The present method takes a strategy to add non-linear localized artificial diffusivity to capture different types of discontinuities such as shock waves or material interfaces, while using a compact difference scheme. One-dimensional advection and modified Shu-Osher problems in supercritical flows are proposed in this study to assess the performance of the present method, in addition to an existing shock tube problem. Results for the advection problem show that the present method can be applied successfully to supercritical flows, including a trans-critical state, without any significant spurious oscillations, if initial startup errors are properly avoided. A localized artificial diffusivity, especially artificial thermal conductivity for temperature gradients, can effectively work on reducing numerical wiggles produced due to high density/temperature gradients. The modified Shu-Osher problem demonstrates the superiority of the present method in resolving high-frequency waves behind the shock wave even in a supercritical pressure condition, relative to a conventional low-order upwind-biased scheme. Results for a two-dimensional cryogenic plane jet in a supercritical pressure condition also demonstrate the capability of the present method for simulating the unsteady jet flow structures and the superiority for resolving the fluctuations with reasonable grid resolutions.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064967010","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-10-012","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"},{"subitem_text_value":"宇宙航空研究開発機構"}]},"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 (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Stanford University"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"寺島, 洋史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河合, 宗司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山西, 伸宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Terashima, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawai, Soshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamanishi, Nobuhiro","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":"64967010.pdf","filesize":[{"value":"985.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64967010.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4717/files/64967010.pdf"},"version_id":"047dcda3-eb1b-4037-994c-5baecd13cb2b"}]},"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":"高解像度コンパクト差分法を用いた超臨界圧極低温流体の乱流混合解析に向けて","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高解像度コンパクト差分法を用いた超臨界圧極低温流体の乱流混合解析に向けて"}]},"item_type_id":"5","owner":"1","path":["925","1539","1883","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4717","relation_version_is_last":true,"title":["高解像度コンパクト差分法を用いた超臨界圧極低温流体の乱流混合解析に向けて"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:33:09.057294+00:00"}
