Non-Darcy-Benard Double Diffusive Marangoni Convection with Dufour Effect in a Two-Layer System

Two - component / Double Diffusive Marangoni (DDM) convection with Dufour effects, in a two-layered system, has been studied analytically by using Darcy – Brinkmann Model. For fluid layer, the upper boundary is free surface tension depending on both temperature and concentration, for porous layer lower rigid boundaries are insulating to heat mass. At interface, normal velocity, stress, shear mass, mass flux, heat, flux assumed be continuous. The effect of different physical parameters DDM investigated detail results presented graphically. parameter, which plays vital role diffusion-thermal process, when energy due gradient appears, two- explored.
