Accurate solutions were obtained for a Dean number up to 550 by using the power-law scheme, whereas up to 900 using the up-wind scheme. Numerical results were compared with available experimental and theoretical results, and it was subsequently determined that the friction factor is approximately 6％ larger when the secondary flow changes from a two vortex to a four vortex pattern(Dean Number=116). In addition, the friction factor's slope was found to be different in the two and four vortex regions. The calculated friction factor showed better agreement with the experimental resutls than did the other investigated theoretical results.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR1111000","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 TR-1111","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":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所角田支所"},{"subitem_text_value":"航空宇宙技術研究所角田支所"},{"subitem_text_value":"航空宇宙技術研究所角田支所"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kakuda Research Center, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Research Center, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Research Center, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 仁"}],"nameIdentifiers":[{"nameIdentifier":"474388","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石垣, 博"}],"nameIdentifiers":[{"nameIdentifier":"474389","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"望月, 宗和"}],"nameIdentifiers":[{"nameIdentifier":"474390","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YAMADA, Hitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474391","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ISHIGAKI, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474392","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MOCHIZUKI, Munekazu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474393","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr01111.pdf","filesize":[{"value":"654.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr01111.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45370/files/naltr01111.pdf"},"version_id":"628857a8-f043-4f3f-ac8e-b5fc06fcfbcc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Navier-Stokes Equation;  Curved Duct;  Dean Number;  Laminar flow;  numerical analysis","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":"矩形曲り管内の流れの数値解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"矩形曲り管内の流れの数値解析"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45370","relation_version_is_last":true,"title":["矩形曲り管内の流れの数値解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:40:39.115287+00:00"}
