Abstract

A computational experiment was carried out on the basis of the created model of melt flow with undermelted granules in a straight annular channel, which takes into account the design characteristics of a pilot-industrial disk extruder. A polymer composition based on high-pressure polyethylene (PE 15803-020) was chosen as a model object. The calculation procedure is presented in an analytical form at disk speeds of minimum value – 120, nominal value – 150, and maximum value – 180 rpm
