In the current thesis, the flow of Non Newtonian fluid over variable thicker surface is investigated. For a Non-Newtonian fluid, the system is formulated by using both upper and lower convected Maxwell model. The mathematical formulation of the problems leads to partial differential equations (PDEs) which are first converted into ordinary differential equations (ODEs) via suitable similarity transformations and then solved numerically through Runge-Kutta method. The results are evaluated in velocity and temperature profiles and discussed in graphical form.
