Computer Simulation of Plasticating Extruder by Chung Model |

[Computer Simulation of Plasticating Extruder by Chung Model, Japan Plastics (July extra issue), P.156 (2005)]
A unique melting model of an extruder has been developed based on experimental results by a simulative apparatus called "screw simulator" and theoretical studies on them, by Mount, Chung et al. There were discussions about the adequacy of applying the knowledge from the screw simulator to real single screw extruders. Chung and coworkers persevered in their research, and published their achievements in book form [23] in 2000. In this book, not only melting zone but also other zones, i.e. solid convey zones etc., of plasticating extruders are comprehensively discussed in detail, from unique point of view. But simulation procedure using Chung model is not mentioned specifically. The present writer developed a computer program, which simulates the melting process of a plasticating extruder using the model. The simulation program seems to give reasonable results judging from some trial calculations. In this article, theory of Chung model, its simulation program, and calculation examples are described in detail. [23] Chung, C.
