doi:10.15793/kspr.2021.109..005

In this study, the wind environment around architectural heritage (Hwanggungwoo) located in urban area was numerically investigated using Computational Fluid Dynamics (CFD) model and Geographic Information System (GIS) data. In the four experimental cases of different inflow directions, the horizontal and vertical wind vector fields, and also the wind speeds around architectural heritage were analyzed to assess wind flow characteristics. As a result, the various phenomena such as flow separation and vortex was represented in the vector fields of horizontal and vertical flow, depending on the location and arrangement of high-rise buildings rather than the direction of inflow. The effect of wind was analyzed to be relatively significant at the southeast side of Hwanggungwoo in the case of northerly inflow for the height of 2m Above Ground Level(AGL), and also at the northeast side of Hwanggungwoo in the case of southerly inflow for the height of 10 m AGL. Thus, it was suggested that the effect of urbanization on architectural heritage should be assessed for wind environment.
