The chaotic mixing process in a continuous mixer plays an important role and has an essential influence on the performance of prepared materials. To reveal how a polymeric drop experienced the chaotic mixing and give more specific analysis about the chaotic mixing, the morphology development of a single drop was traced and recorded with an on-line visualization system. The drop would undergo elongation deformation, reorientation, and folding process, which were the typical signs of chaotic mixing. The elongation deformation was an important precondition for drop experiencing the reorientation and folding process and mainly existed in the region near the barrier, rotor tip clearance, and wedgelike region. The reorientation and folding process mostly appeared in the region near the rotor flat and interaction window. Besides, the erosion process of the drop was observed at the initial stage under lower rotor rotation speed. The chaotic mixing always held the dominant place in continuous mixer although the rotor rotation speed and drop viscoelasticity were adjusted. In this work, the chaotic mixing in a continuous mixer was dynamically presented. The dynamical results would give a more real and visual understanding of the chaotic mixing.

跟踪聚合物液滴形态发展的连续混合器混沌混合分析

连续混合器中的混沌混合过程起着重要作用，并且对所制备材料的性能具有重要影响。为了揭示聚合物液滴如何经历混沌混合并提供关于混沌混合的更具体分析，使用在线可视化系统跟踪并记录了单个液滴的形态发展。液滴将经历伸长变形，重新定向和折叠过程，这是混乱混合的典型标志。伸长变形是液滴经历重新取向和折叠过程的重要前提，并且主要存在于屏障附近，转子尖端间隙和楔形区域。重新定向和折叠过程主要出现在转子平面和相互作用窗口附近的区域。除了，在较低的转子转速下，在初始阶段观察到液滴的侵蚀过程。尽管调节了转子的转速和液滴的粘弹性，但在连续混合器中，混沌混合始终占据主导地位。在这项工作中，动态地介绍了连续混合器中的混沌混合。动力学结果将为混沌混合提供更真实和视觉上的理解。
