The effect of radiation on the flow over a stretching plate of an optically thin gray, viscous and incompressible fluid is studied. The fluid viscosity is assumed to vary as an inverse linear function of the temperature. The partial differential equations (PDEs) and their boundary conditions, describing the problem under consideration, are dimensionalized and the numerical solution is obtained by using the finite volume discretization methodology which is suitable for fluid mechanics applications. The numerical results for the velocity and temperature profiles are shown for different dimensionless parameters entering the problem under consideration, such as the temperature parameter, θ r , the radiation parameter, S, and the Prandtl number, Pr. The numerical results indicate a strong influence of these parameters on the non-dimensional velocity and temperature profiles in the boundary layer.

“…Chamkha and Aly [6] studied the stagnation point flow of a polar fluid over a stretching surface in a porous medium with thermo diffusion and diffusion thermo effects. Pal and Mondal [7] discussed the unsteady MHD non-Darcy mixed convective flow towards a stretching surface with heat and mass transfer effects. In this study, they concluded that temperature profiles increases with Dufour number.…”

Abstract:The problem of an unsteady MHD Casson fluid flow towards a stretching surface with cross diffusion effects is considered. The governing partial differential equations are converted into a set of nonlinear coupled ordinary differential equations with the help of suitable similarity transformations. Further, these equations have been solved numerically by using Runge-Kutta fourth order method along with shooting technique. Finally, we studied the influence of various non-dimensional governing parameters on the flow field through graphs and tables. Results indicate that Dufour and Soret numbers have tendency to enhance the fluid velocity. It is also found that Soret number enhances the heat transfer rate where as an opposite result is observed with Casson parameter. A comparison of the present results with the previous literature is also tabulated to show the accuracy of the results.

Abstract. The main aim of this study is to present the e ects of Soret & Dufour on MHD mixed convection ow of a viscous uid towards a vertical plate embedded in a porous medium in the existence of slip, radiation and chemical reaction. The numerical solutions are acquired using shooting method, and the governing equations are reformed into ordinary di erential equations by similarity transformation. The present results compared with previously presented works are found in good agreement on several distinct cases. The e ects of di erent parameters on velocity, temperature, and concentration distributions are illustrated graphically. The variation of diverse parameters on local skin friction, rates of heat, and mass transfer is obtainable in tabular arrangement. The velocity and temperature increase on increasing the Dufour parameter, and the concentration pro les decrease when chemical reaction parameter increases.
