The outer cylindrical boundary of the flow field is assumed to be fixed, whereas the inner cylinder rotates together with the two disks. The flow is not only symmetric with respect to the inter-disk midplane but also axisymmetric around the axis of rotation at small Reynolds numbers. The axisymmetry of the flow field is broken due to instability at high Reynolds numbers. Such an instability occurs for small gap ratios, the ratio of the gap between two disks to the radius of the annulus, and yields a polygonal flow pattern in a plane normal to the rotation axis. We identified two kinds of three dimensional unsteady flow by numerical simulations, one of which is asymmetric with respect to the inter-disk midplane and the other has a shift-and-reflect symmetry with the midplane, and compared them with those obtained by experiment. We found that the critical Reynolds number at which the axisymmetric makes a transition to unsteady 3D flow is smaller than those evaluated in previous papers, although the flow patterns are consistent with those reported in them.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0049208024","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-05-012","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"同志社大学 工学部　機械工学科"},{"subitem_text_value":"同志社大学 工学部　機械工学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Doshisha University Department of Mechanical Engineering, Faculty of Engineering"},{"subitem_text_language":"en","subitem_text_value":"Doshisha University Department of Mechanical Engineering, Faculty of Engineering"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三浦, 知仁"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"水島, 二郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miura, Tomohito","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mizushima, Jiro","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":"2020-01-16"}],"displaytype":"detail","filename":"49208024.pdf","filesize":[{"value":"886.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"49208024.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6206/files/49208024.pdf"},"version_id":"c9cb6b4a-d5f2-4bdc-9004-cd7b31f94d56"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Couette流","subitem_subject_scheme":"Other"},{"subitem_subject":"回転円盤","subitem_subject_scheme":"Other"},{"subitem_subject":"流れの安定性","subitem_subject_scheme":"Other"},{"subitem_subject":"流れの可視化","subitem_subject_scheme":"Other"},{"subitem_subject":"流れ分布","subitem_subject_scheme":"Other"},{"subitem_subject":"非定常流","subitem_subject_scheme":"Other"},{"subitem_subject":"数値解析","subitem_subject_scheme":"Other"},{"subitem_subject":"アスペクト比","subitem_subject_scheme":"Other"},{"subitem_subject":"レイノルズ数","subitem_subject_scheme":"Other"},{"subitem_subject":"Couette flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"rotating disk","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flow stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flow visualization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flow distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"unsteady flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aspect ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Reynolds number","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"回転2円板間流れのパターン形成","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"回転2円板間流れのパターン形成"}]},"item_type_id":"5","owner":"1","path":["1056","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6206","relation_version_is_last":true,"title":["回転2円板間流れのパターン形成"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:00:05.035523+00:00"}
