Specifically, a big difference may be observed between the aeronautical field and the others represented by the mechanical one. The primary features of aeronautical Reynolds-averaged models are linked to the following three points: the coexistence of laminar and turbulent states, the complex ingredients such as density variation, and the high accuracy of computed results required for the design of airfoils etc. In this article, detailed discussions are made about the physical meaning of the Baldwin-Lomax (zero-equation) model, the Sparart-Allmaras (one-equation or turbulent-viscosity transport-equation) model, and the Menter (two-equation) model. The present article aims at understanding their essence from a physical viewpoint based on time scales.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: 図版あり","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1530014000","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: JAXA-RR-14-010","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1113","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1192675X","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構航空本部数値解析技術研究グループ(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構航空本部数値解析技術研究グループ(JAXA)"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Numerical Simulation Research Group, Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Numerical Simulation Research Group, Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉澤, 徴"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松尾, 裕一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshizawa, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Yuichi","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":"2020-01-15"}],"displaytype":"detail","filename":"AA1530014000.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1530014000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/1913/files/AA1530014000.pdf"},"version_id":"9167265e-5a0d-4926-bba4-414b22bfedbc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Reynolds-average","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulence model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aeronautical engineering","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"time scale","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"航空工学におけるレイノルズ平均乱流モデルの概観と時間スケールによる物理的意味の考察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"航空工学におけるレイノルズ平均乱流モデルの概観と時間スケールによる物理的意味の考察"}]},"item_type_id":"3","owner":"1","path":["65","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-04-10"},"publish_date":"2015-04-10","publish_status":"0","recid":"1913","relation_version_is_last":true,"title":["航空工学におけるレイノルズ平均乱流モデルの概観と時間スケールによる物理的意味の考察"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:32:32.936730+00:00"}
