International Conference Center, Waseda University), Shinjuku-ku, Tokyo, Japan, The Delayed Detached-Eddy-Simulation [Spalart et al., Theor. Comput. Fluid Dyn. 2006] has been improved [coined as “HR (High-Resolution)-DDES”], and applied to an unsteady turbulence simulation of a low speed buffet around a whole aircraft (NASA Common Research Model). The HR-DDES is not a single turbulence model. It is instead a framework comprised of DDES with calibrated turbulence model coefficients and improved LES (Large-Eddy-Simulation) / RANS (Reynolds-Averaged-Navier-Stokes) transition. As a result, the pressure distributions over the main wing are dramatically improved especially at 13.1% cross-section from the center-plane. The HR-DDES serves as a good alternative to the conventional counterpart for practitioners/users/aeronautical engineers without major coding or code modifications., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1930011009, レポート番号: JAXA-SP-19-007}, pages = {125--134}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {高解像度DDESによる低速バフェット解析}, volume = {JAXA-SP-19-007}, year = {2020} }
