  • Analytical and numerical study of double diffusive parallel flow induced in a vertical porous layer subjected to constant heat and mass fluxes
    Amahmid, Abdelkhalk ; Hasnaoui, Mohammed ; Douamna, Samira
    Multiplicity of solutions induced by opposing thermal and solutal buoyancy forces in a vertical porous layer subject to horizontal fluxes of heat and mass is studied analytically and numerically ... using the Darcy model. The governing parameters for the problem are the Rayleigh number, R_T, the Lewis number, Le, the buoyancy ratio, N and the aspect ratio of the porous matrix, A. The analytical solution developed is based on the parallel flow approximation. The effect of the parameters Le and N on the multiplicity of solutions is studied. It is demonstrated, in this study, that numerical multiple steady state solutions, that agree very well with the analytical ones, are possible when the aspect ratio of the porous layer is large enough. It is also found that the heat and mass transfer depend strongly on the solution considered when multiple steady states are existing.
