【 摘 要 】

Numerical computation has been carried out for the study of non-linear coupled partial differential equations for combined effects of Soret, Dufour and variable fluid properties like variable viscosity and variable permeability on thermal and diffusion mixed convection flow fluid through porous media over an accelerating surface. The study has been carried out for other additional terms like viscous dissipation and ohmic effect due to the presence of viscous and porous media. By applying the shooting method, we have drawn the numerical results for the flow characteristics like velocity, temperature and concentration for the Soret and Dufour effects on mixed( free and forced) convective flow for various non-dimensional parameters of the problem. Our computational results are compared with the earlier works in the absence of the additional terms and effects on the physical system and found to be good agreement.
