Abstract
A perturbation method is used to study the stability of the interface between a cylinder formed by the flow of an inviscid liquid dielectric and air in the presence of an external electrostatic field produced by coaxial electrodes. The field is perpendicular to the interface. The outer electrode is at a potential V0 and the inner electrode is grounded. An equation is found for the neutral-equilibrium curve, and the threshhold values of V0, i.e., those at which the surface becomes unstable, are calculated for the case in which the outer radius of the stream is twice the inner radius.
