Abstract

Formation of single charged drops from a laminar liquid jet issuing from an electrified nozzle in a nonuniform electric field was studied for the systems of xyleneair and water-air, -cyclohexane, -hexane and -silicone oil. The field was formed by a configuration of an electrified nozzle arranged vertically above a flat earthed electrode. The jet length, jet radius and drop diameter decrease with applied voltage. It was shown that the experimental drop diameters agree well (within ± 10%) with those calculated by using wave number and growth rate for interfacial wave for all systems. It was clarified experimentally that a whipping action of the jet is caused by applying voltage when the electric pressure acting on the jet is greater than the interfacial one acting on the jet. © 1989, The Society of Chemical Engineers, Japan.
