Cone-Jet Analytical Extension of Taylor’s Electrostatic Solution and the Asymptotic Universal Scaling Laws in Electrospraying

Abstract

An analytical cone-jet solution for the electrohydrodynamic atomization of liquids has been foundfor an asymptotic model assuming an infinitely long and thin emitted jet. Universal expressionsfor the emitted electric current, jet shape, charge distribution, surface charge, and other essentialelectrohydrodynamic quantities are obtained as functions of the liquid properties and the emitted liquidflow rate. The agreement with published experiments is good.
