Stationary rather than traveling mode has been predominantly observed in natural disk flow, spinning in still air, which is known to be a typical example of three-dimensional boundary layers. The present paper discusses this mode selection mechanism of crossflow instability on the basis of reviewing both experimental and theoretical research and making linear stability calculations inclusive of a wall-curvature term as well as streamline-curvature and non-parallel terms. This reveals that the wall curvature plays a key role in the mode selection mechanism of three-dimensional boundary layers and that initial amplitudes of unstable disturbances are of principal importance.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"ISSNの誤記: 1349-1148","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Incorrect ISSN: 1349-1148","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047414000","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: JAXA-RR-03-022E","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1113","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":"AA1192675X","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構 総合技術研究本部"},{"subitem_text_value":"帝京大学"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Institute of Space Technology and Aeronautics"},{"subitem_text_language":"en","subitem_text_value":"Teikyo University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高木, 正平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 信毅"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takagi, Shohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ito, Nobutake","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"47414000.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"47414000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2398/files/47414000.pdf"},"version_id":"983afffb-bf45-419d-873e-189a7ce07e4d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"3次元境界層","subitem_subject_scheme":"Other"},{"subitem_subject":"横流れ不安定性","subitem_subject_scheme":"Other"},{"subitem_subject":"モード選択機構","subitem_subject_scheme":"Other"},{"subitem_subject":"線形安定性","subitem_subject_scheme":"Other"},{"subitem_subject":"壁面曲率","subitem_subject_scheme":"Other"},{"subitem_subject":"流線曲率","subitem_subject_scheme":"Other"},{"subitem_subject":"レイノルズ数","subitem_subject_scheme":"Other"},{"subitem_subject":"three dimensional boundary layer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cross-flow instability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mode-selection mechanism","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"linear stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"wall curvature","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"streamline curvature","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Reynolds number","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"The mode-selection mechanism of cross-flow instability in three-dimensional boundary layers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The mode-selection mechanism of cross-flow instability in three-dimensional boundary layers","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["371","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"2398","relation_version_is_last":true,"title":["The mode-selection mechanism of cross-flow instability in three-dimensional boundary layers"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:23:16.403000+00:00"}
