Modelling of twin screw reactive extrusion: challenges and applications
Résumé
Numerical modelling of twin screw reactive extrusion is a very efficient tool to understand and master the complex interactions between the numerous variables of the process. However, it remains a real challenge, as it necessitates to couple flow simulation in complex geometries, reaction kinetics and evolutionary rheological behavior. After a presentation of the general principles of reactive extrusion modelling, we will focus on the models we developed, based on continuum mechanics. Different examples of applications are presented for illustrating the interest of this method.
