Title: SBW

Abstract:
We address the critical need for high-resolution data sets to develop
closure models for steep/violent ship waves. To this end we develop
high-resolution large-eddy/large-wave simulation (LES) capabilities
that include both the water and air phases using the conservative
volume-of-fluid (CVOF) formulation.  We apply these tools to study
canonical problems of ship breaking waves (SBW), specifically the flow
behind an idealized transom stern. We obtain two-dimensional and
three-dimensional simulation results covering a range of Froude
numbers and flow regimes.  The mean and fluctuating values for
water/bubble density and flow parameters under different averaging
approaches are quantified, and their modeling implications
investigated.
