    Abstract

    The quality of distributive mixing is evaluated via an entropic measure of color homogeneity. We first illustrate this technique in a numerically built rectangular channel representing the unwounded channel of a single screw extruder. We also apply this method for assessing mixing quality of experimentally obtained samples when mixing a color concentrate in ABS resin in a single screw extruder. We discuss application of this technique in numerical simulations of processing equipment.
