The pressure gradient is designed to obtain pure crossflow-dominated transition where the instability occurs through crossflow vortices that are generic to three-dimensional boundary layers. Flow-visualization and hot-wires are used to show that transition to turbulence occurs through a high-frequency, secondary instability that appears when the streamwise velocity profile is distorted by the stationary crossflow vortex. Multiple inflection points occur in the velocity profiles in very localized regions. These regions, characterized by spanwise velocity gradients that are the same magnitude as the normal-to-the-wall gradients, are the source of the sawtooth transition patterns. The travelling crossflow waves, although strongly amplified, appear to play only a passive role in the transition process. Detailed roughness measurements near the attachment line account for the strongly three-dimensional transition patterns that have been observed.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0015009","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-15","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":"東北大学工学部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tohoku University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小濱, 泰昭"}],"nameIdentifiers":[{"nameIdentifier":"463873","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kohama, Yasuaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"463874","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-28"}],"displaytype":"detail","filename":"nalsp0015009.pdf","filesize":[{"value":"271.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0015009.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43483/files/nalsp0015009.pdf"},"version_id":"3873073b-59b2-43e7-a19e-239acd23b187"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"randomization process; drag reduction; crossflow instability; inflexional instability","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"後退翼まわりの3次元境界層遷移","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"後退翼まわりの3次元境界層遷移"}]},"item_type_id":"3","owner":"1","path":["1893","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"43483","relation_version_is_last":true,"title":["後退翼まわりの3次元境界層遷移"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:13:44.155515+00:00"}
