In this study, we replaced a tail fin in pitching motion with an oscillating wing having a drive unit. The flow fields around the wing were measured by stereoscopic particle image velocimetry. To visualize the 3D structure of the vortex in the wake, we determined the flow fields in equally spaced cross-sectional planes. We reconstructed the 3D velocity fields from the velocity data with three components in two dimensions. We visualized the 3D vortex structure from these velocity data and plotted an iso-vorticity surface. As a result, we found that the vortex ring was generated by the kick-down and kick-up motions of the wing and that the wake structure was comparable with that obtained numerically. Moreover, we calculated the propulsive forces from the temporal variations in circulation and in the area surrounded by the vortex ring.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Berlin Heidelberg"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s00348-013-1605-4","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":" ©Springer-Verlag Berlin Heidelberg 2013.The final publication is available at link.springer.com"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0723-4864","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10447762","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Imamura, Naoto"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuuchi, Kazuo"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-10-31"}],"displaytype":"detail","filename":"EF_54.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"EF_54","url":"https://tsukuba.repo.nii.ac.jp/record/31597/files/EF_54.pdf"},"version_id":"a41540a9-4f94-41b5-9704-dd7dc77c14cb"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-10-31"}],"displaytype":"preview","filename":"MOV1.mpg","filesize":[{"value":"24.6 MB"}],"format":"video/mpeg","licensetype":"license_note","mimetype":"video/mpeg","url":{"label":"Supplementary material 1","url":"https://tsukuba.repo.nii.ac.jp/record/31597/files/MOV1.mpg"},"version_id":"c997cb76-3b47-4760-8abb-e8a2ec086962"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-10-31"}],"displaytype":"preview","filename":"MOV2.mpg","filesize":[{"value":"15.1 MB"}],"format":"video/mpeg","licensetype":"license_note","mimetype":"video/mpeg","url":{"label":"Supplementary material 2","url":"https://tsukuba.repo.nii.ac.jp/record/31597/files/MOV2.mpg"},"version_id":"2ae1f6e5-be5f-4655-9e6d-ad1664be820d"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-10-31"}],"displaytype":"preview","filename":"MOV3.mpg","filesize":[{"value":"30.2 MB"}],"format":"video/mpeg","licensetype":"license_note","mimetype":"video/mpeg","url":{"label":"Supplementary material 3","url":"https://tsukuba.repo.nii.ac.jp/record/31597/files/MOV3.mpg"},"version_id":"28637d9f-86fc-4d9b-835f-e42124345306"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Relationship between vortex ring in tail fin wake and propulsive force","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Relationship between vortex ring in tail fin wake and propulsive force"}]},"item_type_id":"5","owner":"1","path":["834","394"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-31"},"publish_date":"2014-10-31","publish_status":"0","recid":"31597","relation_version_is_last":true,"title":["Relationship between vortex ring in tail fin wake and propulsive force"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:00:02.998242+00:00"}
