Modelling Flow in an Intermeshing Co-rotating Twin Screw Extruder: Flow in Kneading Discs
-
W. Szydlowski
Abstract
A model for simulation of flow in an intermeshing kneading disc region of corotating twin screw extruder is presented. This is based on hydrodynamic lubrication theory for a Newtonian fluid. Numerical procedures are used to compute the pressure distribution and flow field in the kneading disc region. The influence of staggering angle, nip clearance, screw speed and throughput rate are investigated.
