We have studied the numerical solutions
of steady MHD free convective flow of a viscous incompressible electrically
conducting fluid past over a porous substrate attached to a non-linearly
stretching sheet embedded in an extended Darcy-Forchheimer porous medium, in
the presence of a uniform transverse magnetic field with viscous dissipation.
The boundary layer equations are transformed to ordinary differential equations
with the help of similarity transformations and we have solved these equations
with the help of MATLAB program. The numerical results obtained for velocity
profile, temperature profile, skin-friction and Nusselt number for various
parameters like Magnetic parameter, permeability parameter, Forchheimer
parameter etc. are discussed and presented through graphs.
