This paper presents an analysis of journal bearing lubricated with couple stress fluids considering the effects of a layer adhered to bearing surface. The modified classical Reynolds equation is derived considering the effects of surface layer and couple stress fluids. In the present study, the effects of couple stresses on the steady state journal bearing performance characteristics are analyzed based on Stokes micro-continuum theory. The Reynolds boundary conditions are used in the analysis to predict non-dimensional load capacity and coefficient of friction. Results of non-dimensional load capacity and coefficient of friction are presented. Both surface layer and couple stress fluid film improve the characteristics of journal bearing. The influence of surface layer on the journal bearing characteristics are significant for higher dynamic viscosity ratio of surface layer to couple stress fluid film. |
