Transonic flows over two-dimensional forced oscillating airfoils with several reduced frequencies are first investigated for constructing a criterion for selecting the time stepping size, and then two and three-dimensional transonic flutter simulations are performed for evaluating the criterion. Results for the forced oscillating airfoil indicate that unsteady aerodynamic forces converge in a constant value as the time stepping size decreases and the time stepping size required the convergence of unsteady aerodynamic force depends on the reduced frequency. From these results, it turns out that 4,000 integration steps during one cycle of airfoil oscillations are enough for the estimation of the unsteady aerodynamic forces at any reduced frequency. The time stepping size is automatically decided by setting 4,000 integration steps during one cycle of airfoil oscillations. Results for two and three-dimensional transonic flutter simulations show that flutter boundaries can be accurately and effectively calculated based on the criterion.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0048469017","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":"東京大学 インテリジェント・モデリング・ラボラトリ"},{"subitem_text_value":"宇宙航空研究開発機構 宇宙科学研究本部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo Intelligent Modeling Laboratory"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Institute of Space and Astronautical Science"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"寺島, 洋史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤井, 孝蔵"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Terashima, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujii, Kozo","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":"48469017.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"48469017.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6457/files/48469017.pdf"},"version_id":"1794e9f2-47f2-47bf-adc9-0aae1a73e623"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"航空機設計","subitem_subject_scheme":"Other"},{"subitem_subject":"空力特性","subitem_subject_scheme":"Other"},{"subitem_subject":"遷音速フラッタ","subitem_subject_scheme":"Other"},{"subitem_subject":"遷音速飛行","subitem_subject_scheme":"Other"},{"subitem_subject":"CFD","subitem_subject_scheme":"Other"},{"subitem_subject":"非定常空気力学","subitem_subject_scheme":"Other"},{"subitem_subject":"翼型振動","subitem_subject_scheme":"Other"},{"subitem_subject":"Baldwin-Lomax乱流モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"陰解法","subitem_subject_scheme":"Other"},{"subitem_subject":"時間刻み幅","subitem_subject_scheme":"Other"},{"subitem_subject":"aircraft design","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerodynamic characteristic","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"transonic flutter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"transonic flight","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CFD","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"unsteady aerodynamics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"airfoil oscillation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Baldwin-Lomax turbulence model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"implicit method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"time stepping size","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":"遷音速フラッターシミュレーションにおける陰解法の時間刻み幅選定基準について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"遷音速フラッターシミュレーションにおける陰解法の時間刻み幅選定基準について"}]},"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":"6457","relation_version_is_last":true,"title":["遷音速フラッターシミュレーションにおける陰解法の時間刻み幅選定基準について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:55:24.257663+00:00"}
