Wind tunnel measurements of loads and wakes in tandem floating wind turbines under harmonic surge motion

This dataset contains wind tunnel measurements of aerodynamic loads and wake velocity fields for tandem floating wind turbines subjected to prescribed harmonic surge motion. The experiments were conducted on two 1:150 scale models of the DTU 10 MW wind turbine, aligned with the incoming flow and spaced 5.75D apart. The test matrix includes variation of motion frequency and phase difference between the turbine motions. The dataset provides time-resolved aerodynamic rotor load measurements (forces and moments) together with hot-wire measurements of the streamwise velocity in the wake at multiple downstream locations. Tests were performed under uniform low-turbulence inflow conditions (approximately 2%), for different motion frequencies and relative phase offsets, enabling the investigation of wake modulation, turbine–turbine interaction, and wake–motion synchronization effects. The data support the analysis presented in the associated publication and are intended for validation of numerical models and further studies on floating wind farm aerodynamics.
