Modeling of Complex Coupled Fluid-Structure Interaction Systems in Arbitrary Water Depth

The long-term goal of this research is to develop a robust multi-physics, multi-scale computational framework for the prediction and analysis of highly nonlinear dynamic behavior of naval systems in the marine environment of arbitrary water depth. The predictive capability will be sufficiently general for a variety of naval systems with a wide range of structural and mechanical complexities operating under deterministic and stochastic environmental conditions from deep water to the surf zone. Physicsspecific numerical models included in the framework will take into account nonlinear effects of free surface, turbulence, wave breaking, fluid-structure and structure-structure impacts, large geometry, material, and structural interaction with seabed sediments.
