MHD Viscoelastic Fluid Flow over a Vertical Stretching sheet with nth order of chemical reaction

We have investigated heat and mass transfer in a steady two-dimensional magneto hydrodynamic viscoelastic fluid flow over a stretching vertical surface with nth order chemical reaction. The two-dimensional boundary-layer governing partial differential equations are reduced to ordinary differential equations by using Nactsheim-Swigert shooting technique with sixth order Runge-Kutta iteration Method. e ordinary differential forms of momentum, energy and concentration equations obtained by local similarity transformation are highly nonlinear. The effects of different flow parameters like magnetic field parameter, Prandtl number, buoyancy parameter, Soret number, Dufour number on velocity, temperature and concentration profiles are plotted and discussed numerically and graphically.
