| Zusammenfassung |
| In this study, we performed the three-dimensional numerical simulation and analysis for
solving the dynamic loads from waves and currents on the offshore wind turbines.
Scenarios focused on the extreme weather conditions. During the typhoon event, the
wind-driven storm waves and currents have to be considered while solving the
dynamic load on the structures. The Splash3D model was adopted to perform the
simulation of the interaction between breaking waves and structures. The core of
the Splash3D model is the Truchas model which was developed by Los Alamos
National Laboratory (LANL) and featured as high accuracy. Splash3D is capable of
solving the dynamic process for the interaction between the structure and fluids with
complex breaking free-surface. This model is also able to simulate the local scour
under the violent flow condition. In order to adequately simulate the waves under
monsoon or typhoon, we developed a new wave generation module based on the
dispersion relationship. This wave-maker module was used to generate regular waves,
irregular waves, and breaking waves under the extreme weather condition. The
module was used to simulate the synthetic effect under the effects of waves and
currents for obtaining the force distribution on the foundation of the offshore wind
turbine.
