Numerical Analysis of Mixing Behavior in the Extruder

Abstract

Introduce the simulation technology of the latest of extrusion machine for the polymer processing. The Flow analysis network (FAN) method is possible to analyze the extruder entire region based on the two dimensional calculation. The latest technology of the FAN method is applied to three dimensional field by a 2D-3D coupling technique. FEM and FVM analyses apply to prediction of detail screw mixing behavior by three dimensional calculation. Particle method is newly technology for polymer processing (high viscosity non-Newtonian fluid). Recently, DEM-MPS coupling analyze technique is developed and it shows qualitative prediction for polymer plasticization in the twin screw extruder.
