Yonago Convention Center BiG SHiP), Yonago, Tottori Japan, In this paper, we try to introduce the characteristic time scales intrinsic to turbulent separated flows into the RANS turbulence modeling, and propose a k‐epsilon type model in which the turbulent eddy viscosity is modified by the correction factor based on the time scales. We also show pros and cons of the proposed model by applying it to the separated airfoil flows and the backward facing step flows., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064967008, レポート番号: JAXA-SP-10-012}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {航空宇宙の剥離流への時間スケールに着目した乱流モデルの適用}, volume = {JAXA-SP-10-012}, year = {2011} }
