摘要: A numerical study on combined heat and mass transfer by natural convection adjacent to a vertical surface in thermally stratified fluid saturated square porous enclosure is reported. The Galerkin finite element method graded grid system has been employed the computations. When thermal species diffusion coefficients are equal, increasing levels of stratification significantly influence both aiding opposing flow structures their concomitant temperature fields. For unequal changes concentration field structure seen be more prominent. Nusselt (Nu) Sherwood (Sh) number data have presented for various values Lewis (Le), buoyancy ratio (B), Rayleigh ( Ra ) at (S).
