AB  - Computational fluid dynamics (CFD) represents an attractive tool for estimating wind pressures and wind loads on high-rise buildings. The CFD analyses can be conducted either by low-fidelity simulations (RANS) or by high-fidelity ones (LES). The low-fidelity model can efficiently estimate wind pressures over a large range of wind directions, but it generally lacks accuracy. On the other hand, the high-fidelity model generally exhibits satisfactory accuracy, yet, the high computational cost can limit the number of approaching wind angles that can be considered. In order to take advantage of the main benefits of these two CFD approaches, a multi-fidelity machine learning framework is investigated that aims to ensure the simulation accuracy while maintaining the computational efficiency. The study shows that the accurate prediction of distributions of mean and rms pressure over a high-rise building for the entire wind rose can be obtained by utilizing only 3 LES-related wind directions. The artificial neural network is shown to perform best among considered machine learning models. Moreover, hyperparameter optimization significantly improves the model predictions, increasing the 𝑅��2 value in the case of rms pressure by 60%. Dominant and ineffective features are determined that provide a route to solve a similar application more effectively.

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  - This study uses validated Large-eddy simulations to investigate the impact of the building exposure on the flow field around the principal building placed in the turbulent atmospheric boundary layer. The prismatic 1:3 square high-rise building model is analysed, considering three configurations: one isolated building model and two group arrangements of five geometrically identical buildings. Four exposure cases are singled out: model directly exposed to the wind, in single and group arrangement, partly exposed model placed in the channel between four buildings and completely shaded one by the building in front. Flow visualisation above the roof shows a strong dependency on the size of the separation zone and the exposure level. The results will be further used to predict the wind energy potential around buildings as well as the pedestrian level winds.

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  - One of the main challenges of urban wind energy harvesting is the understanding of the flow characteristics where urban wind turbines are to be installed. Among viable locations within the urban environment, high-rise buildings are particularly promising due to the elevated height and relatively undisturbed wind conditions. Most research studies on high-rise buildings deal with the calculation of the wind loads in terms of surface pressure. In the present paper, flow pattern characteristics are investigated for a typical high-rise building in a variety of configurations and wind directions in wind tunnel tests. The aim is to improve the understanding of the wind energy resource in the built environment and give designers meaningful data on the positioning strategy of wind turbines to improve performance. In addition, the study provides suitable and realistic turbulence characteristics to be reproduced in physical or numerical simulations of urban wind turbines for several locations above the roof region of the building. The study showed that at a height of 10 m from the roof surface, the flow resembles atmospheric turbulence with an enhanced turbulence intensity above 10% combined with large length scales of about 200 m. Results also showed that high-rise buildings in clusters might provide a very suitable configuration for the installation of urban wind turbines, although there is a strong difference between the performance of a wind turbine installed at the centre of the roof and one installed on the leeward and windward corners or edges, depending on the wind direction.

Most research studies on high-rise buildings deal with the calculation of the wind loads in terms of surface pressure. In the present paper, flow pattern characteristics are investigated for a typical high-rise building in a variety of configurations and wind directions in wind tunnel tests. The aim is to improve the understanding of the wind energy resource in the built environment and give designers meaningful data on the positioning strategy of wind turbines to improve performance. In addition, the study provides suitable and realistic turbulence characteristics to be reproduced in physical or numerical simulations of urban wind turbines for several locations above the roof region of the building. The study showed that at a height of 10 m from the roof surface, the flow resembles atmospheric turbulence with an enhanced turbulence intensity above 10% combined with large length scales of about 200 m. Results also showed that high-rise buildings in clusters might provide a very suitable configuration for the installation of urban wind turbines, although there is a strong difference between the performance of a wind turbine installed at the centre of the roof and one installed on the leeward and windward corners or edges, depending on the wind direction.",

AB  - The human migration from rural to urban areas has triggered a chain reaction causing the spiking energy demand of cities worldwide. High-rise buildings filling the urban skyline could potentially provide a means to improve the penetration of renewable wind energy by installing wind turbines at their rooftop. However, the above roof flow region has not received much attention and most results deal with low-rise buildings. This study investigates the flow pattern above the roof of a high-rise building by analysing velocity and pressure measurements performed in an atmospheric boundary layer wind tunnel, including four wind directions and two different roof shapes. Comparison of the surface pressure patterns on the flat roof with available low-rise building studies shows that the surface pressure contours are consistent for a given wind direction. At 0◦ wind direction, a separation bubble is detected, while cone vortices dominate at 30◦ and 45◦. The determining factor for the installation of small wind turbines is the vicinity to the roof. Thus, 45◦ wind direction shows to be the most desirable angle by bringing the substantial amplification of wind and keeping the turbulence intensity low. Decking the roof creates favourable characteristics by overcoming the sensitivity to the wind direction while preserving the speed-up effect.

