This study investigates the aerodynamic performance and pedestrian-level wind comfort of high-rise buildings with varying degrees of twist. Utilizing Computational Fluid Dynamics (CFD) simulations and the Spalart–Allmaras Detached Eddy Simulation (DES) model, the analysis was conducted on a 150-m-high building with a base dimension of 40 m × 35 m....

This study investigates the wind-induced interference effects on a triangular-shaped high-rise building under two distinct wind conditions: laminar flow and turbulent flow. While traditional design standards primarily address wind loads on regular geometries, there is a notable gap in research on the aerodynamic interference effects on irregular hi...

This study explores the wind-driven oscillation of the Y-plan shaped tall building by utilizing unsteady Computational Fluid Dynamics (CFD) in conjunction with structural modal analysis. Because tall structures are so near to one another, wind-driven interference effects between buildings have recently gained significant attention in structural eng...

This study investigated the aerodynamic behavior and structural responses of prismatic and tapered high-rise buildings under extreme wind conditions, focusing on peak wind-induced forces and moments. Using Computational Fluid Dynamics (CFD) simulations with a hybrid RANS/LES approach, the analysis explored the effects of turbulent inflow on the mea...

This paper describes the process for assessing explosion impact on structures due to liquefied petroleum gas (LPG) leakage, accompanied by a numerical modelling approach. Focused on the structures, the study aims to quantify overpressure from accidental explosions. In response, computational fluid dynamics (CFD) models have emerged as essential too...

The study investigates the altered wind pressure distribution resulting from modifications in wind flow patterns due to the presence of an interfering building. The primary focus centers on a prominent high-rise building with a rectangular cross section measuring 25 m × 50 m. An obstructing building, sharing the same cross-sectional shape but varyi...

In this paper, the dynamic analysis of wind effects on the bridge deck section is determined with the help of CFD simulation. As the wind tunnel testing approach is high-priced and time-consuming, there is a need for an alternative approach. The investigation on the bridge deck is carried out using ANSYS software. In this bridge deck design, with t...

The purpose of the study was to explore the interference effects on the wind-induced moment caused by two nearby high-rise structures. In order to use computational fluid dynamics (CFD), a stiff full-scale model of the buildings was created. Numerous (0°, 45° and 90°) wind incidence angles and two alternative model cross-sections (30 m × 30 m and 1...

Wind responses on a twin box girder bridge can be observed by a wind tunnel experiment or by having a full-scale setup if possible. Another possible approach is to go through a numerical approach, which is the CFD simulation of the atmospheric boundary layer surrounding the twin box girder bridge deck. A virtual wind tunnel CFD modelling simulation...

In the field of river engineering, complex flow behavior emerges at acute bends in waterways such as rivers or streams. Thus, understanding the flow structure, especially along the banks, is critical. Due to the river's turbulence , obtaining all necessary details through field observation and lab experiments is challenging, time-consuming, and exp...
