MHD Mixed Convective Flow of a Second Grade Fluid in the Presence of Nonlinearized Thermal Radiation, Thermal diffusion and Diffusion thermo Effects

The implicit finite difference method of Crank-Nicolson type is employed to examine heat and mass transfer in a transient magnetohydrodynamic mixed convective flow of a viscoelastic second grade fluid past a vertical porous plate in the presence of nonlinearized thermal radiation, thermal diffusion and diffusion thermo effects. The governing coupled nonlinear time-based partial differential equations are non-dimensionalized by using appropriate dimensionless variables to obtain the dimensionless highly nonlinear partial differential forms of momentum, energy and species concentration equations. These equations are solved numerically in the presence of buoyancy force. The influences of different emerging parameters such as the suction parame ter, second grade parameter, Prandtl number, Lewis number, thermal radiation parameter, temperature difference parameter, Dufour number, Soret number, mixed convection parameter and concentration buoyancy parameter on velocity, temperature and species concentration profiles are plotted and discussed.
