Supporting data belonging to publication: "A study of the near wake deformation of the X-Rotor vertical-axis wind turbine with pitched blades"

This dataset is intended to support the findings of the publication "A study of the near wake deformation of the X-Rotor vertical-axis wind turbine with pitched blades" by Bensason, Sciacchitano, and Giri Ajay, and Ferreira (DOI: 10.22541/au.170664317.75532826/v1). 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). The near wake of the rotor is measured with fixed-pitch offsets applied to the blade to demonstrate a wake recovery mechanism for the X-Rotor concept. Furthermore, numerical simulation data is provided to highlight the impact of this wake recovery strategy on the blade level loading. 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. Furthermore, it demonstrates the wake

recovery strategy for VAWTs, which uses fixed blade pitch offsets.
