Radial deformation and disintegration of an electrified liquid jet

Abstract
Droplets stretched by electric stresses emit jets from their pointed tips. We observed in the experiment a new tip-streaming phenomenon by applying a radial electric field to a liquid jet. Droplets in the jet are stretched in the radial direction and develop into a disk-like shape. The growth of non-axisymmetric harmonics leads to the formation of tens of Taylor cones evenly distributed at the equator of a droplet. At the tip of each cone, a tiny secondary jet is emitted, which breaks up into progeny droplets orders of magnitude smaller than the parent ones. This tip-streaming pattern may provide a new spraying route to the generation of micro- and nanosized droplets.
