Abstract Dispersive mixing is an important indicator for conventional co-rotating twin-screw extruders. In this work, a new asymmetric extruder was developed to improve dispersive mixing. An aqueous solution of sodium carboxymethyl cellulose (CMC-Na) employed as matrix fluid, and the red oil-based ink used tracer. A response surface model constructed predict average diameter droplets in terms feed rate, screw speed, baffle height, then corresponding optimal solutions were obtained. Visualization experiments indicated that gap regions between barrel are mainly responsible tracers’ breakup. Particle image velocimetry further confirmed high velocity appeared these resulted shear rates, especially height 15.5 mm, where linked turned up.
