The experiment was done for NACA0012 and KORN 75-06-012 airfoils using a high-speed Schlieren VTR and pressure transducers. The analysis shows significant effects of the geometries and the Reynolds number. A 2-D N-S code was used to predict these phenomena. The result shows the macro-scale effects of airfoil geometry, Reynolds number and transition. A fine suructure of the motion such as the periodic trailing edge pressure history was captured. The basic frequency of the buffer motion agrees well with the experiment.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0996000","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: NAL TR-996T","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"廣瀬, 直喜"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三輪, 等"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIROSE, Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIWA, Hitoshi","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr0996t.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr0996t.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45255/files/naltr0996t.pdf"},"version_id":"65536001-65c6-4038-9436-6cba8ac515c3"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Computational and experimental Research on Buffet Phenomena of Transonic Airfoils","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Computational and experimental Research on Buffet Phenomena of Transonic Airfoils","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45255","relation_version_is_last":true,"title":["Computational and experimental Research on Buffet Phenomena of Transonic Airfoils"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:42:36.568164+00:00"}
