Abstract :
A complete self-consistent model has been developed for the motion of a conductive liquid surface on a capillary orifice, under an applied electric field. The model uses a quasi-one-dimensional hydrodynamic formulation and a two-dimensional axisymmetric boundary element solution for electric field. The model permits simulation of meniscus behavior with time-varying electric excitation or pressure. Results for resonance behavior and drop emission are presented, with experimental results for comparison
