Two different kinds of unstable disturbances, which exponentially grow in space, were observed. The minor disturbance is due to convective instability, while the origin of the major one may be attributed to absolute instability. Theoretical comparison is necessary to identify these disturbances., 資料番号: AA0063156004, レポート番号: JAXA-SP-06-013}, pages = {13--14}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {カルマン渦列の周波数選択性}, volume = {JAXA-SP-06-013}, year = {2007} }
