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°.

本数据集呈现了在德国波鸿鲁尔大学边界层风洞中进行的实验性研究。研究测量了位于一栋具有正方形横截面、高度与宽度比为1:3的高层建筑平坦屋顶上方的流场，该建筑周围环绕着四栋几何形状相同的建筑。主要目的在于用于估算城市风能潜力；此外，还用于未来对计算流体动力学模拟的验证。除了在屋顶上方主要三个位置测量的速度场外，屋顶表面的压力也被测量。对屋顶上方的流动进行了不同风向角（0°、15°、30°和45°）的测量。
