Study of Ocean Wave Statistical Properties using Nonlinear, Directional, Phased-Resolved Ocean Wave-Field Simulations

摘要

In the present work, we study the statistics of wavefields obtained from non-linear phase-resolved simulations. The numerical model used to generate the waves models wave-wave interactions based on the fully non-Linear Zakharov equations. We vary the simulated wavefiled's input spectral properties: direction spreading function, Phillips parameter and peak shape parameter. We then investigate the relationships between a wavefild's input spectral properties and its output physical properties via statistical analysis. We investigate surface elevation distribution, wave definition methods in a nonlinear wavefield with a two-dimensional wavenumber, defined waves' distributios, and the occureence and spacein of large wave events.
