A Composite Model for Melting,Pressure and Fill Factor Profiles in a Metered Fed Closely Intermeshing Counter-rotating Twin Screw Extruder

摘要

A composite model of solids conveying,melting and melt flow in a closely intermeshing counter-rotating twin-screw extruder of modular design has been developed.This is based on combining melt conveying models with new melting and solids conveying models.Computations are made for axial fill factor,pressure,temperature and melting profiles.The results are compared with experiment.
