Description The interaction and coalescence of a freely suspended drop pair, aligned in a uniform DC electric field is investigated using experiments, analytical theory, and numerical calculations (boundary element method (BEM)). The systems considered are a pair of perfect conductor drops in a perfect dielectric fluid and a pair of leaky dielectric drops suspended in another leaky dielectric fluid. The applied electric field induces a dipole in the drops that form a pair, leading to their approach and subsequent merger. The study focuses on the drop approach and the film drainage stages of drop-drop electrocoalescence. The shapes and motion predicted using BEM are in good agreement with the experimental results and analytical theory. (C) 2015 AIP Publishing LLC.
