Abstract :
This study presents a numerical analysis on the effects of Soret, variable thermal conductivity, viscous-Ohmic
dissipation, non-uniform heat sources, on steady two-dimensional hydromagnetic mixed convective heat and
mass transfer flow of a micropolar fluid over a stretching sheet embedded in a non-Darcian porous medium
with thermal radiation and chemical reaction. The governing differential equations are transformed into a set
of non-linear coupled ordinary differential equations which are then solved numerically by using the fifthorder Runge-Kutta-Fehlberg method with shooting technique. Numerical solutions are obtained for the
velocity, angular velocity, temperature and concentration profiles for various parametric values, and then
results are presented graphically as well as skin-friction coefficient, and also local Nusselt number and local
Sherwood number for different physical parameters are shown graphically and in tabular form. A critical
analysis with earlier published papers was done, and the results were found to be in accordance with each
other.
