Implicit Scheme Solution of Unsteady MHD Flow

We study the unsteady, electrically transmitting fluid past an oscillating semi-infinite vertical plate with uniform temperature and mass diffusion under Chemical reaction(unimolecular). Complete computations are presented and the impact of chemical reaction for the change in the velocity, heat transfer, fluid concentration, skin -friction, the rate of heat and mass diffusion at the plate are exhibited through graphs. The inference from the current observations is that the chemical reaction has a significant effect in controlling the flow. The heat transfer due to viscous dissipation and the induced magnetic field is considered to be negligible. The consequences of cooling of the plate by free convection currents are studied. The heat transfer progress is found to be enhanced with the oscillation frequency, Prandtl number and thermal Grashof numbers
