| Popis: | 第47回流体力学講演会/第33回航空宇宙数値シミュレーション技術シンポジウム (2015年7月2日-3日. 東京大学生産技術研究所), 目黒区, 東京 47th Fluid Dynamics Conference /the 33rd Aerospace Numerical Simulation Symposium (July 2-3, 2015. Institute of Industrial Science , the University of Tokyo), Meguro-ku, Tokyo, Japan Predicting buffet over an airfoil is one of the challenging problems for current CFD because the phenomenon is complex and unsteady. In this paper, we conduct a simulation of the transonic buffet over a super-critical airfoil using FaSTAR code which is the unstructured CFD code developed by JAXA. Zonal DES approach is employed for the flow simulations, which is RANS/LES hybrid approach. Results are compared with the past research and the experimental data. 形態: カラー図版あり Physical characteristics: Original contains color illustrations 資料番号: AA1630005028 レポート番号: JAXA-SP-15-013 |
