Abstract

A new versatile on-line rheometer has been developed for monitoring process viscosities. The principle of this rheometer is based upon measuring the pressure differential across one flight of a special extruder wherein the helix is cut in the barrel rather than in the screw. On-line data from the new rheometer agree well with off-line capillary rheometer data. The new rheometer can also handle fluids beyond the capabilities of conventional capillary or slit rheometers. The relationship of wall shear rate for closed Couette flow has been determined for power law fluids.
