The simulation started with an initial flow given as the basic flow plus small disturbances. When the simulation starts with smaller disturbance amplitude than the threshold value, the transition is induced by the well-known Tollmien-Schlichting wave instability. In this case, Lambda vortices induced by the nonlinear mechanism appear and produce peak-valley structures on the Tollmien-Schlichting wave, which have been observed in the experiments. On the other case starting with large disturbance amplitude than the threshold value, transient growth of streamwise vortices becomes to be dominant. Then, the amplified streamwise vortices collapse to three-dimensional vortices by the nonlinear mechanism.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0028636006","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL SP-47","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"電気通信大学 電気通信学部　機能機械工学科"},{"subitem_text_value":"航空宇宙技術研究所"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Electro-Communications Dept. of Mech.
