Non-Newtonian inertial magnetohydrodynamic porous squeeze film lubrication between circular discs

This paper presents a numerical investigation of porous squeeze film between two circular discs of couple stress conducting lubricant in the presence of externally applied magnetic fields taking into account fluid inertia forces. The latter are considered using the reduced Navier-Stokes equations. The fluid flow within the porous disc is modeled by the modified Darcy law. The governing equations are resolved by successive over relaxation method in a sequential coupling algorithm. From the results obtained, the influence of transverse magnetic field, inertia forces and couple stress are to improve the porous squeeze film characteristics.
