The photographs of the flow pattern of a section perpendicular to the axis of a vortex ring were taken continuously with a high-speed video camera. The solid picture of a vortex ring was obtained by constructing these photographs with a computer graphics tool. Just after generating a vortex ring, the solid picture displayed a shape like the doughnut. The circumferential distortion appeared regularly on the surface of a solid picture as the vortex ring traveled downstream and the solid picture grew into the polygon. The distortion of the inner side on the circumferential surface of the solid picture was larger than that of the outer side on the surface. At final stage, i.e., just before collapse of the vortex ring, it seemed that a pair of rings might enclose the vortex core of vortex ring. These pairs of rings were not combined with the vortex core. The pair of rings may be constructed of a small pair of vortex ring, which are generated due to the centrifugal instability.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0028636010","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL SP-47","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"名城大学 理工学部"},{"subitem_text_value":"愛機製作所"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Meijo University Faculty of Science and Technology"},{"subitem_text_language":"en","subitem_text_value":"Aiki Seisakusho Ltd"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"奥出, 宗重"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大蔵, 信之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okude, Muneshige","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okura, Nobuyuki","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":"2020-02-10"}],"displaytype":"detail","filename":"nalsp0047010.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0047010.pdf","url":"https://jaxa.repo.nii.ac.jp/record/41370/files/nalsp0047010.pdf"},"version_id":"9b2c7c2c-a53c-49b2-99be-9a0e8dcea340"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"渦輪","subitem_subject_scheme":"Other"},{"subitem_subject":"変形過程","subitem_subject_scheme":"Other"},{"subitem_subject":"スモーク可視化手法","subitem_subject_scheme":"Other"},{"subitem_subject":"流れ模様","subitem_subject_scheme":"Other"},{"subitem_subject":"立体画像","subitem_subject_scheme":"Other"},{"subitem_subject":"コンピュータグラフィックス","subitem_subject_scheme":"Other"},{"subitem_subject":"周方向変形","subitem_subject_scheme":"Other"},{"subitem_subject":"渦核","subitem_subject_scheme":"Other"},{"subitem_subject":"遠心力不安定性","subitem_subject_scheme":"Other"},{"subitem_subject":"遷移過程","subitem_subject_scheme":"Other"},{"subitem_subject":"渦回転","subitem_subject_scheme":"Other"},{"subitem_subject":"vortex ring","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"deformation process","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"smoke visualization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flow pattern","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solid picture","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computer graphics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"circumferential distortion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"vortex core","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"centrifugal instability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"transition process","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"vortex rotation","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"渦輪の変形過程における構造","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"渦輪の変形過程における構造"}]},"item_type_id":"3","owner":"1","path":["1893","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"41370","relation_version_is_last":true,"title":["渦輪の変形過程における構造"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:02:03.186237+00:00"}
