Abstract
The following deals with effects of surface roughness in hydrodynamic lubrication. Although most of the effects described apply to several types of tribological devices, the discussion is essentially related to bearings. The main reason for this is simply the suitability of bearings for illustration purposes. It is shown that roughness effects are mainly expressed as modifications of Reynolds’ equation. This applies to compressible as well as incompressible fluids alike. The methods used and the difficulties encountered in the derivation of these modifications are described, as are special effects resulting from certain surface roughness structures.
