In this book an attempt is made to analyze the heat and mass transfer effects on a viscous in-compressible two dimensional steady/unsteady convective flow of a Newtonian/non-Newtonian fluid past a stretching sheet bounded by a porous/nonporous medium by taking viscous dissipation, linear/non-linear thermal radiation, uniform/non-uniform heat source/sink, Activation energy and Binary Chemical reaction with aligned/non-aligned magnetic strength into account. The governing equations are coupled and non-linear. An exact solutions are not possible for such problems, approximate solutions are...
