Recent advances in understanding the dynamic characterization of floating offshore wind turbines

The main purpose of the present paper is to cover the lack of a reference point in the literature providing a comprehensive review of the state of the art, recent developments, and future challenges relatives to analytical, experimental, and numerical approaches tailored for the field of dynamic characterization of floating offshore wind turbines, with a focus on aerodynamics, hydrodynamics, and anchoring systems. The Real Time Hybrid Approach makes it possible to overcome some of the problem...

On the effects of wind and operating conditions on mooring line tensions for floating offshore wind turbine

The present work addresses a significant topic in the current understanding of the structural dynamic behavior of mooring lines for floating offshore wind turbines (FOWT) in operating condition and aims to contribute to the ongoing efforts to enhance the performance and reliability of floating offshore wind energy systems. The present paper investigates the impact of operating conditions on mooring line tension for FOWT. A numerical model of a spar-type FOWT developed in Orcaflex, validated w...

Direct Scaling of Measure on Vortex Shedding through a Flapping Flag Device in the Open Channel around a Cylinder at Re ∼ 10^3: Taylor’s Law Approach

The problem of vortex shedding, which occurs when an obstacle is placed in a regular flow, is governed by Reynolds and Strouhal numbers, known by dimensional analysis. The present work aims to propose a thin films-based device, consisting of an elastic piezoelectric flapping flag clamped at one end, in order to determine the frequency of vortex shedding downstream an obstacle for a flow field at Reynolds number Re∼103 in the open channel. For these values, Strouhal number obtained in such way...
