Abstract

The paper describes the results of a numerical study concerning the effect of two-sided roughness in a finite width slider bearing. The analysis is based upon the assumption that Reynolds equation holds in the presence of roughness and uses Christensen's stochastic models as extended to two-sided roughness. Detailed results for various bearing characteristics as a function of width/length and film thickness ratio show that these parameters have a strong influence on the bearing behaviour.
