Numerical study for downburst wind and its load on high-rise building
Guoqing Huang,Weizhan Liu,Qiang Zhou,Zhitao Yan,Delong Zuo 한국풍공학회 2018 Wind and Structures, An International Journal (WAS Vol.27 No.2
3D simulations based on an impinging jet were carried out to investigate the flow field of a steady downburst and its effects on a high-rise building by applying the SST k-ω turbulence model. The vertical profile of radial wind speed obtained from the simulation was compared with experimental data and empirical models in order to validate the accuracy of the present numerical method. Then wind profiles and the influence of jet velocity and jet height were investigated. Focusing on a high-rise building, the flow structures around the building, pressure distributions on the building surfaces and aerodynamic forces were analyzed in order to enhance the understanding of wind load characteristics on a high-rise building immersed in a downburst.
