For the non-Newtonian fluid, five parameters contained Carreau Model is used. To achieve the goal, thesis is divided into three chapters. One chapter contains the basic definitions and some terminologies. Chapter two contains basic governing equations which are used for flow problem. In the last chapter, the mathematical model is developed by using equations of chapter two. The solution of this model is obtained by RK-method. The results are displayed in form of velocity and temperature profile for discussion.enDepartment of MathematicsFA19MathematicsNon-Newtonian FluidCarreau ModelDr. Mohsan HassanThesis
