The absolute velocity of main flow domain in the meridional plane of the propeller fan became 30 m/s while the velocity of the inclined plane in the case of 40 degree was decreased to 25 m/s. The velocity fluctuations on the vertical plane in the wake were weakened at the diagonal line of the duct by the velocity deformation formed to the circumferential direction around the impeller. Then the circular wake formed in the propeller fan was broken by the velocity deformation. It is considered that the discrete frequency noise of the propeller fan in the second harmonics became large because the fourteen dynamic rotors and the pseudo four stators made by the non-homogenous circular wake resonated.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学工学部研究報告, 41(76), pp.1-6; 2011","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"53914","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sasaki, Soichi"}]},{"nameIdentifiers":[{"nameIdentifier":"53915","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fukuda, Masaharu"}]},{"nameIdentifiers":[{"nameIdentifier":"53916","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Mukai, Shogo"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学工学部"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12080680","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_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Faculty 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":"福田, 雅治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"向井, 将伍"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"41_76_1.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"41_76_1.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/14627/files/41_76_1.pdf"},"version_id":"222cdcb8-40f7-4427-ade3-310a328ecf3e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fan","subitem_subject_scheme":"Other"},{"subitem_subject":"Resonance","subitem_subject_scheme":"Other"},{"subitem_subject":"Aerodynamic Noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Wake","subitem_subject_scheme":"Other"},{"subitem_subject":"Internal Flow","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":"プロペラファンの非一様な環状後流と離散周波数騒音","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"プロペラファンの非一様な環状後流と離散周波数騒音"}]},"item_type_id":"3","owner":"2","path":["1220"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-02-10"},"publish_date":"2011-02-10","publish_status":"0","recid":"14627","relation_version_is_last":true,"title":["プロペラファンの非一様な環状後流と離散周波数騒音"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T00:16:48.823646+00:00"}
