Three test problems used for the open boundary condition evaluation are the backward facing step flow, the blunt based body flow and the rectangular cylinder obstacle flow in a channel. The investigated open boundary conditions are four. The author proposes to take the uniform inlet velocity as the phase speed in the Sommerfeld radiation condition. As the conclusion, this is shown to be the most excellent open boundary condition among the four open boundary conditions.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0001958045","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: NAL SP-41","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","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":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"畑山, 茂樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hatayama, Shigeki","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":"nalsp0041045.pdf","filesize":[{"value":"530.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0041045.pdf","url":"https://jaxa.repo.nii.ac.jp/record/37359/files/nalsp0041045.pdf"},"version_id":"3de09a21-4ec7-469c-973a-49f0918f518a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"非有限非圧縮性流","subitem_subject_scheme":"Other"},{"subitem_subject":"開境界条件","subitem_subject_scheme":"Other"},{"subitem_subject":"Leith型3次風上法","subitem_subject_scheme":"Other"},{"subitem_subject":"QUICKEST法","subitem_subject_scheme":"Other"},{"subitem_subject":"Sommerfeld放射条件","subitem_subject_scheme":"Other"},{"subitem_subject":"位相速度","subitem_subject_scheme":"Other"},{"subitem_subject":"流線","subitem_subject_scheme":"Other"},{"subitem_subject":"渦度","subitem_subject_scheme":"Other"},{"subitem_subject":"incompressible unbounded flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"open boundary condition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Leith type third order upwind scheme","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"QUICKEST scheme","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sommerfeld radiation condition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"phase speed","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stream line","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"vorticity","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"On the open boundary conditions for incompressive unbounded flows","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On the open boundary conditions for incompressive unbounded flows","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1891","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"37359","relation_version_is_last":true,"title":["On the open boundary conditions for incompressive unbounded flows"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:20:59.738857+00:00"}
