On the Charge Instability and the Metastable Equilibrium State of a Conducting Droplet during Liquid Electrospraying

It is known that highly charged droplets formed in the course of electrospraying disintegrate into a number of smaller droplets. The criteria for the instability and disintegration of conducting liquid droplets in the course of electrospraying have been considered in this article. Some forms of the perturbation of a spherical liquid droplet have been shown for the case when the Rayleigh stability criterion is exceeded. The analysis of the development of charge instability has shown that a quasi-stable state may exist during the disintegration of a liquid droplet in the region of instability according to the Rayleigh criterion.
