TL;DR: Christensen's stochastic theory of hydrodynamic lubrication of rough surfaces is used to study the effect of surface roughness in an infinitely long porous journal bearing operating under steady conditions as mentioned in this paper.

TL;DR: In this article, a numerical study of the effect of surface roughness on finite porous journal bearing with heterogeneous slip/no-slip surface is presented, where generalized Reynolds type equations are derived for both types of uni-dimensional roughness structure.

TL;DR: In this paper, the effect of surface roughness in hydrodynamic narrow porous journal hearings operating under steady conditions was examined. And the results showed that the results were significantly different than those for the case of an infinitely long journal bearing.

TL;DR: In this article, the effects of surface roughness on a narrow porous journal bearing were studied using Christensen's stochastic theory, and an exact solution for the film pressure and pressure in the bearing material was given for arbitrary wall thickness.

TL;DR: In this article, the effect of velocity slip in rough porous journal bearings operating in the hydrodynamic regime was considered and different forms of Reynolds-type equations were derived for various types of surface roughness pattern.
