Abstract
The fluid flow and heat transfer in the extrusion of polymeric materials in a twin-screw extruder was studied numerically by using the finite volume method. In the mathematical model, the coordinate system is fixed to the screw so that it is held stationary and the barrel is moved to simplify the complicated geometry. The screw channel of a twin screw extruder is approximated as two regions: translation and intermeshing. An experimental investigation of the velocity profiles in the translation region of a self-wiping twin screw extruder, which is often used in practical applications, was carried out using a Laser Doppler Anemometer. The numerically predicted velocity profiles are compared with those from the experiments, yielding fairly close agreement.
