Abstract:

In the study on twin-screw extrusion process of polymers, the numerical simulation method can overcome the limitations of traditional experimental methods and provide important guidance for design and processing of twin-screw extruder. This paper reviewed the research progress in the numerical simulation of twin-screw extrusion process at home and abroad in recent years, and also introduced the advantages and disadvantages of mathematical description of the extrusion process by the one?dimensional mathematical model and three?dimensional mathematical model. The relevant research progress was summarized in the aspects of flow field characteristics, transient mixing performance, residence time distribution and reactive extrusion in the twin-screw extruder. Moreover, the future development direction of the numerical simulation of twin-screw extrusion process was prospected.
