Abstract

The effects of adsorbed gas layers on gas-surface interaction is investigated by a kinetic model based on the Enskog-Vlasov equation. The onset of collisional effects in the gas layer is studied by equilibrium simulations. The effects of adsorption on the gas-wall friction forces is investigated in a simple Couette flow geometry. It is shown that gas adsorption might reduce tangential stresses, as indicated by molecular dynamics based studies. Finally an example is produced in which the two-dimensional Enskog-Vlasov equation is solved to simulate the formation of a liquid film on the walls of a planar channel.
