导致聚结的导电水分散在绝缘液体中的小液滴的基本过程中检查的情况下，两个同轴的圆柱形电极之间流动的乳液和受到电场。首先回顾了给出两液滴之间的相互作用力的公式和多分散乳液的演化方程。推导了只保留场诱导液滴间相互作用时的聚结速率表达式，并估算了特征聚结时间。最后提出剪切速率在使液滴接触中起主要作用。
The basic processes leading to coalescence of small droplets of conducting water dispersed in an insulating liquid are examined in the case of an emulsion flowing between two coaxial cylindrical electrodes and subjected to an electric field. The formula giving the interaction force between two droplets and the equation governing the evolution of a polydispersed emulsion are first recalled. Expressions are derived for the coalescence rate when retaining only the field induced interaction between droplets and the characteristic coalescence time is estimated. Finally it is proposed that the shear rate plays the major role in bringing the droplets into contact.
