This paper is concerned with Newtonian flow in a counter‐rotating non‐intermeshing twin‐screw extruder. Both the matched and the mismatched screw flight configurations are considered. A three‐dimensional analysis of the pressure flow through the complete extruder cross‐section is included. The model predictions agree well with the experimental data. Computed examples are given to illustrate the utility of this work.
