Dynamic Fluid responses under Overfow due to Partial Collapse of Water Column

Abstract

Three-dimensional evolution of local fluid flow and surface shape under partial water column collapse, which models overflow due to local failure of a vertical wall, is characterized in computational experiments using three-dimensional large eddy simulation. Free-surface responses highly depends on the collapse level and ambient water layer depth via mechanical interactions between the surface and vortices. The fluid stresses due to the overflow are parameterized by a simple hydraulic model proposed in this study.
