Multiscale simulation of soap bubbles rupture

Abstract eng:
The development of numerical method for soap bubble dynamics is of academic significance to understanding the underlying physics of the foams. In this study, we propose an efficient, robust and accuracy numerical method for simulating the dynamics of dry foams, including macroscopic evolution of membranes and its rupture on microscopic scale. The main feature of the method is its simplicity in implementation, both for the macroscopic interface advection and microscopic drainage. Regarding the interface advection we use a recently developed multi-region level-set method with high order discretization schemes while for drainage equation we use smooth particle hydrodynamics (SPH) to solve it. And the remesh method is employed to maintain the conservation during interface evolution and suddenly topology change. The results show the success in capturing the dynamics and rupture of soap cluster.
