Influence of Chemical Reaction, Magnetic Field, Heat Source on Heat and Mass Transfer by Free Convection Flow over a Stretching Cone Embedded in a Porous Medium Considering Soret and Dufour Effects

Abstract

Heat and mass transfer characteristics of free convection flow over a stretching cone embedded in a porous medium subjected to a chemical reaction, magnetic field, heat source are investigated numerically by taking into account the Soret and Dufour effects. The velocity, temperature and concentration profiles are drawn for various values of  heat source parameter, pressure work parameter, magnetic field parameter, Rayleigh number, chemical reaction parameter, buoyancy ratio parameter, Prandtl number, Schmidt number, thermal stratification parameter, wall concentration exponent, Soret and Dufour numbers. Numerical results of rate of heat and mass transfer for different parameters are presented in tabular form and the results are depicted graphically.
