最近，在两个平行板之间的受限几何中（即在Hele-Shaw槽中），研究了液滴与液浴的结合。发现动力学表现出从最初的三维到另一个最终的准二维的转换。在这项研究中，我们从三个不同的角度提出了原始的和简单的缩放论点来重现预测的理论，以阐明最近发现背后的基本物理学。
Recently, coalescence of a drop to a liquid bath has been studied in a confined geometry between two parallel plates (i.e., in a Hele-Shaw cell). The dynamics was found to exhibit a turnover from an initial three-dimensional one to another final quasi two-dimensional one. In this study, we develop original and simple scaling arguments to reproduce the predicted theory from three different viewpoints to elucidate the essential physics behind the recent findings.
