Effect of Geometry and Rotational Speed on the Axial Pressure Profile of a Single Screw Extrusion

Abstract


The evaluation of screw design is investigated using modeling and simulation techniques. Simulation studies were used to predict the performance of the screw under certain working conditions and flow results were developed. The pressure reached inside the barrel is directly linked to the screw geometry, set of processing conditions. The derivation of simple governing algebraic equations covering channel geometry, polymer flow rate and developed pressure were outlined to predict the response of the extruder screw. Screw rotational speed and screw design were analyzed to predict the axial pressure profile along the extruder length.
