HALL-CURRENT EFFECTS ON UNSTEADY MHD FLOW BETWEEN STRETCHING SHEET AND AN OSCILLATING POROUS UPPER PARALLEL PLATE WITH CONSTANT SUCTION

ABSTRACT
The unsteady MHD flow of an incompressible viscous electrically conducting fluid between two horizontal parallel non conducting plates, where the lower one is stretching sheet and the upper one is oscillating porous plate, is studied in the presence of a transverse magnetic field and the effects of Hall current. Fluid motion is caused by the stretching of the lower sheet and a constant suction is applied at the upper plate which is oscillating in its own plane. The stretching velocity of the sheet is assumed to be a linear function of distance along the channel. The expressions relating to the velocity distribution are obtained and effects of different values of various physical parameters are calculated numerically and shown graphically.
