A Analysis About MHD, Couple Stress, And The Roughness Of The Surface on A Long Cylinder and Infinite Porous Plate

The paper deals with the analysis about the impact of MHD, couple stress, and roughness of a surface on a cylinder and endless porous flat plate. The expression for film pressure, load, and squeezing time is derived. According to the results, the squeeze film attributes are improved by the effects of surface roughness and lubrication by couple stress fluids in association with the magnetic field. But due to the presence of the permeability parameter a decline in pressure, load, and squeezing time is visible in the bearing attributes.
