An approximate numerical solution for the steady laminar boundarylayerflow over a wall of the wedge in the presence of species concentration and mass diffusion has beenobtained by solving the governing equations using the numerical technique. The fluid is assumed to beviscous and incompressible. Numerical calculations are carried out for different values of dimensionlessparameters and an analysis of the results obtained shows that the flow field is influenced appreciably by themagnetic effect, the buoyancy ratio between species and thermal diffusion and suction/injection at the wallsurface. Effects of these major parameters on transport behaviors are investigated methodically and typicalresults are illustrated to reveal the tendency of the solutions. Representative results are presented for thevelocity, temperature, and concentration distributions, as well as the local skin-friction coefficient and skinfriction.
