Surface Roughness Induced Effects in Hydrodynamic Lubrication
Kristian To̸nder
- 01 Jan 1998
TL;DR: In this paper, the effects of surface roughness in hydrodynamic lubrication are discussed, and it is shown that roughness effects are mainly expressed as modifications of Reynolds' equation, which applies to compressible and incompressible fluids alike.

- 01 Jan 2020
TL;DR: In this article, the authors introduce the concept of homogenisation of surface roughness and the relation between homogenised coefficients and the Patir and Cheng flow factors is described and finally it is shown how to incorporate the effect of mixed lubrication into the model.
