| 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. |
| Description: | Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE)hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization. |
