Bursts of objects enclosed by thin films, such as balloons and cushions, are ubiquitous in our daily life while accurate models to simulate such phenomena have not been well studied yet. In this study, burst was defined as omnidirectional splashing outflow of content liquid accompanied with many droplets owing to break of the enclosing film, and a designated computational model was developed. The salient feature of the proposed model lies in its two-way coupling simulation, which takes into account the effects from the deformed thin films to the dynamics of the content liquid, and vice versa. Specifically, finite element analysis was used for stress computation with representation schemes to discretize the thin films and content liquid into triangular and tetrahedral elements, respectively. Since triangular and tetrahedral meshes provide the explicit boundary surfaces, they can strictly define the computation of collision and friction. After each of the time-steps, re-meshing is carried out for maintaining the accuracy of the simulation together with plausible fraction generation. Through the qualitative comparison with the high-speed camera video, it was empirically proven that the proposed model can accurately simulate bursts triggered by breaking thin films, which has not been realized by any other existing numerical schemes. |
