SINOPSIS

This paper presents a numerical investigation of double-diffusive free convective heat and mass transfer of a chemically reacting fluid flowing through a non-Darcian porous medium adjacent to a vertical surface. The Forchheimer extension is considered in the flow equation, chemical reaction is considered in the concentration equation. The governing equations are solved numerically by means of the fourth-order Rungeminus;Kutta method coupled with the double-shooting technique. The effects of thermal dispersion, solute dispersion, velocity, temperature, and concentration profiles as well as heat and mass transfer rates are discussed.
