Supporting data belonging to publication: "On the wake re-energization of the X-Rotor vertical-axis wind turbine via the vortex-generator strategy"

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.

本数据集旨在支撑由Bensason、Sciacchitano与Ferreira合著的预印本论文《On the wake re-energization of the X-Rotor vertical-axis wind turbine via the vortex-generator strategy》的发表，该预印本目前已投稿至《Wind Energy Science》，DOI为10.5194/wes-2025-3。数据集包含采用粒子图像测速法（Particle Image Velocimetry, PIV），在代尔夫特理工大学（TU Delft）开放式射流风洞（Open-Jet Wind Tunnel Facility, OJF）设施中对直径0.6米的缩比X型转子垂直轴风力机（Vertical-axis wind turbine, VAWT）采集得到的尾流数据。尾流的横向截面测量范围覆盖至6倍转子直径处，采样间隔为1倍转子直径。研究人员为该X型转子的上叶片设置了三种固定桨距偏置工况，以此验证被称为“涡流发生器策略”的尾流恢复机制。本研究与配套数据集旨在为这款新型X型转子垂直轴风力机的数值模型后续研发与当前迭代开发工作，提供实验数据库支撑。
