In this report, the primary instability in a weak free stream case is experimentally identified as locally generated Tollmien-Schlichting waves. This disturbance immediately breaks down with its deformation to the three-dimensional structure of the L shape and turbulent region starts to propagate in both streamwise and spanwise directions with forming a turbulent spot. Modal disturbances have chance to trigger the boundary layer transition induced by weak initial disturbance in the free stream., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064575005, レポート番号: JAXA-SP-09-014}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {弱い主流乱れにおける境界層遷移について}, volume = {JAXA-SP-09-014}, year = {2010} }
