Wind Tunnel Experimental Data for Flow Characteristics above the Roof of Isolated High-rise Building for Wind Energy Harvesting Considering Two Shapes of the Roof, Flat Roof and Deck Roof

This data presents an experimental investigation carried out in a Boundary Layer Wind Tunnel located at Ruhr University Bochum, Germany. The flow field is measured above the rooftop of a high-rise building with a square cross-section considering two different roof shapes, flat roof and deck roof. The height-to-width ratio of the building was 1:3. The main purpose is to be used for estimation of urban wind energy potential, and besides for future validation of computational fluid dynamic simulations. Besides velocity field, measured at mainly three positions above the roof, the roof surface pressure was also measured. The flow above the roof was measured for different wind angles: 0°, 15°, 30°, and 45°.本数据集收录了一项在德国波鸿鲁尔大学（Ruhr University Bochum）边界层风洞（Boundary Layer Wind Tunnel）中开展的实验研究成果。研究针对方形截面高层建筑的屋顶上方流场开展测量，试验涵盖两种屋顶构型：平顶屋顶（flat roof）与挑檐屋顶（deck roof），该建筑的高宽比为1:3。本数据集的核心应用场景包括：一是用于城市风能潜力评估，二是为后续计算流体动力学（computational fluid dynamic, CFD）模拟的验证提供基准数据。除了主要在屋顶上方三个测点开展的速度场测量外，本次试验同时采集了屋顶表面的风压数据。试验针对0°、15°、30°及45°四种不同风向角，完成了屋顶上方流场的相关测量工作。
