The couple stresses effects are analyzed based on Stokes micro-continuum theory. The nondimensional pressure and shear stress expressions are derived using modified Reynolds equation. The nondimensional load capacity increases and the coefficient of friction decreases using nanoparticle additive lubricants with couple stress effects. The three-layered journal bearing performance characteristics are improved with increase in both (i) surface adsorbent fluid film layer thickness and (ii) dynamic viscosity ratio of surface to core layer. %Z cited By 8; Conference of 3rd ISESCO International Workshop and Conference on Nanotechnology 2012, IWCN 2012 ; Conference Date: 5 December 2012 Through 7 December 2012; Conference Code:96795
