This article presents an improvement to a previous multiscale approach used to model the mixed lubrication regime in a mechanical face seal. The physical mechanisms considered by the improved model are the surface roughness effects on the fluid film

Mechanical seals must operate with a fluid film between their faces to avoid wear. This film must be thin enough to prevent excessive leakage. Consequently, mechanical seals work near the transition from mixed to hydrodynamic lubrication regimes wher

This paper presents a multiscale approach to solve the problem of mixed lubrication in mechanical seals. In fact, the lubricating fluid film developed between the faces of mechanical seals is usually a fraction of a micron in thickness, leading to a
