Wind load simulation for high-speed train stations
A numerical simulation approach of wind load on buildings and wind tunnel experiment are presented in the present paper. Four Korean high-speed train (KTX) stations (Cheonan-Asan, Daejeon, Gwangmyeong and Gyeongju) were selected for this purpose. For the numerical simulation, 3-D incompressible flow with the standard k-epsilon turbulence model was adopted and the commercial CFD software STAR-CD was used. In order to validate results of the numerical solution, a wind tunnel experiment was performed. Results from the wind tunnel experiment using a scaled model and CFD of four high-speed train station buildings were compared, and good agreement was achieved for the wind loads on the station buildings. Hence, it was shown that CFD is a good tool for predicting the wind load of huge and irregularly shaped buildings.
