A New Solution for Viscosity Identification in a Polymer Production Line via Convection Analysis
Résumé
Some studies have demonstrated the interest of temperature measurements for in-line rheometry. Both viscous dissipation and convection can be used in viscosity identification via inverse method. However, the inlet temperature (of a device downstream of a screw) in a polymer production line has also been observed to be less under control. To overcome the inlet temperature uncertainties during an in-line thermo-rheological characterization and to further apply a differential convection method for an injection molding process, a concept of device designing is proposed in this work. An analytical and numerical investigation proves that the proposed concept can provide information on the viscosity of the material via thermal measurements, despite a poorly known inlet temperature
