Numerical Study of Breaking Waves.

摘要

The focus of the present work is on the numerical simulation of steady flows with spilling breaking waves. In particular, the breaker is modeled through a hydrostatic pressure and a shear stress exerted on the free-surface. Many elements of the exposed model are derived by Cointe and Tulin's theory of steady breaker. The model has been implemented in a RANSE code in a simple but effective way through a modification in the free-surface boundary conditions. At present, the resulting code is valid for two-dimensional flows, and has been accordingly tested against the experimental data obtained by Duncan for the flow generated by a hydrofoil towed under the free-surface at different velocities and depths.
