Notes:
The prediction and measurement off the developing radial temperature profile in a single-screw extruder is essential since excessive extrudate temperature and poor temperature uniformity at the die affect the quality of coextrusion and film/sheet extrusion processes. A finite-difference scheme is used to predict the development of the radial temperature profile in the metering section of a single-screw extruder for power-law fluids. A finite-element analysis of the flow around the screw-tip transposes this temperature profile onto an on-line temperature measuring device consisting of 10 thermocouples for a comparison of numerical results with experimental data on polycarbonates.
