Numerical simulation of a single‐screw plasticating extruder

Abstract A fully‐predictive steady‐state computer model has been developed for a single‐screw plasticating extruder. Included in the model are a model for solids flow in the feed hopper; a variation of the Darnell and Mol model for the solids conveying zone; a variation of Tadmor's melting model for the melting zone; an implicit finite difference solution of the mass, momentum, and energy conservation equations for the melt‐conveying zone of …
