Hydromagnetic flow of a viscous incompressible fluid due to unsteady motion of a flat plate with constant suction

An exact solution of the unsteady motion of an electrically conducting, incompressible and viscous fluid near an infinite porous flat plate moving exponentially with time in its own plane with constant suction, in the presence of uniform transverse magnetic field is obtained. It is assumed that the fluid extends on one side of the wall and is sucked away to the other side. Expressions for the velocity profile and skin friction have been obtained. The results have also been stated graphically. (author)
