Breakup of electrified drops
ORAL
Abstract
A drop that is subjected to an electric field is a situation of common occurrence in nature and technology. Well known examples of drops subjected to electric fields include raindrops in thunderstorms and aqueous drops dispersed in an organic solvent in electrically-driven solvent extraction. A field of sufficiently high strength destabilizes such drops. The dynamics and disintegration of the drops are investigated here using a combination of simulation and experiment. The disintegration of the parent drop into daughter drops is analyzed and shown to accord well with experimental measurements. The implication of the findings to other fields, e.g. soft lithography, is also discussed.
