## Abstract

The prediction of heat and mass transfer characteristics about mixed convection over an exponentially stretching surface in Newtonian fluids is very important due to its practical engineering and industrial applications, such as glass-fiber production, wire drawing, paper production, plastic sheets, metal and polymer processing industries and many others. Realizing the increasing technical applications of magnetohydrodynamics (MHD) effects, the problem of MHD boundary layer flow over an exponentially stretching sheet has been studied by a number of researchers. The Newtonian fluid flow equations constitute a coupled system of equations and are complicated. In spite of this, in this dissertation an attempt has been made to study the steady two-dimensional laminar flow of a viscous incompressible electrically conducting fluid over an exponentially stretching sheet in the presence of cross-diffusion effects. The dissertation consists of THREE chapters. The first chapter (i.e. Chapter - 1) provides an introduction to the concepts in Newtonian fluid, MHD, heat and mass transfer and a review of the relevant literature. The second chapter (i.e. Chapter - 2) deals with mixed convection heat and mass transfer over an exponentially stretching surface embedded in the Newtonian fluid in the presence of MHD, Soret and Dufour effects. In all the cases of the chapter the governing equations are transformed into a set of nonlinear non-homogenous differential equations using the local-similarity transformations. The transformed boundary layer ordinary differential equations are solved numerically using the shooting and matching technique. The effects of MHD parameter, Soret and Dufour numbers together with mixed convection parameter on the velocity, temperature, concentration, skin riction coefficient, heat transfer rate and mass transfer rate are considered. The last chapter (i.e. Chapter - 3) gives a summary and overall conclusion.
