The number of rotations per unit time increases with velocity, but it keeps constant in non-dimensional form.

Drag, lift and momentum of the cylinder in rotation are measured by a strain gauge balance at various cases of velocity and pressure. The results of the measurements are compared with numerical simulations by discrete vortex method.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166547000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"お茶の水大学理学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大島, 裕子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OSHIMA, Yuko","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0166547.pdf","filesize":[{"value":"692.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166547.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32791/files/SA0166547.pdf"},"version_id":"b83c5e0d-fe97-465a-aab8-77a105e46a11"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"楕円柱の自励回転の実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"楕円柱の自励回転の実験"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32791","relation_version_is_last":true,"title":["楕円柱の自励回転の実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:23:59.283534+00:00"}
