摘要：利用Polyflow软件,对聚合物熔体在双转子连续混炼机内的混合过程进行了统计学分析。通过计算转子转过不同角度时的三维等温拟稳态流场,采用粒子示踪分析(PTA)方法,对聚合物熔体在双转子连续混炼机内的动态混合过程进行了可视化模拟;在此基础上对1 000条粒子的运动轨迹进行统计学分析,得出了停留时间分布、累积最大剪切速率分布、百分比粒子所受的剪切速率随时间的变化等参数,并分析了其对双转子连续混炼机混合性能的影响。
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 1 000 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 on the mixing performance in the two-rotor continuous mixer were analyzed.
