Abstract

Abstract: Statistical analysis was performed on the mixing process of polymer melts in a two-rotor continuous mixer using Polyflow software. Based on the 3-D isothermal time-dependent flow fields calculated at different rotational angles of rotors, dynamic mixing processes of polymer melts in the two-rotor continuous mixer were simulated through particle tracking analysis (PTA). By statistical treatment of 1000 particle trajectories, the resident time distribution, cumulative max-shear-stress distribution, and percentage of shear stress as a function of time were obtained. Furthermore，the influences of these parameters to the mixing performance in a two-rotor continuous mixer were analyzed.

Key words: two-rotor continuous mixer, numerical simulation, statistical analysis, particle tracking analysis.