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  - It is believed that the local topology has a significant effect on the wind flow pattern, wind velocity and turbulence intensity of the flow above the roof of buildings and thus is significantly influencing wind harvesting potential. This paper presents an experimental investigation, in which velocity field was measured above the roof 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. In addition, the surface pressure was also measured. The flow above the roof was measured for different wind angles: 0 , 15 , 30 , and 45 . Results showed that there is a significant influence of the upstream building on the wind characteristics above the principal one. In general the wind angle of 45  is shown to be the most desirable angle for wind energy harvesting. The results of this work provide for the first time a database for the validation of computational fluid dynamic simulations for flat roof that will hopefully be used for more detailed investigations for urban wind energy harvesting.

AB  - In this paper different mathematical models of the vehicle load are presented, depending on the one of the moving load types. In general, vehicle load models can be classified into two types: static and dynamic moving load models. Static moving load model is model with nonvarying load value and shape in time. Dynamic moving load model is defined by differential equations of motion where the road roughness function affects the solution. Due to this influence some of the differential equations cannot be solved analytically and the numerical approach has to be performed. Therefore, in this work Matlab Simulink models have been developed to solve this problem. Validation of Simulink models is carried out and presented for all analysed dynamic moving load models.

AB  - In order to increase wind energy harvesting from urban environment, the wind be- havior and the effect of the surrounding buildings needs to be fully understood. In this paper, wind tunnel experiments of the flow around a high-rise building with a height to width ratio of 3:1 surrounded by four high-rise buildings of the same geometry were performed to investigate the interference effect on the above roof flow. The buildings were mounted in an environmental boundary layer resembling that of a built environment and velocity measurements over the top of the principal building were performed. Four different wind angles, with respect to the side of the high-rise building, were investigated experimentally; 0°, 15°, 30°, and 45°.

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.

AB  - The widely used formulation of aeroelastic forces presented in the work of Scanlan and Tomko (1971) relies on the frequency dependent coefficients - flutter derivatives and wind tunnel experiments as their identification tool. The lack of analytical solution for flutter phenomena at bridges is related to the complexity of flow separations from a typical bridge deck. Numerical approaches can be considered for identification of aeroelastic forces. Nevertheless, it has to be kept in mind that numerical simulations are often jeopardized by the limitations related to poor detection of separation regions. In order to estimate the influence of these limitations over the computed flutter derivatives, this study employs 3D Large Eddy Simulation (LES) and 2D Unsteady Reynolds-Averaged Navier-Stokes (URANS) approaches.

AB  - Bridge flutter phenomenon presents an important criterion of instability, which should be considered in the bridge design phase. This paper presents different bridge flutter methods which can be used to solve the flutter problem. Most commonly used frequency-domain approach is based on the formulation of aero elastic forces with frequency dependent coefficients called flutter derivatives. The critical wind speed, as the main critical condition for the onset of flutter is obtained based on these aero elastic forces. Aero elastic forces can be also expressed in the time-domain, using so-called indicial functions. These functions are usually determined from the corresponding flutter derivatives.

AB  - This paper presents the results of numerical investigations of bridge aeroelasticity. In particular static
coefficients and instationary flutter derivatives for a symmetric bridge deck section using the Unsteady
Reynolds-Averaged Navier–Stokes (URANS) method are obtained. The numerical model uses the Finite
Volume discretization. The performed simulations are two-dimensional, and the turbulence is simulated by
the k–o-SST model. The numerical model is validated by force and pressure measurements from wind
tunnel experiments. The main goal of this work is to assess the capability of the numerically affordable
URANS method for estimating bridge flutter derivatives. In general the simulated aeroelastic surface
pressures and integrated forces are in good accordance with the aeroelastic pressure fields and forces
identified from comparative wind tunnel tests. This is particularly the case in the range of moderate
reduced velocities and for flow effects without dominant vortex shedding. The results demonstrate the
capability of the URANS method to derive bridge flutter derivatives and static coefficients in a numerically
effective and efficient way.

AB  - Zbog nedostatka stanova, zahvaljujući zakonskim rešenjima koja su to omogućavala, mnogi podstanari su svoje stambeno pitanje rešavali adaptacijom tavanskih prostora, ili nadziđivanjem postojećih zgrada. Nadziđivanja od jednog nivoanajčešće su rađena od drvenih konstrukcija sa minimalnom termičkom izolacijom, najčešće sa jednim slojem od 5 cm mineralne vune i opšivena limom. Slična je situacija i sa adaptiranim stambenim jedinicama u samim krovovima. Takva potkrovlja su prave energetske rupe i najveći potrošači energije. U radu se upoređuju dva tipična potkrovlja na jednoj istoj lokaciji, jedno uređeno savremeno u 2006.godini, sa zadovoljavajućom termičkom zaštitom zidova i svremenim PVC prozorima i drugo uređeno 80-tih godina sa velikim termičkim gubicima. Rezultati su takođe potvrđeni i snimcima dobijenim termovizijskom kamerom.
