Effect of Radiation, Chemical Reaction and Double Dispersion on Heat and Mass Transfer in Non-Darcy Free Convective Flow Available to Purchase

The present paper deals with the effect of chemical reaction, radiation and double dispersion on non-Darcy free convective heat and mass transfer from semi-infinite impermeable vertical wall in a fluid saturated porous medium. The Forchheimer extension is considered in the flow equations, while the radiation chemical reaction power-law term is considered in energy and concentration equations. The governing equations are solved numerically by means of fourth order Runge-Kutta method coupled with the double shooting technique. By giving appropriate hypothetical values for f^′(0), θ^′(0) to match with the corresponding boundary conditions at f^′(∞) θ(∞) respectively. The influence of radiation on double dispersion, solute dispersion, velocity, temperature and concentration profiles as well as heat transfer and mass transfer rates are discussed.
