| Abstract | We consider a two-dimensional numerical study of double diffusion natural convection in a square enclosure subjected to horizontal temperature and concentration gradients. The flow is driven by opposite thermal and solutal buoyancies. The top active vertical left side wall and fully active vertical right side wall of the enclosure are maintained at two different but uniform temperatures and concentrations. The remaining boundaries are impermeable and thermally insulated. The physical problem depends on five parameters: thermal Rayleigh number, Prandtl number, Schmidt number, buoyancy forces ratio and the aspect ratio of the enclosure. The main focus of the study is on examining the effect of Rayleigh number Rat on thermosolutal natural convection flow. The obtained results show that the increase of Rat leads to enhance heat and mass transfer rates. The flow is steady and permanent for Rat<7.10 4 . The unsteady flow appears by the formation of regular (periodic) oscillations of particles in the flow when Rat=7.10 4 . |
