The aim of this study is to examine the impact of the thermo-diffusion phenomenon, known as the Soret effect, on double diffusive natural convection induced in a horizontal Darcy porous enclosure saturated with a binary mixture. The considered porous cavity is subject to uniform lateral heat and mass fluxes. The long horizontal walls of this medium are considered adiabatic and impermeable to mass transfer. The Soret effect on the fluid flow properties and heat and mass transfer characteristics is discussed here for a particular situation characterized by a specific relationship between the solutal to thermal buoyancy forces ratio and the Soret parameter for which the rest state is a solution of the problem.
