Transient analysis of the slamming wave load on an offshore wind turbine foundation generated by different types of breaking waves

In this study, a computational fluid dynamics model was employed to simulate the impact of breaking wave on foundation an offshore wind turbine. The accuracy numerical simulation validated in comparison with published experimental results for Large Wave Channel (GWK) at Hannover, Germany. To understand influence wave-breaking location monopile support structure, series shoaling waves different spilling and plunging types were considered terms surf-similarity parameter ([Formula: see text]) relative distance text]). After processing total load empirical mode decomposition method low-pass filter, instantaneous nature slamming generated by obtained. Subsequently, exponential-type refined dynamic established consider characteristics filtered load. [Formula: text] found be dominant factors run-up phenomena, characteristics, wave-dependent parameters. demonstrated that these two coefficients can applied determine loads.
