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

本数据集旨在支撑Bensason、Sciacchitano、Giri Ajay与Ferreira发表的论文《带变桨叶片X型转子垂直轴风力机近尾流变形研究》（DOI: 10.22541/au.170664317.75532826/v1）的相关研究结论。本数据集包含在代尔夫特理工大学（TU Delft）开式射流风洞（Open-Jet Wind Tunnel, OJF）设施中，采用粒子图像测速法（Particle Image Velocimetry, PIV）测得的缩比X型转子垂直轴风力机（Vertical-Axis Wind Turbine, VAWT）尾流数据。研究通过对叶片施加固定桨距偏移，验证了X型转子概念的尾流恢复机制。此外，本数据集还提供了数值模拟数据，用以阐明该尾流恢复策略对叶片载荷的影响。本研究与数据集旨在为该新型X型转子垂直轴风力机的数值模型后续研发与迭代提供实验数据库支撑，同时验证了采用固定桨距偏移的垂直轴风力机尾流恢复策略。
