The mean frequency is half of the frequency, f_v, of vortices shedding from a two-dimensional body that is installed in a jet nozzle contraction. Jet mixing has been enhanced by the flapping motion with a low frequency, f_3=f_1-f_2, which is considered to be caused by an inharmonic excitation. Vortical structures in the flapping jet are investigated by using flow visualization, image correlation and laser Doppler velocimetry. Vortices are seen to roll up asymmetrically at the jet nozzle exit, at a double frequency of that of the vortex shedding from the cylinder. Two types of vortices are formed by coalescence between these vortices and the vortices shedding from the cylinder. The periodicities of these two types of vortices are found to be equal. It is noted that vortices with f_1 or f_2 do not exist in the flow. The f_1 and f_2 are caused by the modulation of amplitude of the coalesced vortical structures with half of the flapping frequency, f_3.","subitem_description_type":"Abstract"}]},"item_3_description_194":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"34504","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MIYAKOSHI, Katsumi","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"34505","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HANIU, Hiroyuki","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"34506","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WU, Ping","nameLang":"en"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_3_rights_192":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"社団法人日本機械学会, 宮越勝美，羽二生博之，呉平, 日本機械学会論文集B編, 72(719), 2006, 1751-1758."}]},"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":"宮越, 勝美","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"羽二生, 博之","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":"5046.pdf","filesize":[{"value":"4.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"5046.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/6830/files/5046.pdf"},"version_id":"127bcc9f-07a9-4275-9d5f-e2f5264d3fe1"}]},"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":"ノズル内の二次元物体後流によってフラッピングする二次元噴流の渦構造(第２報，可視化観測および時系列画像相関解析)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ノズル内の二次元物体後流によってフラッピングする二次元噴流の渦構造(第２報，可視化観測および時系列画像相関解析)","subitem_title_language":"ja"},{"subitem_title":"Vortical Structures in a Two-Demensional Jet Under Flapping Motion Generated by a Wake of a Cylinder Installed in a Nozzle Contraction (2nd Report, Flow Visualization and Image Correlation Analysis)","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-04-19"},"publish_date":"2007-04-19","publish_status":"0","recid":"6830","relation_version_is_last":true,"title":["ノズル内の二次元物体後流によってフラッピングする二次元噴流の渦構造(第２報，可視化観測および時系列画像相関解析)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-13T02:20:11.457041+00:00"}
