摘要：
In this paper, a numerical method is used to study the phenomenon of electrowetting to control droplets impacting a hydrophobic surface. The contact angle is changed by applying voltage to control the movement of the impacting droplets. Use COMSOL Multiphysics 5.4 to build models and conduct numerical studies. When no voltage is applied, the droplets will partially bounce upon impact. When an alternating current signal of a certain frequency and amplitude is applied, the partially bounced droplets will be adsorbed on the surface without rebounding. In this paper, the two-dimensional modeling of the alternating current electrowetting of the open structure is carried out to explore the influence of the amplitude and frequency of the alternating current on the droplet impact suppression effect. © 2021, Science Press.
