Abstract

Combined effects of Dufour, Soret, dissipation, thermal radiation on heat and mass transfer of free convective flow of a viscous incompressible, chemically-reacting and electrically conducting fluid past an impulsively moving vertical plate adjacent to a non-Darcy porous regime in the presence of heat generation, variable surface temperature and concentration conditions have been investigated. The governing non-linear partial differential equations of the flow field were solved using the implicit Crank-Nicolson finite difference method. The velocity, temperature and concentration profiles were studied for different values of thermophysical parameters such as thermal Grashof number, mass Grashof number, Schmidt number, Prandtl number, Dufour number, Soret number, and chemical reacting parameter. Also, numerical values of Skin friction coefficient, local Nusselt number and Sherwood number were computed and analyzed.
