Numerical method to impose free-surface boundary conditions for local free-surface flows

Abstract
This paper proposes a simple numerical technique to impose free-surface boundary conditions (FSBC) for free-surface flows governed by surface-vortex interactions. Accuracy and efficiency of this technique are examined through the analytical and experimental comparisons. The deformations of a free-surface and evolution of vortices at droplet impacts onto a water pool is reasonably reproduced by properly prescribing FSBC via the proposing method. Typical vortex rings are found to be initiated at the contacts between the droplet and receiving water-surface and to threedimensionally develop through a splashing process for interacting with a free-surface. The dependencies of flow field on an impact angle of the droplet are also discussed in this study.
