We present the mathematical modelling and the numerical simulation of the polymer extrusion process of hollow and non-hollow yarns. In particular, the polymeric material fow has been modelled as non-Newtonian, incompressible, isothermal and steady. We attempt to develop a possible strategy for eective die design in prole extrusion and we numerically asses the validity of the model on both academic and real industrial test cases.

Abstract
We present the mathematical modelling and the numerical simulation of the polymer extrusion process of hollow and non-hollow yarns. In particular, the polymeric material fow has been modelled as non-Newtonian, incompressible, isothermal and steady. We attempt to develop a possible strategy for eective die design in prole extrusion and we numerically asses the validity of the model on both academic and real industrial test cases.File in questo prodotto:
