Abstract:

The goal is to identify the role of nonlinear wave interaction in the spatial coherence of ocean waves within the MOB Program of ONR. For this purpose, a numerical tool based on the Green-Naghdi model will be developed to simulate short-crested irregular waves in deep water. The objectives are to develop the higher-level Green-Naghdi model, to provide oceanographersocean engineers with a new numerical, nonlinear wave model, and to simulate efficiently the fully-nonlinear interaction in short-crested random ocean surface waves. Emphasis will be placed on the optimization between accuracy and computational effort by adjusting the Level of the model.
