Hydrodynamic Modeling for Stationary Breaking Waves

Abstract

In this study, approaches for calculating the hydrodynamics of breaking waves were examined and the impact of hydrodynamic model errors on the prediction of radar backscatter was assessed. Reynolds-averaged Navier-Stokes (RANS) computations of stationary hydrofoil-generated breaking waves were carried out, including the modeling of the breaking region. These results were compared to experimental data. A subset of these results was used as input to the Veridian scattering model (VSM) and the results were also compared to available data. The results were then used define the research needs in this area.
