Vijaya Kumar T1 RADIATION AND CHEMICAL REACTION EFFECTS ON UNSTEADY MHD FREE CONVECTION FLOW OF A DISSIPATIVE FLUID PAST AN INFINITE VERTICAL PLATE WITH NEWTONIAN HEATING JF Computational Thermal Sciences: An International Journal JO CTS YR 2013 FD 2013-07-03 VO 5 IS 5 SP 355 OP 367 K1 free convection K1 magnetohydrodynamic flow K1 thermal radiation K1 viscous dissipation K1 chemical reaction K1 Newtonian heating K1 Crank-Nicolson method AB 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.
