Droplet impact on superhydrophobic surface under theinfluence of an electric field

comprehensive understanding of the dynamics of droplets impacting on solid surfaces is required in a large number of technological and industrial cases. Recently, superhydrophobic surface with its particular characteristics has attracted increasing attention among the scholars andindustrialists. Besides the thirst for knowledge, researchers have been driven by the many possible applications of drop impinging superhydrophobic materials under the influence of electric field in several fields, such as electrostatic separation of water-in-oil dispersions for the crude oil industry. Therefore, this paper presents the dynamic behavior of a water droplet impinging on superhydrophobic substratessurrounded in oil medium. After validating the numerical method, the effects of variations in impact velocity and electric field strength are investigated to clarify the underlying physics of this phenomenon
