Wind Effects on Non-Regular Building Shapes as a Function of Velocity Angle: A Computational Fluid Dynamics (CFD) Study
Keywords:
Wind load, Tall buildings, Computational Fluid Dynamics, Irregular Shapes, Velocity, k- ε modelAbstract
This study investigates how different velocity angles affect the aerodynamics of irregular shape structures, focusing on Y, L, and + configurations. Its main goal is to evaluate how varying velocity angles influence the aerodynamic characteristics of these designs. Additionally, it explores the impact of mesh finite element density on result accuracy. Computational Fluid Dynamics (CFD) is employed to analyse the effects of 50 m/s wind speed on these buildings, providing a robust solver and extensive pre and post-processing capabilities for a comprehensive study. Pre-processing involves geometry modeling, meshing, material specification, and boundary condition setup. The k-ε model and momentum, fluid energy, and continuity equations are utilised for response calculation. Post-processing includes the examination of velocity profiles, path lines, pressure distributions, and forces. This research contributes to understanding how building shape, wind angles, and mesh density influence fluid dynamics around structures, aiding in the development of more slender, efficient, and resilient structures in the face of climate change.
