Abstract
Increase in fatalities and injuries incurred by strong wind has recently observed in particular during typhoons which are responsible for about half of natural disasters in Korea. There are tens of disaster experience facilities in Korea for the purpose of disaster-safety education, which in general include experience wind tunnels. In order to satisfy required performance of the facility, it is essential to design the efficient wind tunnels which are usually allowed only for limited spatial capacity. This study presents the results of computational analysis of flow field inside the experience wind tunnel and spatial resistance parameter as a performance index of the facility. The analysis was carried out by using computational fluid dynamics (CFD) and, the velocity and pressure fields were analyzed. The results show that existing wind tunnel with U-shape wind pathway on the horizontal plane generated high nonuniformity in flow field as well as high spatial resistance. This study suggested a new configuration of the facility by placing the wind pathway on the vertical plane, which greatly increased the uniformity of the flow inside and reduce the spatial resistance.
