Hydromagnetic Squeeze Films between Porous Rectangular Plates with Couplestress Fluids

The theoretical investigation made in this paper is to study the effect of transverse magnetic field on the performance characteristics of porous squeeze film lubrication between two rectangular plates with couplestress fluids. A most general modified Reynolds equation is derived using Stokes consti...
