The mechanism on why the noise becomes discrete and how the frequency is selected remains unclear. To reveal the mechanism, the boundary layer near the trailing edge on the pressure side was artificially disturbed with the use of distributed roughness elements. As a result, the separation is swept away and an acoustic sound is suppressed. The experimental results indicate that the frequency of trailing-edge noise is determined in separation region where mean velocity distribution has an inflection point accompanying reverse flow. These are necessary conditions for absolute instability.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063908019","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-07-026E","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 Aerospace Technology"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Institute of Aerospace Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小西, 康郁"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高木, 正平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Konishi, Yasufumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takagi, Shohei","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":"63908019.pdf","filesize":[{"value":"479.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"63908019.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5540/files/63908019.pdf"},"version_id":"250e1f81-8ab8-4e86-b996-70ad68c593bc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"空力騒音","subitem_subject_scheme":"Other"},{"subitem_subject":"翼型","subitem_subject_scheme":"Other"},{"subitem_subject":"後縁部","subitem_subject_scheme":"Other"},{"subitem_subject":"境界層","subitem_subject_scheme":"Other"},{"subitem_subject":"音圧","subitem_subject_scheme":"Other"},{"subitem_subject":"トルミーン-シュリヒティング波","subitem_subject_scheme":"Other"},{"subitem_subject":"周波数解析","subitem_subject_scheme":"Other"},{"subitem_subject":"速度分布","subitem_subject_scheme":"Other"},{"subitem_subject":"分散粗さ","subitem_subject_scheme":"Other"},{"subitem_subject":"aerodynamic noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"airfoil","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"trailing edge","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"boundary layer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sound pressure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Tollmien-Schlichting wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"frequency analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"velocity distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"distributed roughness","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Observation of the feedback loop associated with airfoil trailing-edge noise","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Observation of the feedback loop associated with airfoil trailing-edge noise","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["976","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5540","relation_version_is_last":true,"title":["Observation of the feedback loop associated with airfoil trailing-edge noise"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:12:28.370431+00:00"}
