Simulation Interface between Marine Environment and Sea Platforms
Abstract
.We propose to develop a novel interface between the simulations of marine environment using the Wave-Ocean-Wind (WOW) codes and computational ship hydrodynamics (CSH) of sea platforms. The WOW codes are high-fidelity simulation tool for upper-ocean turbulence and currents, ocean waves, and wind. While they have great promise for simulating marine environment for sea platform applications, the WOW codes were originally developed for oceansciences applications without the consideration of the presence of sea platforms. In coupling WOW with CSH, we need to address challenges at the simulation interface, including the generation of spurious modes, loss of wave nonlinearity information, and loss of wave-coherent turbulence characteristics.In this project, we will develop novel numerical methods to address the above issues and reveal the fundamental mechanism of platform/environment interactions. We will first focus on the impact of sea platform wake flows on the realistic ocean mixed layer environment with turbulent mixing and stratification. The near-surface flow field (including the surface features), induced by sea platforms and subject to ocean environment impacts, will also be investigated. We will develop an interactive user interface for the marine environment simulation to receive inputs from the sea platform wakes. We will also use the WOW simulation to provide marine environment information to CSH simulation. The proposed project will be performed in close collaboration with naval researchers. Our work will focus on the computational methods and thefundamental fluid dynamics associated with idealized sea platform wakes. We will provide the simulation codes to naval collaborators for them to carry out application-oriented studies with realistic sea platforms. We aim to elucidate the fundamental mechanism of the interactions between marine environment and simple sea platform models, and will share our findings with naval collaborators.
