AB  - This study contributes to the field of wind engineering by evaluating the local peak pressure coefficients in a generic high-rise building cluster. Unlike previous studies that have focused on isolated buildings or buildings in tandem arrangements, this research considers the impact of four buildings when surrounding the principal one. Both experimental and numerical techniques are applied, demonstrating the capabilities of the LES method in predicting the local peak pressure. The obtained results offer new insights into the complex interplay between buildings and the wind
environment in high-rise building clusters, especially in the roof zone. The experiments reveal higher peak suction for the building in the group than the isolated at all wind angles. The minimum negative peak pressure coefficient of 5.8 is recorded at a 45° wind angle. Validation of the obtained numerical results shows the promising potential of the LES as a design tool in wind engineering, providing higher resolution of the quantities of interest.

AB  - Urbanisation brought an increasing prevalence of groups of high-rise buildings and raised new questions about their impact on local wind flow conditions and the wind energy harvesting potential. The focus of this study is two-fold. First, it gives insight into the interference effects around high-rise buildings based on the level of building exposure to the wind and the position of surrounding buildings. Second, it addresses wind energy resources above the roof in terms of the Wind Power Density (WPD), turbulence intensities and skew angle.

Three study cases are defined from two configurations: The isolated high-rise building and the group configuration of five identical buildings in two different arrangements. Two wind directions are included, 0°and 45°. Validated large-eddy simulations are used due to their superior simulation capabilities.

The strongest separation around the building is noted in the group configuration when the two upstream buildings produce the “channelling effect” and with other surrounding buildings compress the flow around the central one. Regarding wind energy harvesting, maximal value of 2.5 is recorded at 45°wind angle in the “cross” shape arrangement. Considering the different wind turbine types, vertical-axis wind turbines seem the most promising option for wind energy harvesting above the roof.

AB  - To understand the favourable locations for maximum yield of urban wind energy, understanding the flow pattern on the roof region of high-rise buildings is crucial. However, very few studies in the literature report on the wind energy resource using high-fidelity methods, which combined with the lack of wind tunnel investigations, explains the failure of urban wind energy as a viable contributor to the renewable energy mix. This work aims at proposing a strategy for the reliable evaluation of the wind energy resource by building on validated Large Eddy Simulation and performance maps based on the wind power density and the turbulence intensity above the roof of a prismatic 1:3 square building. Analyses include the effect of flat and decked roof shapes in two wind directions. Results around the facade reveal zones of accelerated flow close to separation edges, while above the roof, a higher potential is noticeable at 45◦, than at 0◦. Decking of the roof shows insensitivity to the change in wind direction. The tested methodology can be extended to other configurations to predict the wind energy potential as well as used to indicate the positioning of wind turbines in the built environment.

AB  - In this paper, pressure field over the roof of low-rise building model has been investigating using numerical simulations. The model is surrounded by four neighboring buildings of the same geometry as the principle one. The wind behavior around the building was simulated at wind angle of 45 degrees. Numerical calculations are performed using open-source code OpenFOAM. - Analysis solver for incompressible flow was applied using the Large Eddy Simulation (LES). The effect of different mesh types and inflow conditions are discussed. Two inlet definitions was implemented, one without prescribed turbulence, with the stream-wise velocity profile from the wind tunnel (WT), and another with the incoming flow turbulence synthetically generated using the divergence-free synthetic eddy method (DFSEM). Numerical results of pressure distributions statistics are analyzed and systematically compared to the referenced experimental data. The results show that there is a significant influence of the inlet definition on the mean and standard deviation of the pressure coefficient.

AB  - This paper presents the results of the application of the large eddy simulation (LES) numerical method with the aim of investigating static coefficients and nonstationary flutter derivatives for a common symmetric bridge deck section. The results are compared with those of the unsteady Reynolds-averaged Navier-Stokes (URANS) study. The results of the investigated numerical simulations are validated by force and pressure measurements from wind tunnel experiments. In addition to the commonly used representation of flutter derivatives based on the integrated forces, the paper uses cross-sectional representation by tracking the contributions of nonstationary coefficients around the bridge deck section. Besides providing a better insight into the physical mechanism, the cross-sectional representation seems to be a powerful tool for identifying deficiencies in visualizing the impact of flow separations on flutter derivatives.
