Nanoscale phenomena in lubrication: from atomistic simulations to their integration into continuous models

Savio, Daniele

Abstract:
In modern lubricated contacts the thickness of the oil film separating the surfaces can decrease to a few molecular diameters. These confined lubricants were studied using Molecular Dynamics. Wall slip was quantified as a function of the materials and local conditions in a contact interface, and then integrated into a macroscopic lubrication model where it caused a severe modification of the film thickness and friction. Local film breakdown was also explored through atomistic simulations.
