Three-dimensional modeling of dynamics of liquid dielectric droplets on a wettable surface in the electric field

Research output: Contribution to journalConference articlepeer-review

Abstract

Three-dimensional non-stationary modeling of liquid dielectric droplets on a wettable surface in an electric field is performed. The distribution of the electric field is calculated by solving the equation for the electric field potential. The lattice Boltzmann method is employed to describe the hydrodynamic processes with gravitational, electrostatic, and capillary forces. A hemispherical droplet is placed on the surface of the lower electrode. Two variants of the droplet behaviour are observed. The droplet can acquire its equilibrium shape after several oscillations or elongate unlimitedly up to its destruction.
