Numerical and mathematical modeling of theinjection for incompressible fluids through rigid cylindrical duct: application of melted polymers PPH

摘要

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