Abstract
An analysis is carried out to study the effect of heat and mass transfer on a
non-Newtonian-fluid between two infinite parallel walls, one of them moving
with a uniform velocity under the action of a transverse magnetic field. The
moving wall moves with constant velocity in the direction of fluid flow while
the free stream velocity is assumed to follow the exponentially increasing
small perturbation law. Time-dependent wall suction is assumed to occur at
permeable surface. The governing equations for the flow are transformed into
a system of nonlinear ordinary differential equations by perturbation
technique and are solved numerically by using the shooting technique with
fourth order Runge-Kutta integration scheme. The effect of non-Newtonian
parameter, magnetic pressure parameter, Schmidt number, Grashof number and
modified Grashof number on velocity, temperature, concentration and the
induced magnetic field are discussed. Numerical results are given and
illustrated graphically for the considered Problem.
