On Theoretical Prerequisites for the Classification of Liquid Electrodispersion Modes

A purely theoretical approach has been proposed for constructing the classification of the observed modes of liquid electrodispersion from the edge of a capillary, through which the liquid is supplied into a discharge system, in contrast to the phenomenological classifications suggested previously. The classification is proposed to be realized in accordance with the physicochemical properties of liquids, as well as the degree of symmetry of azimuthal surface waves of a jet ejected from a meniscus and the regularities of droplet detachment directly from the meniscus. It has been shown that, when a low-viscosity and rather high-conductivity liquid is dispersed, the meniscus emits strongly charged droplets, which are unstable with respect to their own charges and disintegrate into smaller droplets. Low-conductivity liquids emit either weakly charged droplets stable with respect to their own charges or charged liquid jets, which disintegrate into stable droplets.

Automated summary

This article proposes a purely theoretical approach for the classification of liquid electrodispersion modes based on the physicochemical properties of liquids, as well as the symmetry of surface waves and droplet detachment from the meniscus. Experimental results show that low-viscosity, high-conductivity liquids emit strongly charged droplets that disintegrate, while low-conductivity liquids emit either weakly charged droplets or stable charged liquid jets that disintegrate into stable droplets.
