Wind tunnel experimental data for flow characteristics above the roof of high-rise buildings in group arrangement for wind energy harvesting

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 flat roof top of a high-rise building with a square cross section and height to width ratio of 1:3 surrounded by four buildings of the same geometry. The main purpose is to be used for estimation of urban wind energy potential; and in addition 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°.本数据集呈现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。实验场景为一座截面呈正方形、高宽比为1:3的高层建筑，该建筑四周环绕四座几何参数完全相同的周边建筑，研究测量了该建筑平坦屋顶上方的流场。本研究的核心用途为评估城市风能潜力，此外还可用于未来计算流体动力学模拟的验证工作。除了主要在屋顶上方三处测点开展的流速场测量外，本次实验还同步采集了屋顶表面的压力数据。实验针对0°、15°、30°及45°四种不同风向角，完成了屋顶上方流场的测量。
