研究流场中高分子溶液的结晶行为是一个复杂的问题。应用格子链动态蒙特卡洛模拟研究泊肃叶流场中高分子溶液的结晶。通过非对称性抽样引入泊肃叶流场,改变流场的大小考察其对高分子溶液结晶的影响。结果表明流场的大小对结晶速度的影响不是单一的,而是存在一个临界值,流场大小低于该临界值则加速结晶,高于该临界值,则流场增大反而使结晶速度变慢。在外加流场中高分子结晶沿着流场方向明显取向。
Studying the crystallization behavior of polymer solution in flow field is a complex problem. Dynamic Monte Carlo Simulation Using Lattice Chains to Study Crystallization of Polymeric Solution in Parker Leaf. The asymmetric sampling was used to introduce Poiseuille flow field, and its influence on the crystallization of polymer solution was investigated by changing the size of flow field. The results show that the size of the flow field has not a single effect on the crystallization rate, but has a critical value. When the flow field size is lower than the critical value, the crystallization accelerates. If the flow field is larger than the critical value, the flow field increases and the crystallization speed changes SLOW. In the applied flow field, the polymer crystal is obviously oriented along the flow field.
