Flow barrier-embedded mixing

M 80] [P 70] From prior experience with the chaotic screw extruder, it was estimated that the presence of the barrier structures in the barrier-embedded mixer accounts for about a 10% reduction in flow rate as compared with the slanted grooved mixer [58], Thus, a large mixing improvement is given at the cost of only a small reduction in flow rate.

M 80] [P 70] Cross-sectional images of the flow patterns, gained by confocal microscopy, demonstrate the interfacial stretching and hence are indicative of mixing in the barrier-embedded mixer [58], At the non-barrier entrance structure clearly the helical flow induced by the slanted grooves is evident. In the barrier...
