In this paper, the rupturing of a bubble under an external oscillatory excitation in a cylindrical container is studied using an in-house developed numerical model. The container is occupied by an incompressible liquid. The Volume-Of-Fluid (VOF) method is used to track the liquid-gas interface. The two-step projection method is used to discretize the continuity and momentum equations. The main purpose of this study is the characterization of bubble rupturing phenomenon. The frequency and amplitude effects on the rupturing threshold are evaluated. Furthermore, the effect of the presence and the absence of gravity on this threshold are studied. Finally, a correlation consisting Bond number, Reynolds number and non-dimensional amplitude is provided to capture the bubble-rupturing region. The effect of container walls on the bubble rupturing is also considered. The comparison between the results of numerical simulations and those of the available experiments reveals a good agreement.
