First, a scalar linear advective equation in the two-dimensional space is solved by the present pointwise relaxation scheme for a second- and third-order spatial accuracy. The obtained results show favorable convergence properties while retaining the spatial accuracy of the scheme rigorously. The scheme is then extended to solve the Euler equations in the two-dimensional space. The computed transonic inviscid flowfield over RAE2822 wing section shows that the present scheme is capable of providing higher order accurate solutions with a rapid convergence property. It is found, however, that the convergence property highly depends on the choice of the local basis functions as well as on the form of the slope limiter.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0049212033","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-05-017","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":"東北大学 工学部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tohoku University Faculty of Engineering"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"澤田, 恵介"}],"nameIdentifiers":[{"nameIdentifier":"30877","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sawada, Keisuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"30878","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":"2020-01-16"}],"displaytype":"detail","filename":"49212033.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"49212033.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6166/files/49212033.pdf"},"version_id":"01eefe63-9987-4c14-9ca9-f59f44214f43"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ガレルキン法","subitem_subject_scheme":"Other"},{"subitem_subject":"陰的不連続ガレルキン法","subitem_subject_scheme":"Other"},{"subitem_subject":"非構造格子","subitem_subject_scheme":"Other"},{"subitem_subject":"収束","subitem_subject_scheme":"Other"},{"subitem_subject":"精度","subitem_subject_scheme":"Other"},{"subitem_subject":"基底関数","subitem_subject_scheme":"Other"},{"subitem_subject":"スロープリミッタ","subitem_subject_scheme":"Other"},{"subitem_subject":"数値解析","subitem_subject_scheme":"Other"},{"subitem_subject":"アルゴリズム","subitem_subject_scheme":"Other"},{"subitem_subject":"オイラーの運動方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"点緩和","subitem_subject_scheme":"Other"},{"subitem_subject":"Galerkin method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"implicit discontinuous Galerkin method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"unstructured grid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"convergence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"accuracy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"basis function","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"slope limiter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"algorithm","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Euler equation of motion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pointwise relaxation","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":"陰的Discontinuous Galerkin法による高次精度非構造格子法の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"陰的Discontinuous Galerkin法による高次精度非構造格子法の検討"}]},"item_type_id":"5","owner":"1","path":["1052","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6166","relation_version_is_last":true,"title":["陰的Discontinuous Galerkin法による高次精度非構造格子法の検討"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:00:55.662017+00:00"}
