UNSTEADY MAGNETO HYDRODYNAMIC POISEUILLE OSCILLATORY FLOW BETWEEN TWO INFINITE PARALLEL POROUS PLATES

Abstract

Alfred studied on the steady Magneto hydrodynamic (MHD) Poiseuille flow between two infinite parallel porous plates in an inclined magnetic field. The case of steady Poiseuille flow without oscillatory to extend the existing work. The study examines the unsteady MHD Poiseuille oscillatory flow between the two infinite parallel porous plates in a magnetic field. The motion of two dimensional unsteady oscillatory flow of viscous, electrically, conducting, incompressible fluid flowing between two infinite parallel plates at constant pressure gradient was examined. The analytical expression for the fluid velocity obtained was expressed in terms of Hartmann number. The effects of the magnetic inclinations, Hartmann number, suction/injection and pressure gradient to the velocity are presented graphically. It was discovered that the increase in the Hartmann number and suction/injection leads to the increase in the velocity.
