Magneto Hydrodynamic Convective Double Diffusive Fluid Flow Past a Vertical Plate with Varying Temperature and Concentration

Abstract

This manuscript presents the influence of variable boundary of temperature and concentration of a double diffusive unsteady MHD natural convection heat and mass transfer flow past an accelerated vertical porous plate in the presence of thermal radiation and chemical reaction. The dimensionless governing equations along with the relevant boundary conditions are solved numerically by using finite difference method. The effects of pertinent physical parameters on velocity, temperature and concentration are discussed with the help of graphical representations. With the aid of the expression of velocity, concentration and temperature distributions, variations in skin friction, the rate of heat transfer in the form of Nusselt number and the rate of mass transfer in the form of Sherwood number are also analyzed. The velocity decreases with an increase in magnetic parameters and porosity parameter. The temperature increases with an increase in the Dufour number. Concentration falls down under the influence of Schmidt number and chemical reaction.
