The effects of small vibrations on the surface oscillation of liquid bridges, especially the resonance behavior, were investigated numerically. The three-dimensional direct numerical simulation was based on the level set method to predict the surface oscillation of isothermal liquid bridges held vertically between solid disks. By subjecting the liquid bridges to various horizontal vibrations, the surface resonance frequencies were clearly determined numerically. The numerical resonance frequencies compared well with the analytical model predictions in another work. The effect of small vibrations on the induced flow structure inside the liquid bridge is also discussed.
