01. Experimental/Computational Fluid Dynamics

As urban areas become denser and high-rise buildings dominate, understanding the aerodynamic phenomena around skywalks connecting high-rise buildings is essential. This study investigates the impact of skywalk configurations on wind characteristics around skywalks and high-rise buildings, focusing on structural stability, pedestrian comfort, and aerodynamic efficiency. Using computational fluid dynamics (CFD), the research examines the configuration of skywalks between tall buildings arranged in a 2 x 2 formation, each 90 meters tall. The 3D Reynolds-averaged Navier-Stokes (RANS) simulations employ the Reynolds Stress Model (RSM) turbulence model to accurately capture the complex flow dynamics. The results demonstrate that skywalks significantly alter wind flow around both the skywalk and the buildings, affecting wind speeds and pressures. It highlights the critical role of wind dynamics in urban planning and architectural design. By incorporating aerodynamic considerations into the design and construction of skywalks, cities can achieve better wind management, ensuring safer and more comfortable pedestrian pathways. Additionally, this research contributes to developing more sustainable and livable high-rise urban environments.
