“…For nuclear reactors, the most important phenomenon called the thermophoresis deposition of the radioactive particle is used. [33][34][35] From the last few years, MHD flow along with heat and mass transmission pro has been received important consideration of the researchers and scientists, because of its wide applications in the arena of industrial and technological processes such as metal alloys, nuclear fuel, geothermal field, debris treatment, and solidifying process of the metal and many more. Besides these applications, MHD has a lot of applications and different researchers presented their studies under the consideration of MHD.…”

The purpose of this study is to examine the magnetohydrodynamic mixed convection Casson fluid flow over an inclined flat plate along with the heat source/sink. The present flow problem is considered under the assumption of the chemical reaction and thermal radiation impacts along with heat and mass transport. The leading nonlinear partial differential equations of the flow problem were renovated into the nonlinear ordinary differential equations (ODEs) with the assistance of appropriate similarity transformations and then we solved these ODEs with the employment of the bvp4c technique using the computational software MATLAB. The consequences of numerous leading parameters such as thermophoretic parameter, local temperature Grashof number, solutal Grashof number, suction parameter, magnetic field parameter, Prandtl number, chemical reaction parameter, Dufour number, Soret number, angle of inclination, radiation parameter, heat source/sink, and Casson parameter on the fluid velocity, temperature, and concentration profiles are discoursed upon and presented through different graphs. Some important key findings of the present investigation are that the temperature of the Casson fluid becomes lower for local temperature Grashof number and solutal Grashof number. It is initiated that the Casson fluid parameter increases the velocity of the fluid whereas the opposite effect is noticed in the temperature profile. Higher estimation of Prandtl number and magnetic parameter elevated the Casson fluid concentration. Finally, the skin friction coefficient, Nusselt number, and Sherwood number are calculated and tabulated. It is also examined that the Nusselt number is weakened for both the Dufour number and Soret number but the skin fraction coefficient is greater for both the Dufour number and Soret number.

In the paper, an analysis is performed to study the unsteady behaviour of micropolar fluid under mixed convection and mass transfer. In the process of study, similarity transformational approach has been considered under variable viscosity and thermal conductivity. Governing equations for the problem concerned are developed under prescribed constraints and latter on numerically solved by using Runge-Kutta method. The residual graphs represent various important parameters of the problem, viz., velocity, temperature, microrotation, concentration of the fluid and also considered the effects of Soret and Dufour within the boundary layers and analyzed.

“…Additionally, Sivaraman et al [ 25 ] considered Soret and Dufour effects on MHD free convective heat and mass transfer with thermopheresis and chemical reaction over a porous stretching surface. Recently, Srinivasacharya and Upendar [ 26 ] analyzed the flow and heat and mass transfer characteristics of the mixed convection on a vertical plate in a micropolar fluid in the presence of Soret and Dufour effects. Most recently, a boundary layer analysis has been presented to study heat and mass transfer in the laminar, viscous, and incompressible fluid past a continuously moving plate saturated in a non-Darcy porous medium in the presence of Soret and Dufour effects with temperature dependent viscosity and thermal conductivity by El-Kabeir et al [ 27 ].…”

The present paper investigates the combined effects of Soret and Dufour on free convective heat and mass transfer on the unsteady one-dimensional boundary layer flow over a vertical channel in the presence of viscous dissipation and constant suction. The governing partial differential equations are solved numerically using the implicit Crank-Nicolson method. The velocity, temperature, and concentration distributions are discussed numerically and presented through graphs. Numerical values of the skin-friction coefficient, Nusselt number, and Sherwood number at the plate are discussed numerically for various values of physical parameters and are presented through tables. It has been observed that the velocity and temperature increase with the increase in the viscous dissipation parameter and Dufour number, while an increase in Soret number causes a reduction in temperature and a rise in the velocity and concentration.
