Abstract

Thermally driven steady mixed convective chemically reacting flow of an electrically conducting viscous incompressible fluid over a linearly stretching sheet in the presence of suction/injection, heat generation/absorption and thermal radiation is investigated. The governing nonlinear equations are transformed into ordinary differential equations using the similarity transformation, and linearized using the perturbation series expansions. The resulting linear similarity equations are solved semi-analytically using the Mathematica 9.0 software. Solutions of the concentration, temperature, velocity, Nusselt number, Sherwood number and skin friction are obtained, and presented graphically to illustrate the effects of the various parameters on the dependent flow variables. The results are extensively discussed. Furthermore, the results obtained are bench-marked with some of those obtained in the earlier studies in literature, and are found to be in consonance.
