Free Convective MHD Radiative Flow Past a Porous Vertical Plate in a Porous Medium with Chemical Reaction

Abstract

An analytical solution for two-dimensional steady, viscous, incompressible hydromagnetic free convective flow past a uniformly moving vertical porous plate embedded in a porous medium in the presence of the Soret effect and chemical reaction is investigated in this paper. A uniform magnetic field is applied perpendicular to the plate and directed into the fluid region. The asymptotic series expansion method is used to solve the non-dimensional governing equations. The effects of thermal diffusion, magnetic field, thermal radiation, Grashof number, and chemical reaction are mainly focused on discussing the present problem. One of the significant findings of this study includes that an upsurge in the chemical reaction causes a downfall in the fluid temperature. It is seen that the Soret number enhances the velocity and temperature. Further, the fluid's velocity, concentration, and temperature decrease with an increase in the magnetic field parameter. In most works dealing with convective MHD flow, ohmic dissipation and viscous dissipation are neglected. In this work, these two effects are considered. Further, the Soret effect and the effect of first-order chemical reactions are also considered.
