Influence Of Viscosity Changes On The MHD Squeeze Film Lubrication Using Couple Stress Fluids Between Circular Plates

Abstract

A circular bearing has been analysed to evaluate the effect of couple stress, viscosity pressure dependence (VPD) and magnetic field. Using the Barus formula and Stokes theory, the Reynolds equation has been obtained. The squeeze film pressure, load carrying capacity, and squeeze film time are expressed mathematically. For various parameters, outcomes are graphically shown in two- and three-dimensional formats. Presence of the viscosity variation parameter, MHD, and couple stress parameter clearly amplifies the film pressure, load-carrying capacity, and squeeze film time in comparison to the scenario with non-viscosity variation, non-magnetic, and Newtonian cases.
