A numerical model for the simulation of fully-coupled fluid-structure interaction is developed in this study. In modeling the fluid, the Reynolds Averaged Navier-Stokes equations are solved for an incompressible viscous fluid field and a k-&egr; model is employed for turbulence computations. Hydrodynamic forces obtained by the integration of the fluid pressure along the structural boundaries are applied as external excitation forces to the structural system and the dynamic response of the structural system is computed based on dynamic equilibrium. To determine the nonlinear dynamic response of the structure in the flow field, iterative procedures are developed. The numerical model is verified and validated through comparisons with several different types of experiments.

520 $a A numerical model for the simulation of fully-coupled fluid-structure interaction is developed in this study. In modeling the fluid, the Reynolds Averaged Navier-Stokes equations are solved for an incompressible viscous fluid field and a k-&egr; model is employed for turbulence computations. Hydrodynamic forces obtained by the integration of the fluid pressure along the structural boundaries are applied as external excitation forces to the structural system and the dynamic response of the structural system is computed based on dynamic equilibrium. To determine the nonlinear dynamic response of the structure in the flow field, iterative procedures are developed. The numerical model is verified and validated through comparisons with several different types of experiments.
520 $a The numerical model is then applied to examine the runup and rundown of the submarine landslide generated waves with various configurations. The functional relationships between the maximum runup/rundown and the geometric and material properties of landslides are obtained.
520 $a The numerical model is also applied to predict the experimental moored response of a structure subjected to periodic waves. The linear and nonlinear waves, as well as the structural response, are modeled accurately. The dynamic response of the moored structure, which is modeled with nonlinear restoring forces, shows the characteristic behaviors such as sub-harmonic/super-harmonic responses. General application procedures for the fluid-structure interaction model are presented. The subaerial and aerial drop of a rigid body and the influence of impact on the fluid body are examined.
