At about Re = 3.6 x 10(exp 5), the drag coefficient curve is not continuous, but has a jump, and also a lift force actually acts on the cylinder. This phenomenon results from the sudden and asymmetric appearance of separation bubbles on both sides of the circular cylinder. The asymmetric formation of separation bubbles is the origin of lift. The Reynolds number, Re = 3.6 x 10(exp 5), is appropriately called the critical Reynolds number for the drag coefficient of a circular cylinder.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063908012","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-07-026E","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":"岐阜大学 工学部　機械工学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Gifu University Department of Mechanical Engineering, Faculty of Engineering"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松井, 辰彌"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsui, Tatsuya","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":"63908012.pdf","filesize":[{"value":"184.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"63908012.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5533/files/63908012.pdf"},"version_id":"3971ba89-86d4-4d83-bfe4-8eac7c234aeb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"円筒","subitem_subject_scheme":"Other"},{"subitem_subject":"一様流","subitem_subject_scheme":"Other"},{"subitem_subject":"臨界レイノルズ数","subitem_subject_scheme":"Other"},{"subitem_subject":"空力抵抗","subitem_subject_scheme":"Other"},{"subitem_subject":"抗力測定","subitem_subject_scheme":"Other"},{"subitem_subject":"圧力分布","subitem_subject_scheme":"Other"},{"subitem_subject":"剥離流","subitem_subject_scheme":"Other"},{"subitem_subject":"境界層剥離","subitem_subject_scheme":"Other"},{"subitem_subject":"剥離泡","subitem_subject_scheme":"Other"},{"subitem_subject":"揚力","subitem_subject_scheme":"Other"},{"subitem_subject":"乱流境界層","subitem_subject_scheme":"Other"},{"subitem_subject":"circular cylinder","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"uniform flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"critical Reynolds number","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerodynamic drag","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"drag measurement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pressure distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"separated flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"boundary layer separation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"separation bubble","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lift","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulent boundary layer","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"On the critical Reynolds number of the drag coefficient for a circular cylinder","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On the critical Reynolds number of the drag coefficient for a circular cylinder","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["976","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5533","relation_version_is_last":true,"title":["On the critical Reynolds number of the drag coefficient for a circular cylinder"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:12:41.561895+00:00"}
