Abstract: Three-dimensional simulation and mixing analysis were conducted for melt flow in screw groove of differential twin screw extruder using Polyflow. In view of shear rate, stretch rate, and mixing index, the mixing with differential ratio of 5:1.was better than that with 4:1.

Key words: differential twin screw extruder, three-dimensional flow, mixing, numerical simulation
