“…Reddy et al 6 made a numerical analysis of an unsteady MHD laminar boundary layer flow over an accelerated moving vertical plate by considering the effects of chemical reaction, heat absorption, and radiation. Agarwalla and Ahmed 7 studied MHD mass transfer flow past an inclined plate embedded in a porous medium in presence of thermal radiation and heat source. The effect of thermal radiation on the MHD flow of a viscous incompressible fluid past an impulsively started oscillating plate has been investigated by Appidi et al 8 The effect of energy flux generated due to concentration gradient, on the flow characteristics is called the Dufour effect or diffusion-thermo effect.…”

In this study, we investigate the heat and mass transfer in MHD convective flow past an infinite plate, through a porous media in presence of radiation, diffusion-thermo effect, and heat sink. A uniform magnetic field is applied transversely in the fluid region. The novelty of the present work is to analyze the diffusion-thermo effect on the flow phenomena in the presence of heat sink and thermal radiation. The governing equations are solved by perturbation technique to get expressions for velocity, temperature, and concentration fields. The influence of various physical quantities on the flow domain is studied graphically and in tabular form. It has been found that when heat flux is generated due to temperature gradient, the fluid velocity increases whereas the fluid temperature falls due to the diffusion-thermo effect. The current results have been compared with the existing results in some cases and it has been found that the findings of the present study are consistent with earlier findings.

“…The hydromagnetic free convective flow of electrically and thermally conducting and chemically reacting fluid through a porous regime has become an emerging topic of research in recent years due to its many industrial applications such as aerodynamics, polymer processing, and nuclear engineering. Inspired from these industrial applications, Alagoa and Tay, 1 Singh et al, 2 Barik et al, 3 Manglesh and Gorla, 4 Ibrahim et al, 5 Iqbal et al, 6 Mishra and Adhikary, 7 Usman et al, 8 Ramesh, 9 Falade et al, 10 Agarwalla and Ahmed, 11 Hosseinzadeh et al, 12 Naresh Kumar et al, 13 and Singh et al 14 studied the hydromagnetic free convective flow of a conducting fluid through a porous regime by considering various physical models of the problem. It is worth noting that for some fluids, there is a nonlinear relation between shear stress and the rate of shear strain, and such fluids are named as non‐Newtonian fluids.…”

In this study, a mathematical analysis is presented for the hydromagnetic convective flow of an incompressible, chemically reacting, and electrically and thermally conducting viscoelastic fluid through a vertical channel bounded by the porous regime under the action of an applied magnetic field with Hall current and induced magnetic field effects. The left wall of the channel is considered to be nonmagnetic, whereas the right wall of the channel is periodically magnetized. The flow within the channel is induced due to the nonuniform wall temperature and concentration, periodic pressure gradient, and periodic movement of the right wall. The method of separation of variable is used to convert the flow governing coupled partial differential equations into the ordinary differential equations that are solved analytically, and the solution for fluid velocity, induced magnetic field, temperature, and concentration is presented in a closed form. Numerical computation has been performed to demonstrate the impact of various system parameters on the fluid flow behavior. It is observed that oscillations increase the primary flow and primary induced magnetic field. Buoyancy forces have a tendency to lessen the secondary induced magnetic field. Furthermore, it is examined that magnetic diffusivity increases the primary flow, whereas it decreases the secondary flow and primary induced magnetic field.

In this study, emission incorporation and Dufour belongings are investigated for uneven magnetohydrodynamic assorted convection stream over a disposed holey moving shield with thermal emission, heat assimilation, and homogenous substance reactions subjected to changeable suction. The governing momentum equation, as well as the energy and mass diffusion equations, have analytical solutions. The Nusselt number, the Sherwood number, in addition to velocity, temperature, attentiveness, and skin friction, are computed and examined analytically and visually in order to observe the manipulate of a variety of parameters. Grashof number (Gr), modified Grashof number (Gm), magnetic parameter (M), permeability parameter (K), Prandtl number (Pr), Heat Sink (Q), Radiation parameter (F), Dufour parameter (Du), Radiation absorption constraint (R), Schmidt number (Sc), and Chemical reaction parameter (K0) are all non-dimensional parameters with different values. In porous medium, slow-moving chemical reaction fluids are the only source of the issue. In the future, researchers may look at the inertia effects of porous medium for high-velocity flows. Researchers interested in radiation absorption effects in porous media will find this a highly helpful resource.
