Abstract:

The primary focus of this research is to use large-eddy simulation LES and large-wave simulation LWS to obtain improved physical understanding of wind-wave-ocean interactions, based on which we aim to develop effective models of wind input and whitecapping dissipation for phase-resolving, nonlinear wave-field simulation at large scales. Our ultimate goal is to establish a numerical capability for predicting deterministically large-scale nonlinear wave-field in real marine environments with the presence of significant wind and wave breaking effects. OBJECTIVES The scientific and technical objectives of this research are to develop advanced LES and LWS numerical capabilities for wind-wave-ocean interactions with physics-based subgrid-scale SGS models use high-performance LESLWS as a powerful research tool to obtain an improved understanding of the flow structure in the atmosphere-ocean wave boundary layer develop effective models for wind input and the associated whitecapping dissipation in a direct phase-resolving context, which can be readily incorporated into the deterministic numerical tool of the Simulation of Nonlinear Ocean Wave-field SNOW understand effects of multi-scale physics and environmental uncertainties upon wave deterministic propagation, and to effectively model these effects validate the direct modeling and simulation approach, and perform direct comparison with existing theories and field measurements.
