Scattering study of a time-continuous breaking wave model generated in DualSPHysics

摘要

Breaking wave modeling is one of the most important difficulties in the simulation of sea scattering. To explore the scattering characteristics of a more realistic model, a time-continuous breaking wave model is developed in this paper, which is based on the open-sourced package of DualSPHysics. The electromagnetic (EM) scattering of several representative frames is calculated by the two-dimensional method of moments (MoM). In this paper, the characteristics of horizontal polarization (HH) and vertical polarization (VV) scattering under different sea conditions are elucidated. Sea spikes are pinpointed when incidence illuminating at large incidence angles. It turns out that when the wave surges, the scattering of both polarizations at large incident angles increase greatly, accompanied by significant changes in the scattering characteristics, resulting in remarkable sea spikes.
