“…Seth et al studied the unsteady MHD free natural convection and radiation effect on the flow of fluids over a moving vertically accelerated plate in the presence of chemical reaction. Apart from this study, many researchers had contributed to studying the unsteady MHD flow of Casson fluids past a flat plate with different boundary conditions. Vanita and Kumar studied the induced magnetic field effect over a vertical cone.…”

In this paper, an attempt has been made to analyze the effects of various parameters, such as Soret and Dufour effects, chemical reaction, magnetic field, porosity on the fluid flow, and heat and mass transfer of an unsteady Casson fluid flow past a flat plate. Convective boundary conditions in heat and mass transfer and slip constant on velocity have been taken into account for analysis. The governing equations of the model have been solved numerically using the MATLAB program bvp4c. The impact of various parameters of the model on the velocity, temperature, and concentration profiles has been analyzed through different graphs. To get an insight into the physical quantities of engineering interest, viz, skin friction, Sherwood number, and Nusselt number, their numerical values have been computed for various parameters. The range of the parameters used in numerical computations are Pr (0.3-0.8), ( β 0.5-1.5), M (1-5), A (0.5-1.5), L (0.1-0.9) 0 , D (0.2-4) f , Sr (0.3-6.3), and Sc (0.05-0.15). It has been noticed from the tabulated values that the skin friction gets enhanced with the increase in the thermal and solutal Grashof number,whereas its reverse effects have been observed with an increase in the Biot number. In limiting case, the present study is also compared with the available results in the literature.

The aim this paper is to study An Unsteady MHD free convection flow of casson fluid past an exponentially accelerated infinite vertical plate through porous media in the presence of thermal radiation and heat source or sink. Also the first order chemical reactions are taking into an account .At the same time, the plate temperature and concentration of the plate are raised to * * The system of partial differential equation are solved by the analytically by using Laplace Transform Technique procedure. The results for various fields like velocity, temperature, and concentration are displayed and discussed. Numerical values of the skin friction coefficient, the Nusselt number and the Sherwood number for different values of physical parameters are constructed and analyzed. The convergence of the series solutions is examined. The velocity profiles decrease with increases the values of magnetic parameter, Prandtl number, heat source, thermal radiation and Casson parameter.
