International Conference Center, Waseda University), Shinjuku-ku, Tokyo, Japan, The paper presents the results of numerical simulations of the unsteady transonic flow around an oscillating shock-free airfoil (NLR7301) using the RANS code. The effects of the two turbulence models, namely, the Baldwin & Lomax's algebraic model and the Menter's SST k-omega model, on the unsteady transonic flows around the shock-free airfoil are examined in detail. It is shown that both the models give the fair agreement with the experimental data of pressure distributions and the lift and pitching moment for the shock-free condition while they give poor agreement with those of the experiment for the off-design condition where the strong shock wave exists on the upper surface of the airfoil., 形態: 図版あり, Physical characteristics: Original contains illustrations, 資料番号: AA1930011004, レポート番号: JAXA-SP-19-007}, pages = {89--98}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {振動するショック・フリー翼まわりの非定常遷音速流の数値シミュレーションに与える乱流モデルの効果について}, volume = {JAXA-SP-19-007}, year = {2020} }
