This dataset is intended to support the publication "On the wake re-energization of the X-Rotor vertical-axis wind turbine via the vortex-generator strategy" by Bensason, Sciacchitano, and Ferreira, now in preprint with Wind Energy Science at 10.5194/wes-2025-3. The dataset includes wake data obtained using Particle Image Velocimetry (PIV) in the open-jet wind tunnel facility of the TU Delft (OJF) for a scaled X-Rotor vertical-axis wind turbine (VAWT) with a diameter of 0.6m. The wake at cross-stream planes is measured up to a distance of 6 diameters at increments of 1 diameter. Three fixed-pitch offsets are applied to the upper blades of the X-Rotor to demonstrate a wake recovery mechanism known as the "vortex-generator" method. This research and dataset aim to provide an experimental database for the future and ongoing development of numerical models for this novel X-Rotor VAWT.
