A power law scheme, the control volume method is used inside the computational domain. In this study, Dean number, which is based upon the inlet bulk velocity, curvature ratio is from 100 to 500, and an aspect ratio of the duct is 1.0 and the curvature ratio is 10.0. Developing flow has a one-pair vortex secondary flow with Dean number 100, but in the case of Dean number 500, it has a two-pair vortex flow pattern at higher degree regions than 65 degrees from the duct inlet, which is caused by centrifugal force instability. Experimental data of Hille et al., is compared with the computer calculations and it has a good agreement with experimental results, except the inlet and the outlet region of the curved duct. This reason is considered that our inlet velocity is different from the experiment and we assume that the duct flow has a symmetric characteristics. However, Hill's flow has an asymmetric vortex pattern near the duct outlet regions.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0014024","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-14","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":"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":"National Aerospace Laboratory, Kakuda Research Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory, Kakuda Research Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory, Kakuda Research Center"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 仁"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石垣, 博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"望月, 宗和"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamada, Hitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishigaki, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mochizuki, Munekazu","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":"2020-01-28"}],"displaytype":"detail","filename":"nalsp0014024.pdf","filesize":[{"value":"373.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0014024.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43457/files/nalsp0014024.pdf"},"version_id":"2b69be6a-2c8a-4dd1-9a69-2ce9b9ba0658"}]},"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":"助走区間を含めた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":"助走区間を含めた矩形曲り管内の流れの数値解析"}]},"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":"43457","relation_version_is_last":true,"title":["助走区間を含めた矩形曲り管内の流れの数値解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:14:21.277299+00:00"}
