A kinetic model of fluid-wall interaction is proposed, on the basis of a simple extension of Enskog theory of dense fluids. The model leads to a linear integro-differential equation which can be solved by the same statistical particle methods used to solve kinetic equations for dilute or dense fluids. The proposed model is applied to study the heat transport through a low density gas confined between two parallel walls kept at different temperatures. The results are compared with molecular dynamics simulations.
