Abstract

High fidelity simulations of the DeltaWind platform are performed using openFoam CFD (Computational Fluid Dynamics) simulations. The simulated cases have been configured under the openFOAM environment and using the utility cenerFOAM that helps the user to mesh the geometry, configure the cases, run simulations and post process the results. The CFD analysis of the platform will evaluate movements, forces and moments of the platform as well as magnitudes that cannot be obtained from potential analysis such as wave run up and pressures in the structure for design purposes. The challenge of floating wind is the reduction of LCOE and it will only be achieved when the floater designs are fully optimized and the flow phenomena fully understood and characterized. With CFD simulations, detailed information of pressures and wave run up in the floating structures will be obtained and integrated in the certification process of floating offshore wind turbines (FOWT). In addition, CFD can simulate extreme conditions cases that could not be studied with potential since they are out of the range of application of such codes. These extreme conditions cases appear specially in the single point mooring platforms, where the orientation maneuvers combined with the wind turbine dynamics lead to load cases that require accurate studies. High fidelity simulations will support the industry in the coming years where up scaling of prototypes is envisaged to reach 15 MW FOWTs in 2025.
