Abstract

A numerical scheme based on the lattice Boltzmann method, which can simulate the electrowetting of an electrolyte droplet and flow is proposed. The accuracy and robustness of this model are demonstrated by numerically simulating a droplet on a flat surface, on which the cosine of contact angle shows parabolic increase consistent with the Lippmann-Young equation. This scheme is expected to the application in the study of the mechanism of electrowetting on dielectric and electrowetting fluid in complex geometry.
