KARI 중형 아음속 풍동용 돌풍 발생기의 수치해석
NUMERICAL ANALYSIS OF THE GUST GENERATOR FOR KARI LOW SPEED WIND TUNNEL
초록
The vortex convection and induced flow field behind the KARI 3m x 4m LSWT gust generator was computed by using Computational Fluid Dynamics. For the accurate simulation of vortex convection, inviscid, laminar, Spalart-Allmars k-e and k-w turbulence models were tested with the NAL gust generator configuration and Spalart-Allmaras turbulence model was selected for the prediction of induced flow field behind the KARI LSWT gust generator. The wind tunnel test was also carried out at KARI LSWT and the results were compared with CFD prediction.
