The main objective is to investigate the dependencies of mean flow velocity and angle-of-attack. A rectangular wing with NACA0012 airfoil section is chosen as a model. The computed results are compared with that of wind tunnel experiments, which were also performed at JAXA for the purpose of CFD validation. The present unsteady computation using LES indicates that angle-of-attack has a great influence on the vortical structure around the wingtip. As the angle-of-attack increases, the merging location of two vortices, one at the side edge and another on the upper surface, moves to the upstream side. Consequently, the large pressure fluctuating region appears on the upper surface., 資料番号: AA0049212008, レポート番号: JAXA-SP-05-017}, pages = {53--58}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {翼端近傍流れ場の流速および迎角依存性に関するCFD解析}, volume = {JAXA-SP-05-017}, year = {2006} }
