Surface roughness effect on couple stress fluid lubricated Porous pivoted slider bearings

AbstractA theoretical model is developed to study the surface roughness effect on couple stress fluid lubricated Porous pivoted slider bearings. Mathematical model of Reynolds equation is obtained for rough porous pivoted slider bearing. Capacity for load bearing and point where pressure is centered are evaluated in form of various parameters that are couple stress, permeability and surface roughness. It is concluded that capacity for load bearing increases with roughness and decreases with increases in permeability parameters. Normal behaviour exists for surface roughness parameters with pressure and pressure with permeability parameters.
