A Study on the Performance of Hydromagnetic Squeeze Film between Anisotropic Porous Rectangular Plates with Couplestress Fluids

Abstract

In the present investigation, a semi analytic and semi Numerical solution of the hydromagnetic squeeze film between anisotropic porous rectangular plates with lubricant additives has been studied. The effect of transverse magnetic field with the lubricants containing additives has been modelled as Stokes couple stress fluid. The more realistic Beavers-Joseph slip boundary conditions are used to derive the most general form of MHD-Reynolds equation, which accounts for the effects due to the lubricant additives and anisotropic nature of the porous material in the presence of transverse magnetic field. The current work aims to achieve better tribological designing for the design engineers to bring in enhanced load carrying capacity and reduced squeeze film time by the application of transverse magnetic field as compared to non-magnetic case and Newtonian case.
