NETTUNO Numerical results - Multi-Fidelity simulation of single and tandem floating wind turbines

This dataset, collected as part of the NETTUNO research project, include numerical simulation results on a 1:75 scale model wind turbine. The primary focus of the endeavor was to analyze how platform motion in different directions affects the aerodynamics of the wind turbine rotor and the development of its wake. The dataset consists of two components:
•    Measurements of the aerodynamic forces and moments experienced by the rotor under various platform motion conditions.
•    Wind speed measurements collected at multiple downstream distances from the rotor, capturing the velocity profiles and turbulence characteristics within the turbine's wake.

As described more in detail in the companion deocuments, results consist of two "parts". The first consists of results obtained with setups that inclode on rotor only. The second contains results of simulations with two tandem rotors, where the first rotor undergoes armonic motions and the second is kept still. The contents are organized as follows: 

• P1_ALM: Results from simulations on one rotor using the Actuator Line Model
• P1_LLFVW: Results from simulation on one rotor using the Lifting Line Free Vortex Wake model 
• P2_LLFVW: Results from simulations on two tandem rotors using the Lifting Line Free Vortex Wake mode

The dataset is designed to serve as a comprehensive benchmark for researchers and engineers working on floating wind turbine aerodynamics, offering valuable insights for optimizing wind farm layouts and for developing simulation tools. More results may be added in the future as they are quality controlled and checked.
