Modeling of twin screw extrusion. Part 2, Model verification

Abstract

A comprehensive computer model for counter-rotating twin-screw extrusion has been verified on the base of experimental and simulation studies for closely intermeshing strave fed extrusion (Fig. 3). Melting behavior of the polymer, pressure and temperature profiles as well as fill factor were evaluated at various flow rates and screw speeds (Fig. 4-9). The agreement of predictions and observations was satisfactory (Fig. 10-12).
