Abstract
The dynamics of fluid flow over a stretching or shrinking surface is important in many practical applications such as extrusion of plastic sheets, paper production, glass blowing, metal spinning, drawing plastic films. There are many mechanisms that can be responsible for the movement of a fluid. These mechanisms include, the pressure gradient, movement of surface the fluid is resting upon or the surfaces the fluid is contained in and buoyancy force resulting due to density gradients. Convection III porous media IS important III engmeenng applications such as geothern1al systems, solid matrix heat exchangers, thermal insulations, oil extraction and store of nuclear waste materials. Convection in porous media can also be applied to underground coal gasification, ground water hydrology, iron blast furnaces, wall cooled catalytic reactors, solar power collectors, energy efficient drying processes, cooling of nuclear fuel in shipping flasks and cooling of electronic equipments. The study of chemical reaction with heat transfer in porous medium has important engineering applications such as tubular reactors, oxidation of solid materials and synthesis of ceramic materials. The flow of non-Newtonian fluids has gained considerable importance because of its applications in various branches of science, engineering and technology such as material processing, chemical industries, geophysics, and bio-engineering. The main goal of this thesis is to study the flow of Newtonian and non-Newtonian fluids with heat and mass transfer through different geometric shapes. We are considering a flow over horizontal/vertical surfaces, shrinking or stretching and inside a vertical channel.
