Abstract
This paper reports the mathematical model of the heat and mass transfer in a non-Newtonian fluid flow through a permeable nonlinear stretching vertical wall in the presence of such effects as exothermically reacting, heat generation/absorption, thermal radiation, and heat and mass fluxes. A similarity transformation is used to reduce the controlling partial differential equations (PDEs) into ordinary ones, which are solved numerically by an efficient numerical shooting technique with a fourth-fifth order Runge-Kutta method. Numerical results for the temperature and concentration profiles as well as for the local skin friction, Nusselt number, and Sherwood number are obtained and depicted graphically for different parametric conditions to illustrate interesting aspects of the solution. It is found that the source parameter enhances the distribution at all points, and heavier species cause a lower concentration level near the concentration boundary layer.
