CFD simulation of plastics plasticizing in an extruder with a continuously grooved cylinder and barrier screw
At the Institute of Product Engineering at the University of Duisburg-Essen a new material model for CFD simulation has been developed, which assists to reflect virtually the melting processes in plastic processing machines. The model allows the parallel consistent rheological and thermodynamic illustration of solids and melt in just one continuum and thus enables the use of common CFD solvers. The use of the model to calculate the plasticizing of a PE-HD material in a 100 mm extruder with barrier screw and optionally smooth or continuously grooved cylinder demonstrates the power and ease of use of these innovative CFD technology.
The Journal of Plastics Technology is a peer reviewed internet periodical published under the auspices of the Scientific Alliance of Polymer Technology (WAK)
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
The Journal of Plastics Technology is indexed in SCOPUS, the largest abstract and citation database of peer-reviewed literature.
