Flow and Diffusion of Chemically Reactive Species over a Nonlinearly Stretching Sheet Immersed in a Porous Medium

The flow and mass transfer of a chemically reactive species over a nonlinearly stretching sheet in a porous medium is considered. The boundary layer theory and the similarity procedure are used to obtain a system of nonlinear ordinary differential equations. A feasible approximate analytical solution for the system is obtained and the influences of the physical parameters on the flow and mass transfer characteristics are analyzed. The permeability parameter reduces the velocity profiles and increases the momentum and concentration boundary layers thickness. The destructive chemical reaction reduces the concentration boundary layers.
