Abstract: The current thesis concentrates on steady, two-dimensional and incompressible thermally stratified flows of non-Newtonian fluids over an impermeable sheet. The sheet is assumed to be linearly stretched. Powell-Eyring and Sutterby fluids are utilized in order to study the flow characteristics in the region of stagnation point under the influence of inclined MHD and mixed convection phenomena. Buongiorno’s model is considered to explore the features of Sutterby nanofluid. Conventional and generalized Fourier’s and Fick’s laws are employed to disclose the heat and mass transport processes. The aspects of thermal stratification, heat generation, thermal radiation and varying thermal conductivity are incorporated to analyse the heat transport properties. Further, chemical reaction, solutal stratification and zero flux condition are implemented to scrutinize the features of mass transportation. Constitutive coupled flow equations are converted to dimensionless form by utilizing similarity variables. Series solutions of resulting equations are computed via analytical technique namely, homotopy analysis method. The impact of eminent parameters on velocity of fluid, temperature and fluid concentration are described and analysed through graphs. Skin-friction and Nusselt number are graphically elaborated
