USING EXTREME BARREL DIAMETERS TO VERIFY THE NUMERICAL SIMULATION OF SINGLE-SCREWEXTRUDERS Mark A. Spalding, The Dow Chemical Company, Midland, MI; Greg A. Campbell, Fredrick Carlson, and Kambiz Nazrisdoust Clarkson University, Potsdam, NY

Abstract

Numerous models exist for the prediction of pressure profiles in the metering section of single-screw extruders. For the most part, these models were verified using experimental data from small diameter extruders. Verification using data from large diameter machines, however, has not been fully explored due to the lack of experimental data. The analysis here will show the effect of barrel diameter on the ability of a model to predict pressure profiles in the metering channel.
