Numerical study of the response of floating wind turbines via computational fluid dynamics
Abstract
Offshore wind turbines are rapidly increasing in size to capture stronger winds further offshore. However, as water depths increase, the designs of bottom fixed offshore wind turbines are no longer suitable, thus needing floating wind turbines design for depths greater than 50 m. The significant dimensions of these sub-structures may lead to significant hydroelastic phenomena, which can also affect the elastic response of the tower, and so cannot be neglected. Reliable design of the floating substructures is necessary to avoid exciting certain eigen frequencies at low and high frequencies, with repercussions on the operation and fatigue life of the turbine. From a hydrodynamic point of view, a number of authors has carried out the study of seakeeping using high-fidelity CFD codes, then by characterising the fluid-dynamic constraints by solving the Navier Stokes equations using the finite volume method. An extension of these numerical models would also allow the flexibility of the structure to be taken into account. The aim of the present work is to reproduce the experimental results obtained by (LEROY et al., 2022) on a flexible SPAR platform model at the hydrodynamic and ocean engineering basin of Ecole Centrale de Nantes. The use of a high-fidelity numerical model (CFD) will be examined in order to study the floater dynamic response observed during the experimental campaign at the wave basin.
