| Summary: | This study presents a mathematical analysis of a hydromagnetic boundary layer
flow, heat and mass transfer characteristics on steady twodimensional flow of
a micropolar fluid over a stretching sheet embedded in a non-Darcian porous
medium with uniform magnetic field in the presence of thermal radiation. The
governing system of partial differential equations is first transformed into
a system of non- linear ordinary differential equation using the usual
similarity transformation. The resulting coupled non-linear ordinary
differential equations are then solved using perturbation technique. With the
help of graphs, the effects of the various important parameters entering into
the problem on the velocity, temperature and concentration fields within the
boundary layer are separately discussed. The effects of the pertinent
parameters on the wall temperature, wall solutal concentration, skin friction
coefficient and the rate of heat and mass transfer are presented numerically
in tabular form. The results obtained showed that these parameters have
significant influence on the flow.
