“…In the frame of the numerical study, the three-dimensional steady RANS simulations have been carried out using a commercial CFD code, FLUENT v.17, with the realizable version of k-epsilon turbulence model. According to the literature ( [3][4][5]12]) this model is widely used for analysis of flows for different configurations of buildings.…”

“…The studies of the wind environment around buildings are generally performed as wind tunnel experiments since it is the most well-established way to simulate a natural wind. In the past decades, numerous studies showed that the prediction of flow field in the surroundings of high-rise buildings in urban environments is very effective by the use of Computational Fluid Dynamics (CFD) [1][2][3][4]. Most of the studies have dealt with complicated, real configurations so it is uncertain whether the prediction of CFD is accurate.…”

Abstract. The problem of flow field in the urban boundary-layer (UBL) in aspects of wind comfort around buildings and pollutant dispersion has grown in importance since human activity has become so intense that it started to have considerable impact on environment. The issue of wind comfort in urban areas is the result of complex interactions of many flow phenomena and for a long time it arouses a great interest of the research centres. The aim of article is to study urban atmospheric flow at the local scale, which allows for both a detailed reproduction of the flow phenomena and the development of wind comfort criteria. The proposed methodology involves the use of PIV wind tunnel experiments as well as numerical simulations (Computational Fluid Dynamics, CFD) in order to enhance understanding of the flow phenomena at this particular scale in urban environments. The analysis has been performed for the 3D case of two surface-mounted buildings arranged in tandem, which were placed with one face normal to the oncoming flow. The local characteristics of flow were obtained by the use of commercial CFD code (ANSYS Fluent). The validation was carried out with reference to the PIV results.

Summary Twin high‐rise buildings, that is, two closely located tall buildings with identical or similar geometrical features, are inevitably under wind‐induced interference effects. Most previous studies employed rectangular or circular prisms as twin tall buildings to investigate the interference effects. Therefore, these findings need further verification and modification for twin high‐rise buildings with more complex exterior geometries. This study uses wind tunnel pressure measurement tests to investigate the interference effects on typical twin super‐tall buildings with a tapered shape and recessed corners. Structural overall overturning moments and surface wind pressures applied on the twin skyscrapers are analyzed and discussed in detail. The interference effects on the twin skyscrapers are further compared with those on paired square prisms with the same height and footprint breadth. The results show that the interference effects on the twin tapered super‐tall buildings differ considerably from those on the square prisms, and the critical building configurations that need cautious treatment in the designs of twin skyscrapers are specified.
