Due to the relatively low load-carrying capacity, low-viscosity lubricated bearings can easily operate in a mixed-lubrication regime. Furthermore, low lubricant viscosity may cause local turbulence in the area with relatively thick film.

This paper presents a model for mixed lubrication. The surface asperities are represented by short plasto-elastic cylinders with spherical tops. The heights of these cylinders are assumed to have a Gaussian distribution. By combining the solution of the Reynolds equation and the solution from boundary lubrication theory or the microelastohydrodynamic ...
