A new Approach for Estimating the Friction in Thin Film Lubrication

An important problem in the theory of lubrication is to model and analyze the effect of surface roughness on, for example, the friction and load carrying capacity. A direct numerical computation is often impossible since an extremely fine mesh is required to resolve the surface roughness. This suggests that one applies some averaging technique. The branch in matematics which deals with this type of questions is known as homogenization. In this paper we present a completely new method for computing the friction.
