The flow is found to deflect in the opposite side in every pair of adjacent expanded sections due to a pitchfork bifurcation and has a spatial period twice the periodicity of the channel geometry. Adding a localized disturbance at the inlet of the channel, the subsequent spatiotemporal development of the disturbance is observed. The disturbance induces two localized packet-like waves, one of which travels downstream reversing each deflection direction in expanded sections, and the other localized wave travels downstream forming a wave-packet. It is found that the wave-packet always splits into two intrinsic waves propagating with distinct phase velocities. The spatial structure and the phase velocity of the intrinsic waves are compared with the eigen mode of stability under two different periodic boundary conditions, one of which imposes the flow to have the same periodic length with that of the channel geometry and the other twice the periodic length together with a shift-and-reflect symmetry.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064237017","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: JAXA-SP-08-006","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","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":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"同志社大学大学院工学研究科"},{"subitem_text_value":"同志社大学大学院工学研究科"},{"subitem_text_value":"同志社大学大学院工学研究科"},{"subitem_text_value":"同志社大学大学院工学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Mechanical Engineering, Graduate School of Engineering, Doshisha University"},{"subitem_text_language":"en","subitem_text_value":"Department of Mechanical Engineering, Graduate School of Engineering, Doshisha University"},{"subitem_text_language":"en","subitem_text_value":"Department of Mechanical Engineering, Graduate School of Engineering, Doshisha University"},{"subitem_text_language":"en","subitem_text_value":"Department of Mechanical Engineering, Graduate School of Engineering, Doshisha University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"水島, 二郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高岡, 正憲"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山本, 寿一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐野, 太郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mizushima, Jiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takaoka, Masanori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamamoto, Hisakazu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sano, Taro","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":"2020-01-16"}],"displaytype":"detail","filename":"64237017.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64237017.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5475/files/64237017.pdf"},"version_id":"a0bf92d9-ee93-4c2d-b48b-3017933de587"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"symmetric channel, periodic sudden expansions, bifurcation, convective stability","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"周期的急拡大管流れの遷移と対流不安定性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"周期的急拡大管流れの遷移と対流不安定性"}]},"item_type_id":"5","owner":"1","path":["967","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5475","relation_version_is_last":true,"title":["周期的急拡大管流れの遷移と対流不安定性"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:14:16.321520+00:00"}
