Dielectric droplet on a superhydrophobic substrate in an electric field

Research output: Chapter in Book/Report/Conference proceedingConference contributionResearchpeer-review

Abstract

A non-stationary electrohydrodynamic model of a dielectric droplet dynamics on solid substrate in surrounding gas is developed. The equations for electric field potential and fluid dynamics are solved together. Computer 3D simulations of liquid dielectric droplets on wettable and superhydrophobic surfaces are carried out. The dynamics of the pinned droplet is also simulated. The droplets tend to elongate in the direction of DC electric field. The droplet can jump over a superhydrophobic substrate after the electric field is applied.
