• COMBINED EFFECTS OF COUPLE STRESS AND MHD ON SQUEEZE FILM LUBRICATION BETWEEN TWO PARALLEL PLATES
Abstract
This paper presents theoretically the combined effects of couple stress and magnetic field between two parallel plates of which upper plate has roughness surface and lower has smooth material. The lubricating fluid is linearly viscous, isothermal, incompressible, electrically conducting fluid in the presence of uniform transverse magnetic field. This model incorporates the appropriate no-slip boundary conditions. The finite difference based multigrid method is applied to solve the modified Reynolds equation. The bearing characteristics such as pressure distribution and load carrying capacity are obtained for different values of couple stress parameter and Hartmann number. The results reveal that the bearing characteristics such as pressure distribution and load carrying capacity increases for increasing couple stress parameter and Hartmann number compared to classical Newtonian case.
