Abstract

Chemical and Soret effects on Unsteady MHD (Magnetohydrodynamics) free convective flow of an incompressible, dissipative fluid flow past an accelerated vertical plate in presence of inclined magnetic field through porous medium is investigated under Joule effect. The main aim of the present paper is to investigate unsteady MHD free convection boundary layer flow of a Newtonian fluid with chemical and Soret effects on flow past an accelerated vertical plate in presence of inclined magnetic field with joule effect. The governing partial differential equations have been solved numerically; using finite difference technique. The numerical solutions are obtained for the velocity, temperature, and concentration distributions. The effects of system parameters, such as the Chemical reaction, Soret number, thermal Grashoff number, modified Grashoff number, Eckert number, Angle of inclination and magnetic field parameter on the flow fields are thoroughly presented through graphs and tables. Here it is observed that the velocity increases with the thermal, modified Grashoff numbers and with Eckert number. The temperature distribution increases with the increase of Eckert number and the heat absorption, whereas for high radiation and with the increase of thermal and modified Grashoff numbers, temperature decrease is observed. With the increase of the chemical reaction parameter, Schmidt number, Soret number, Eckert number and time ,the concentration distribution decrease is observed.
