Experimental deep‐channel velocity profiles and operating characteristics for a single‐screw extruder

Abstract Data have been obtained on the operation of a deep‐channel single‐screw extruder, pumping a Newtonian liquid under isothermal, developed flow conditions. Flow rate, screw speed, and pressure gradient characteristics were measured, and a tracer particle technique was employed to determine channel velocity profiles. The data were required for the testing and development of a computer model for flow in the extruder, which takes into consideration channel curvature. Results confirm the correctness of the computer solutions previously reported.
