Abstract
In this paper we simulate the flow of a Newtonian fluid in a tangentia l counter-rotating twin screw extruder using a cylindrical coordinate lubrication theory model. Special attention is given to the material f lows leading to mixing specially to inter-screw and backward leakage b etween the screws, and how they vary with process conditions.
