气液界面化学活性颗粒的模拟

Modeling of chemically active particles at an air-liquid interface

Shun Imamura, Toshihiro Kawakatsu

摘要:

从理论上研究了气液界面上化学活性粒子的集体运动,并将其视为一个动态自组织问题。基于物理的考虑,我们提出了一个极小模型的自推进颗粒相结合的流体动力学相互作用,毛细管相互作用,驱动力的Marangoni效应,和Marangoni流。我们的模型已经成功地捕捉到了化学活性粒子的特征,这些粒子代表了动态的自组织状态,如晶态、链状、类液态和扩散态。

英文摘要:

The collective motion of chemically active particles at an air-liquid interface is studied theoretically as a dynamic self-organization problem. Based on a physical consideration, we propose a minimal model for self-propelled particles by combining hydrodynamic interaction, capillary interaction, driving force by Marangoni effect, and Marangoni flow. Our model has successfully captured the features of chemically active particles, that represent dynamic self-organized states such as crystalline, chain, liquid-like and spreading states.
