However it's origination is not known yet. Local vortex shedding frequency in spanwise direction is considered to differ from one point to another due to different local Strouhal number caused by flow three-dimensionality. Therefore, interaction between the different vortex shedding frequencies is considered to be the cause of the long time scale fluctuation. In this study, by means of short time Fourier transformation which is modified to have uniform local time response characteristics throughout entire measuring frequency range, modulation characteristics of quasi-instantaneous vortex shedding frequency observed by one point velocity measurement are investigated. Moreover, by means of the modified short time Fourier transformation, two point simultaneous velocity measurements were made to show the existence of the different vortex shedding frequencies at the same time in the spanwise direction.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"41498","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HANIU, Hiroyuki","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"41499","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MIYAKOSHI, Katsumi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"41500","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WU, Ping","nameLang":"en"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人日本機会学会"}]},"item_3_relation_191":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1299/kikaib.68.2557","subitem_relation_type_select":"DOI"}}]},"item_3_rights_192":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2002 一般社団法人日本機械学会"}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"羽二生, 博之","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"宮越, 勝美","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"呉, 平","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-22"}],"displaytype":"detail","filename":"2002.9_渦放出の不規則性における長周期変動（二次元円柱後流のスパン方向において同時に検出された異なる渦放出周波数）.pdf","filesize":[{"value":"734.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2002.9_渦放出の不規則性における長周期変動（二次元円柱後流のスパン方向において同時に検出された異なる渦放出周波数）.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/7990/files/2002.9_渦放出の不規則性における長周期変動（二次元円柱後流のスパン方向において同時に検出された異なる渦放出周波数）.pdf"},"version_id":"931f0d1e-beea-47de-a70d-21d8a9f4d62a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Vortex","subitem_subject_scheme":"Other"},{"subitem_subject":"Fluid Transients","subitem_subject_scheme":"Other"},{"subitem_subject":"Flow Measurements","subitem_subject_scheme":"Other"},{"subitem_subject":"Irreqularity","subitem_subject_scheme":"Other"},{"subitem_subject":"Circular Cylinder","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"渦放出の不規則性における長周期変動 （二次元円柱後流のスパン方向において同時に検出された異なる渦放出周波数）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"渦放出の不規則性における長周期変動 （二次元円柱後流のスパン方向において同時に検出された異なる渦放出周波数）","subitem_title_language":"ja"},{"subitem_title":"Long Time Scale Fluctuation in the Irregularity of Vortex Shedding （Different Vortex Shedding Frequencies Detected at the Same Time in the Spanwise Direction of Wake behaind a Two-Dimensional Circular Cylinder）","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-11-09"},"publish_date":"2015-11-09","publish_status":"0","recid":"7990","relation_version_is_last":true,"title":["渦放出の不規則性における長周期変動 （二次元円柱後流のスパン方向において同時に検出された異なる渦放出周波数）"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-13T02:21:30.225624+00:00"}
