Supporting data belonging to publication: "Experimental study of the impact of blade-tip mounted rotors on the X-Rotor vertical-axis wind turbine"

This dataset is intended to support the publication "Experimental study of the impact of blade-tip mounted rotors on the X-Rotor vertical-axis wind turbine" by Bensason, Sciacchitano, and Ferreira, published in the Journal of Physics: Conference series under DOI 10.1088/1742-6596/2767/7/072016. 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 1.5m, coined the primary rotor. The measurements focus on the bottom blade tips, which have blade-tip mounted rotors (approximately 10cm in diameter), coined secondary rotors. This study aims to evaluate the temporal and spatial evolution of the secondary rotor wake during the upwind passage of the primary rotor. Additionally, it provides an experimental demonstration of the working principle of the X-Rotor concept, coined the “aerodynamic gearbox”.

本数据集旨在支撑由Bensason、Sciacchitano与Ferreira发表于《Journal of Physics: Conference Series》、DOI编号为10.1088/1742-6596/2767/7/072016的论文《X型转子垂直轴风力涡轮机叶片尖端安装转子的影响实验研究（Experimental study of the impact of blade-tip mounted rotors on the X-Rotor vertical-axis wind turbine）》。该数据集包含在代尔夫特理工大学（TU Delft）开放射流风洞设施（Open-Jet Wind Tunnel Facility，OJF）中，针对缩比X型转子垂直轴风力涡轮机（vertical-axis wind turbine，VAWT）开展实验时，采用粒子图像测速技术（Particle Image Velocimetry，PIV）获取的尾迹数据；该缩比涡轮机直径为1.5米，被命名为主转子（primary rotor）。实验测量聚焦于安装了叶片尖端转子的底部叶片尖端，该叶片尖端转子直径约10厘米，被命名为次级转子（secondary rotors）。本研究旨在评估主转子迎风过境期间，次级转子尾迹的时空演化特性。此外，本数据集还提供了被称为“气动变速箱（aerodynamic gearbox）”的X型转子概念工作原理的实验验证。
