Upstream of turbulent spots generation low frequency components of velocity fluctuations in a boundary layer are much larger than in free stream while high frequency components are dumped. The wall normal position of the maximum fluctuation corresponds with the maximum amplitude of the transient growth perturbation, and energy of disturbance linearly increases with distance from the leading edge but not exponentially. These results suggested that the primary instability in the natural transition corresponds to streaky structures predicted by the transient growth theory. This instability has notably different character from modal perturbations such as the Tollmien-Schlichting waves.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0001655008","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL SP-40","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_5_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_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東北大学"},{"subitem_text_value":"Royal Institute of Technology"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Royal Institute of Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松原, 雅春"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Alfredsson, P.
