我们提出了一个由界面张力不均匀引起的液滴自发运动模型。该模型是由系统的拉格朗日变分得到的，我们使用时间离散的Morse流格式进行了数值模拟。我们的模型可以自然地模拟单个液滴的动力学，也可以模拟多个液滴的动力学，其中每个液滴的体积是守恒的。我们再现了液滴的弹道运动和裂变，并对两个液滴的碰撞进行了数值研究。(C)2016 AIP出版有限责任公司。
We propose a model for the spontaneous motion of a droplet induced by inhomogeneity in interfacial tension. The model is derived from a variation of the Lagrangian of the system and we use a time-discretized Morse flow scheme to perform its numerical simulations. Our model can naturally simulate the dynamics of a single droplet, as well as that of multiple droplets, where the volume of each droplet is conserved. We reproduced the ballistic motion and fission of a droplet, and the collision of two droplets was also examined numerically. (C) 2016 AIP Publishing LLC.
