While it is usually assumed that the difference increments tend to go to zero when the convergence or other issues like the order of accuracy is discussed, there are still problems in the numerical behaviors which should be discussed from the viewpoint that the difference approximation of interest is a 'discrete model' with the difference increments fixed to be some finite values. Two of such problems are discussed, the carbuncle instability and the unphysical dip of density that may happen with the occurrence of strong rarefaction waves. It seems that they are somehow related with the property of compressible Euler equations that the system has linearly degenerate fields while the whole system is nonlinear.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0048469039","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-04-012","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":"宇宙航空研究開発機構 総合技術研究本部"},{"subitem_text_value":"宇宙航空研究開発機構 総合技術研究本部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Institute of Space Technology and Aeronautics"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Institute of Space Technology and Aeronautics"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"相曽, 秀昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Abouziarov, Moustafa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aiso, Hideaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Abouziarov, Moustafa","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":"2020-01-16"}],"displaytype":"detail","filename":"48469039.pdf","filesize":[{"value":"823.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"48469039.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6479/files/48469039.pdf"},"version_id":"bec0ae0c-ad09-4511-9478-bb36bf9b8544"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"保存型差分スキーム","subitem_subject_scheme":"Other"},{"subitem_subject":"保存則","subitem_subject_scheme":"Other"},{"subitem_subject":"差分近似","subitem_subject_scheme":"Other"},{"subitem_subject":"オイラーの運動方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"圧縮性流れ","subitem_subject_scheme":"Other"},{"subitem_subject":"数値解析","subitem_subject_scheme":"Other"},{"subitem_subject":"離散モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"膨張波","subitem_subject_scheme":"Other"},{"subitem_subject":"conservative difference scheme","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"conservation law","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"difference approximation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Euler equation of motion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"compressible flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"discrete model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"expansion wave","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":"保存系に対する保存型差分近似スキームの問題点","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"保存系に対する保存型差分近似スキームの問題点"}]},"item_type_id":"5","owner":"1","path":["1073","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6479","relation_version_is_last":true,"title":["保存系に対する保存型差分近似スキームの問題点"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:55:01.253174+00:00"}
