Abstract
Theoretical field of study of combined effects of surface roughness and couple stress on journal bearing considering cavitations condition is analyzed. The modified Reynolds equations accounting for the couple stress and surface roughness, using deterministic theory. It is applied to study the effect of couple stress; Expressions for Load capacity are studied by evaluating them numerically, for various parameters. From the numerical computation of the result ,it is observed that the effect of cavitations point is increase the load carrying capacity decreases. The cavation point is inversely proportional to the load; A parameter characterizing different type of roughness is identified. It is also observed that load capacity diminishes, and cavation point for longitudinal increase for roughness pattern.
