A numerical method for the calculation of lubricant pressures in bearings with mixed lubrication
Tribology International, 1982Abstract A model for mixed lubrication, assuming that the total normal load applied to the plane of the lubricated surfaces is carried partly by the hydrodynamic action of the lubrication film and partly by asperity contacts and that the total friction force between the lubricated surfaces is partly due to viscous friction and partly to asperity ...

Mixed Mechanism of Lubrication by Lipid Bilayer Stacks
Langmuir, 2015Although the key role of lipid bilayer stacks in biological lubrication is generally accepted, the mechanisms underlying their extreme efficiency remain elusive. In this article, we report molecular dynamics simulations of lipid bilayer stacks undergoing load and shear.

Three-dimensional mixed lubrication analysis of spur gears with machined roughness
, 2019The timing gears of the ship internal combustion engine usually undergo dynamic loading conditions, and often work in a mixed lubrication state. In this study, by considering the three-dimensional (3D) machined roughness, an integrated model with the ...

La lubrification mixte intervient dans un contact travaillant en présence d’un lubrifiant liquide, mais dans les conditions particulières de fonctionnement qui conduisent à l’absence d’une séparation complète des 2 pièces en regard, par le film lubrifiant.

Simulation of Sliding Wear in Mixed Lubrication
Journal of Tribology, 2007Sliding wear is a significant surface failure mode in many mechanical components. The magnitude of changes in surface topography due to wear may be comparable to or larger than the original surface roughness and elastic deformation. However, wear has rarely been incorporated into the numerical models used as predictive tools in engineering practice ...

Micro-pitting presents a failure of the rolling/sliding contact metal asperities operating under boundary/mixed lubrication conditions. The studies have shown that micro-pitting failure competes with mild wear and that lubricant additives can have either

A Mixed Flow Model for Lubrication with Emulsions
Tribology Transactions, 1994An oil-in-water emulsion in the inlet zone of a concentrated contact is modeled by treating the oil particles as flattened cylinders surrounded by water. In an independent flow model, the oil and water flows are coupled only through the pressure gradient. However, the model leads to anomalous behavior with regard to the flow of water.
