Soret and Dufour effects on two dimensional steady MHD flow past a semi-infinite vertical porous plate in the presence of thermal radiation and radiation heat absorption with constant heat and mass flux

The problem of a two-dimensional steady, MHD convective, incompressible, viscous flow past a uniformly moving semi-infinite vertical porous plate embedded in a porous medium in the presence of radiation heat absorption, thermal radiation, thermal diffusion, and diffusion thermo effects with constant heat and mass flux are studied. In the fluid region, a transversely oriented, homogeneous magnetic field of intensity B0$B_0$ is applied. The non-dimensional governing equations are solved analytically adopting asymptotic series expansion method. The impacts of several physical quantities including Grashof number, Schmidt number, Prandtl number, Soret number, radiation absorption, radiation parameter, magnetic field within the flow domain and transport characteristic have been explored graphically. It has been found that fluid velocity and skin friction fall with enhancing the values of magnetic parameter. Further, temperature and concentration fields rise with an increase in the Soret effect.
