Coalescence Between Adjacent Drops Lying on the Interface of Two Liquids
Abstract
This paper is aimed to the study and characterization of the coalescence of two adjacent drops lying on, or under (depending on the different densities), the macro-interface of two immiscible liquids. Experiments have been performed and coalescence times measured. A mechanistic model of coalescence is proposed. The comparison with experimental data is satisfactory.
