Abstract
Our melted polymer is modeled by incompressible non-Newtonian fluids. The mathematical formulation leads to very complex equations. These complexities can arise, on the one hand, from the law of behavior of the fluid of interest (Arrhenius model) and the nature of the flow and on the other hand the nature of the wall considered. We are interested in this study to establish a numerical code to study the flow of molten polymers in rigid cylindrical ducts. Using an iterative numerical finite volume method, we determine the axial profile of the velocity and the temperature.
