It is shown that the outlet angle considerably effects on the turbulent noise but the skew angle of the blade effects barely on that. From the view points of aerodynamics and specific noise level, the optimum value of the outlet angle is about48 degree and that of the skew angle is about 10 degree. Moreover, we proposed a new method to calculate the width of wake which is an important parameter to controll the turbulent noise. We predicted the sound pressure level of the turbulent noise with the help of predicted width of wake and inlet relative velocity.The experimental values of the overall turbulent noise with L-weighting and A-weighting functions agreed well with predicted values.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"ターボ機械 31(4), p.237-245. 2003","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"97566","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ogino, Kazuo"}]},{"nameIdentifiers":[{"nameIdentifier":"97567","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Omori, Kazuya"}]},{"nameIdentifiers":[{"nameIdentifier":"97568","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kodama, Yoshio"}]},{"nameIdentifiers":[{"nameIdentifier":"97569","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hayashi, Hidechito"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本工業出版"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ターボ機械協会"}]},"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":"荻野, 和郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大森, 和也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"児玉, 好雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"林, 秀千人"}],"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":"Tuk31_237.pdf","filesize":[{"value":"315.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Tuk31_237.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/23128/files/Tuk31_237.pdf"},"version_id":"6e0315d2-fcc6-408f-9033-71e39bbf45a2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fluid Machine","subitem_subject_scheme":"Other"},{"subitem_subject":"Centrifugal Fan with Inducer","subitem_subject_scheme":"Other"},{"subitem_subject":"Fan","subitem_subject_scheme":"Other"},{"subitem_subject":"Turbulent Noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Specific Noise Level","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":"インデューサ付き遠心ファンの空力特性と騒音に関する研究(出口角およびスキュー角の影響)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"インデューサ付き遠心ファンの空力特性と騒音に関する研究(出口角およびスキュー角の影響)"}]},"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":"23128","relation_version_is_last":true,"title":["インデューサ付き遠心ファンの空力特性と騒音に関する研究(出口角およびスキュー角の影響)"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T00:59:47.173958+00:00"}
