DOUBLE DIFFUSIVE FREE CONVECTION INDUCED BY VERTICAL WAVY SURFACE IN A DOUBLY STRATIFIED DARCY POROUS MEDIUM UNDER THE INFLUENCE OF SORET AND DUFOUR EFFECT
RÉSUMÉ
A combined heat and mass transfer process by natural convection along a vertical wavy surface immersed in a thermal and mass stratified Darcy porous medium under the influence of Soret and Dufour effects have been analyzed. The governing partial differential equations are transformed into a set of coupled boundary layer equations based on non-similarity transformation deduced by scale analysis and are solved numerically by a finite-difference scheme following the Keller-box approach. Detailed simulations are carried out to investigate the effect of varying parameters such as: the wave amplitude (a), buoyancy ratio (B ), Lewis number (Le), Soret (Sr ) and Dufour (Df ) effect coefficients, and the presence of thermal (ST ) and mass (SC ) stratification. Local and average Nusselt (Nu) number and Sherwood (Sh) number plots are presented in all cases.
