论文摘要
液滴合并是化学，物理和生物学系统中普遍存在的现象。液体对象合并的过程在粘贴过程中在实验和理论上在不同的几何形状上进行了研究。我们介绍了一个唯一系统，该系统允许对合并过程的准二维描述，在自由悬挂的近晶液晶膜中千分米尺寸的平滴。我们发现连接液滴的桥在Coalesencence的初始阶段在其高度和侧面宽度方面及时生长。我们还验证了合并第一阶段的桥梁的自然动力学。我们比较了基于薄板方程的模型。
Coalescence of droplets is an ubiquitous phenomenon in chemical, physical and biolog-ical systems. The process of merging of liquid objects has been studied during the pastyears experimentally and theoretically in different geometries. We introduce a uniquesystem that allows a quasi two-dimensional description of the coalescence process,micrometer-sized flat droplets in freely suspended smectic liquid-crystal films. We findthat the bridge connecting the droplets grows linearly in time during the initial stage ofcoalescence, both with respect to its height and lateral width. We also verify self-similardynamics of the bridge during the first stage of coalescence. We compare our resultswith a model based on the thin sheet equations.
