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°.
