In this book, an attempt is made to analyze the heat and mass transfer effects on a laminar two-dimensional steady/unsteady convection flow of a viscous incompressible and radiating Newtonian/non-Newtonian fluid past a stretching wedge/stretching sheet/thin liquid film bounded by a porous/non-porous medium, by taking viscous dissipation, uniform/non-uniform heat source/sink, activation energy, and binary chemical reaction, aligned/non-aligned magnetic strength into account. The approximate solutions are obtained by using Runge-Kutta with the shooting method. A parametric study is carried out to illustrate the behavior of the velocity, temperature, concentration, skin-friction, Nusselt number, and Sherwood number for variations in the various thermophysical and hydrodynamical parameters and are represented in figures and tables.
