The behavior of drops in the emulsion is significant in transport phenomena and the oil and the petrochemical industry. In this study, the behavior of drops that are close to each other was investigated. These drops were studied at two viscosity ratios (0.5 and 0.9, which are the viscosity ratio of drops to fluid) and six capillary numbers (0.05, 0.11, 0.17, 0.42, 0.28, and 0.36). The results demonstrate the effect of drops on each other at a range of volume fractions. Also, at capillary numbers of 0.42, 0.82, and 0.36, there were volume fractions at which drops stuck to each other and broke after combining. In contrast, the single drop at these new capillary numbers after merging was not broken. At the capillary number of 0.84, and volume fraction of 0.001495, the drops did not stick to each other, but they were broken under the influence of each other. For each capillary number, a specified volume fraction was achieved, at which the drops behave as a single drop. Therefore, in each capillary number, a volume fraction can be found so that in volume fractions less than that, drops behave individually and do not interact with each other.

乳液中液滴的行为在运输现象以及石油和石化工业中具有重要意义。在这项研究中，研究了彼此靠近的液滴的行为。这些液滴以两种粘度比（0.5 和 0.9，即液滴与液体的粘度比）和六个毛细管数（0.05、0.11、0.17、0.42、0.28 和 0.36）进行研究。结果证明了在一定体积分数范围内液滴之间的相互影响。另外，在毛细管数为0.42、0.82、0.36的情况下，存在液滴彼此粘连、合并后破裂的体积分数。相比之下，合并后这些新毛细管数的单次下降并未被打破。当毛细管数为0.84、体积分数为0.001495时，液滴彼此不粘连，但在彼此的影响下破裂。对于每个毛细管数，都达到了指定的体积分数，在该体积分数下，液滴表现为单个液滴。因此，在每个毛细管数中，可以找到一个体积分数，使得在小于该体积分数的情况下，液滴各自表现并且不会彼此相互作用。
