Abstract: An analysis of unsteady MHD flow of an electrically conducting visco-elastic fluid confined between
two horizontal parallel non conducting plates in presence of a transverse magnetic field and Hall current is
presented. The lower plate is a stretching sheet while the upper one is an oscillating porous plate, which is
oscillating in its own plane. The motion of the fluid is produced by the stretching of the lower plate. A constant
suction is applied at the upper plate and the stretching velocity is taken to be a linear function of distance along
the channel. The equations governing the flow field are solved by perturbation technique. Expressions for
velocity distribution of the flow field and non-dimensional skin-friction coefficient are obtained and presented
graphically to observe the visco-elastic effect in combination of other flow parameters involved in the solution.
The flow field is observed to be considerably affected by the visco-elastic parameter.
