The quantities of the order of the square of the time-step are employed as unknowns of the scheme, which produces a ”δ2 (delta-square)-form” of the algorithm. The present scheme has second-order time accuracy without iteration. The iteration process in the algorithm, which the scheme has as an option, improves the numerical accuracy and robustness. Numerical experiments show that the present scheme is very good not only for an unsteady problem but also a steady problem.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0948000","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-948","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空気力学第二部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Second Aerodynamics Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松野, 謙一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MATSUNO, Kenichi","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr00948.pdf","filesize":[{"value":"572.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00948.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45207/files/naltr00948.pdf"},"version_id":"1abfacea-f7a2-4629-9cb3-f3cbe100071a"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"δ2-Correction Scheme for Unsteady Euler Equations","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"δ2-Correction Scheme for Unsteady Euler Equations","subitem_title_language":"en"}]},"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":"45207","relation_version_is_last":true,"title":["δ2-Correction Scheme for Unsteady Euler Equations"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:43:22.897965+00:00"}
