In this report, we proposed a new method to estimate the wake width which is an important parameter to calculate the turbulent noise. It was shown that the fan noise became lower when the bare ratio was from 9% to 25% and the outlet angle of scroll casing was about 20°. When the inlet/outlet area ratio of upper cascade was equal to that of the lower cascade and both of these are equal to about unity, the fan noise became lower. The predicted sound pressure level agrees well with the experimental values of the overall turbulent noise with L-weighting and A-weighting functions.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"ターボ機械 30(12), p.715-723. 2002","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"97549","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kodama, Yshio"}]},{"nameIdentifiers":[{"nameIdentifier":"97550","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sasaki, Soichi"}]},{"nameIdentifiers":[{"nameIdentifier":"97551","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hatakeyama, Maokoto"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本工業出版"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00004836","subitem_source_identifier_type":"NCID"}]},"item_2_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":"児玉, 好雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐々木, 壮一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"畠山, 真"}],"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":"Tuk30_715.pdf","filesize":[{"value":"332.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Tuk30_715.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/23126/files/Tuk30_715.pdf"},"version_id":"f244ddcb-4f13-4eda-8482-b83ba365e9d0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Dual-Cascades Centrifugal Fan","subitem_subject_scheme":"Other"},{"subitem_subject":"Fan noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Turbulent Noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Aerodynamic Characteristics","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"二重翼列遠心ファンの空力特性と乱流騒音について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"二重翼列遠心ファンの空力特性と乱流騒音について"}]},"item_type_id":"2","owner":"2","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-09-25"},"publish_date":"2007-09-25","publish_status":"0","recid":"23126","relation_version_is_last":true,"title":["二重翼列遠心ファンの空力特性と乱流騒音について"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T00:59:49.081110+00:00"}
