Abstract

The stability of a cylindrical jet of an incompressible, inviscid, dielectric liquid in a nonunifrom electric field was studied theoretically. The field is formed by a configuration of an electrified nozzle arranged vertically above a flat earthed electrode. Wave number and growth rate for the surface wave of the jet in the electric field were derived from the Lagrangian equation of motion for the jet. Perturbation analysis of the wave was used to formulate the equation. The effect of the electric field on the dynamic characteristics of the jet was investigated by numerical analysis, and it was confirmed that the wave number and maximum growth rate of the surface wave increased and the size of the drop formed decreased with applied voltage. The experimental drop diameter for the system of water jet in air in the nonuniform electric field agreed well with the calculated one. © 1989, The Society of Chemical Engineers, Japan.
