A Model of 2 Dimensional Flow in a Twin Screw Mix-Extruder Kneading Disc Using a Full 2 Dimensional Solution of the Flow Equations

Abstract

A method of modelling 2 dimensional flow in a kneading disc of a screw mix-extruder(SME) has been developed which involves solving the differential equations for flow directly, without the approximation used previously which effectively reduced the flow to 1 dimension. The pressure and velocity distributions obtained appear to be realistic, and agree reasonably well with results obtained previously. The model should be able to be readily expanded to 3 dimensions.
