Abstract
The flow characteristics of Newtonian and non-Newtonian fluids in a roller die are simulated. Both pre-form and Tmanifold entry regions are considered. Calculations are made using a modified Flow Analysis Network procedure. We take into consideration the interaction of roller dies with the screw extruders that feed them. We show operating conditions that can cause starvation to develop in screw extruders feeding roller dies.
