Solid-Liquid Interface Slip as a Rate Process Available to Purchase

Thin film lubrication may be significantly affected by slip at the solid-liquid interface. Slip occurs when there is a jump in the mean speed between the walls and the first layer of liquid molecules. Using molecular simulation, we show that the amount of slip is greatly affected by solvation pressure and that this dependence can be accounted for by treating slip as a rate process. This treatment enables formulation of a quantitative relationship between solvation pressure and interface slip.
