Thermosolutal natural convection combined with Soret effect within a vertical shallow porous Darcy enclosure is the main concern of this work. Neumann boundary conditions for both temperature and concentration are applied on the vertical walls of the cavity. The study, conducted analytically and numerically, is focused on the boundary layer regime. The present problem is governed by the thermal Rayleigh number RT, the Lewis number Le, the buoyancy ratio N, the aspect ratio of the enclosure Ar and the Soret parameter SP. The effect of the governing parameters on fluid flow and heat and mass transfer characteristics is examined in this study.
