二维泡沫中的聚结:一个纯统计过程
Coalescence in two-dimensional foams: a purely statistical process
摘要:
虽然聚结最终是泡沫中最剧烈的不稳定过程,但其基本过程仍不清楚。为了更好地理解它们,我们跟踪在受控的毛细管压力下二维泡沫中的单个聚结事件。我们得到的统计信息揭示了不同的参数,以前提出来解释合并的影响。我们的主要结论是,合并的概率是简单地成正比的薄膜分离两个气泡的面积,这表明合并主要是随机的。
英文摘要:
While coalescence is ultimately the most drastic destabilization process in foams, its underlying processes are still unclear. To better understand them, we track individual coalescence events in two-dimensional foams at controlled capillary pressure. We obtain statistical information revealing the influence of the different parameters which have been previously proposed to explain coalescence. Our main conclusion is that coalescence probability is simply proportional to the area of the thin film separating two bubbles, suggesting that coalescence is mostly stochastic.
