It can be applied to estimate the overall characteristic of a fan. In this study, an analytical theory for the specific noise based on internal flow of a multiblade fan is proposed; moreover, the specific noise of the fan having an impeller with a different number of blades was discussed. The total pressure coefficient of the fan having 120 blades (MF120) became lower than the fan having 40 blades (MF40). On the other hand, the noise level of MF120 became 5.8 dB smaller than MF40 because the relative velocity was reduced by the slip. It was estimated by analyzing internal flow that the specific noise of MF120 was 4.3 dB smaller than MF40.","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 = Reports of the Faculty of Engineering, Nagasaki University vol.36(67) p.6-13 2006","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"108244","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sasaki, Soichi"}]},{"nameIdentifiers":[{"nameIdentifier":"108245","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kodama, Yoshio"}]},{"nameIdentifiers":[{"nameIdentifier":"108246","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hayashi, Hidechito"}]},{"nameIdentifiers":[{"nameIdentifier":"108247","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Uto, Taichi"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学工学部"}]},"item_3_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.lb.nagasaki-u.ac.jp/reports/kougaku/preview.php?id=29"}]}]},"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_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"P00006-P00013"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐々木, 壮一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"児玉, 好雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"林, 秀千人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宇都, 太一"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-24"}],"displaytype":"detail","filename":"36_67_02.pdf","filesize":[{"value":"483.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"36_67_02.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/25561/files/36_67_02.pdf"},"version_id":"1672ca50-0587-44e9-a004-9e2a45c20d02"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fan","subitem_subject_scheme":"Other"},{"subitem_subject":"Internal Flow","subitem_subject_scheme":"Other"},{"subitem_subject":"Aerodynamic Noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Vortex","subitem_subject_scheme":"Other"},{"subitem_subject":"Wake","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":"多翼ファンの比騒音に関する研究（羽根枚数の影響）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多翼ファンの比騒音に関する研究（羽根枚数の影響）"}]},"item_type_id":"3","owner":"2","path":["1919"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-01-12"},"publish_date":"2007-01-12","publish_status":"0","recid":"25561","relation_version_is_last":true,"title":["多翼ファンの比騒音に関する研究（羽根枚数の影響）"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T23:30:25.338591+00:00"}
