Furthermore, the output characteristics and the aerodynamic noise of the turbine were measured by a wind tunnel. From comparison in the free torque condition, the noise of the tip speed ratio 12 became 7.6 dB larger than the noise of the tip speed ratio 8.2 due to the broadband noise in the high frequency domain. Because the flow was separated at the vicinity of the leading edge from the hub side to mid-span, the aerodynamic noise was concentrated at the leading edge, whereas the noise source of the blade tip side concentrated to the trailing edge side because the flow was attached to the blade. These results indicate that these perturbations in the high frequency domain become one of the important factors for the broadband noise source of the wind turbine.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学大学院工学研究科研究報告, 44(82), pp.1-6; 2014","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"21196","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sasaki, Soichi"}]},{"nameIdentifiers":[{"nameIdentifier":"21197","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Suzuki, Kota"}]},{"nameIdentifiers":[{"nameIdentifier":"21198","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sakada, Ryo"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学大学院工学研究科"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12601998","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18805574","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"1"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Engineering, Nagasaki University"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐々木, 壮一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木, 康太"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"坂田, 涼"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"44_82_1.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"44_82_1.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/5130/files/44_82_1.pdf"},"version_id":"3a453985-3d36-4c39-a71b-c3a595660068"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Wind Turbine","subitem_subject_scheme":"Other"},{"subitem_subject":"Aerodynamic Noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Wind Energy","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"小型プロペラ風車の出力特性と広帯域騒音に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"小型プロペラ風車の出力特性と広帯域騒音に関する研究"}]},"item_type_id":"3","owner":"2","path":["317"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-02-28"},"publish_date":"2014-02-28","publish_status":"0","recid":"5130","relation_version_is_last":true,"title":["小型プロペラ風車の出力特性と広帯域騒音に関する研究"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:11:34.877234+00:00"}
