Abstract
A numerical study is presented on the effects of chemical reaction and
magnetic field on the unsteady free convection flow, heat and mass transfer
characteristics in a viscous, incompressible and electrically conducting
fluid past an exponentially accelerated vertical plate by taking into account
the heat due to viscous dissipation. The problem is governed by coupled
non-linear partial differential equations. The dimensionless equations of the
problem have been solved numerically by the implicit finite difference method
of Crank - Nicolson?s type. The effects of governing parameters on the flow
variables are discussed quantitatively with the aid of graphs for the flow
field, temperature field, concentration field, skin-friction, Nusselt number
and Sherwood number. It is found that under the influence of chemical
reaction, the flow velocity as well as concentration distributions reduce,
while the viscous dissipation parameter leads to increase the temperature.
