RÉSUMÉ

This paper focuses on the study of the effects of radiation and chemical reaction on unsteady magnetohydrodynamic free convection flow of a dissipative fluid past an impulsively started infinite vertical plate in the presence of Newtonian heating and uniform mass diffusion. The dimensionless governing equations are unsteady, coupled, and nonlinear partial differential equations. An analytical method fails to give a closed-form solution. Hence, the implicit finite difference scheme of the Crank-Nicolson method is employed. The influence of the magnetic field parameter, radiation parameter, and chemical reaction parameter on the velocity field and skin friction for both air (Pr = 0.71) and water (Pr = 7) are extensively discussed with the help of graphs.
