Abstract: Abstract It is of great importance in designing extruders to predict the screw characteristics, that is, the throughput in terms of the screw speed and the pressure gradient along the down‐channel direction. The screw characteristics depend on the extruder geometry, the operating conditions, and material properties of non‐Newtonian fluids. This paper suggests a simple approach to determining the screw characteristics for a three‐dimensional flow in a channel with a finite aspect ratio (ratio of a width to a d…
