturbation approach.

Thermal Non-Newtonian Elastohydrodynamic Lubrication of Rolling Line Contacts

Journal of Tribology, 1991
The two-dimensional thermal elastohydrodynamic equations were numerically solved for a Ree-Eyring type lubricant under pure rolling conditions. Profiles of lubricant pressure, film thickness, and temperature were obtained for medium to heavy loads and moderate to high rolling speeds.

Numerical modelling of thermal effects in elastohydrodynamic lubrication solvers

2003
The numerical modelling of thermal effects in elastohydrodynamic lubrication solvers is addressed by extending the code of the authors. This code is used to investigate the important effect of shear upon the temperature profiles for both a steady state and a transient line reversal example and also for a steady state point contact problem.

On the compressive heating/cooling mechanism in thermal elastohydrodynamic lubricated contacts

Tribology International, 2015
Abstract The importance of compressive heating/cooling occurring within lubricating films in thermal elastohydrodynamic lubricated contacts has not been given sufficient attention in the literature. This paper presents a numerical investigation of this mechanism and attempts to quantify its importance as compared to shear heating under pure-rolling ...

A Parametric Analysis of the Thermal Shear Localization in Elastohydrodynamic Lubrication Films

Journal of Tribology, 2005
Experiments and computer simulations have revealed some unusual results of elastohydrodynamic lubrication (EHL) associated with a high degree of thermally induced inhomogeneous shear across the lubricant film, or thermal shear localization. The results include the development of a sizable film dimple in the central EHL region and a dramatic reduction ...

Line contact thermal elastohydrodynamic lubrication subjected to longitudinal vibration

2003
Complete numerical analysis was carried out for the time-dependent, thermal elastohydrodynamic lubrication (EHL) of line contacts. It was assumed that the contact was composed of an infinite plane and an infinitely long roller. The surfaces were running in opposite directions so that a deep dimple was produced by the action of the thermal viscosity ...

Influence of the Experimental Apparatus on Thermal Effects in Elastohydrodynamic Lubricated Contacts

2009
Thermal effects influence film thickness and friction, particularly in lubricated non-conformal contacts at high values of rolling and sliding velocities. Some effects depend on the lubricated contact itself, but some others are related to the surrounding conditions. In this paper, an experimental work is presented, where three spherical specimens with
