At a relatively low angle of attack, periodic vortex sheddings are reproduced, simultaneously generating a dipole sound from the trailing edge. By slightly altering inflow Mach number, the shedding frequency often changes drastically, presumably via the onset or offset of an acoustic feedback loop, which correlates an aerodynamic sound emission from the trailing edge, and an instability mechanism in the suction-side boundary layer of the foil. In this study, the phase difference between two different waves - an emitted sound wave and an induced instability wave, is statistically sampled and examined to clarify the on/off determination mechanism of the acoustic feedback loop.","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: AA0064967006","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研究開発本部流体グループ"},{"subitem_text_value":"宇宙航空研究開発機構研究開発本部流体グループ"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Fluid Dynamics Group, Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Fluid Dynamics Group, Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"跡部, 隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"池田, 友明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Atobe, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ikeda, Tomoaki","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":"64967006.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64967006.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4713/files/64967006.pdf"},"version_id":"bcda942c-e788-4b76-9a23-8a249a6343c8"}]},"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":"低Re数翼周り流れの境界層不安定と音響変動との相関について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低Re数翼周り流れの境界層不安定と音響変動との相関について"}]},"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":"4713","relation_version_is_last":true,"title":["低Re数翼周り流れの境界層不安定と音響変動との相関について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:33:14.735738+00:00"}
