OSCILLATORY MHD FLOW IN A ROTATING HORIZONTAL POROUS CHANNEL FILLED WITH A POROUS MATERIAL IN PRESENCE OF SUCTION/INJECTION

摘要

An analysis is made to study the effects of injection/ suction on an oscillatory flow of an incompressible electrically conducting viscous fluid in a porous channel filled with a porous material. The porous channel with constant injection / suction rotates about an axis perpendicular to the plates. A uniform magnetic field is applied normally to the plates. The upper plate is allowed to oscillate in its own plane whereas the lower plate is kept at rest. Effects of typical results are illustrated to reveal the tendency of the solutions. Representative results are presented for resultant velocities, phase angles and amplitude and phase difference of shear stress.
