It is effective for reducing the DFN level that the inlet nozzle is lengthened to the duct diameter and set the honeycomb in it. In the latter case, the DFN level can be reduced almost to the turbulent noise level. The DFN level was theoretically predicted. The prediction shows that the noise source concentrates to the leading edge of the blade. And the characteristic lengths are almost constant for any inlet distortion. The predicted noise level agrees with the experimental results.","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.733-740. 2002","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"97524","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hayashi, Hidechito"}]},{"nameIdentifiers":[{"nameIdentifier":"97525","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kodama, Yoshio"}]},{"nameIdentifiers":[{"nameIdentifier":"97526","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fuchigami, Shinnichirou"}]},{"nameIdentifiers":[{"nameIdentifier":"97527","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fukano, Toru"}]}]},"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":"林, 秀千人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"児玉, 好雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"淵上, 真一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"深野, 徹"}],"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_733.pdf","filesize":[{"value":"293.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Tuk30_733.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/23122/files/Tuk30_733.pdf"},"version_id":"8d0ecc1d-447d-40d9-9e85-1ca41f239a3a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Tubular fan","subitem_subject_scheme":"Other"},{"subitem_subject":"Interaction noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Inlet distortion","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":"チューブラー遠心送風機から発生する干渉騒音の特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"チューブラー遠心送風機から発生する干渉騒音の特性"}]},"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":"23122","relation_version_is_last":true,"title":["チューブラー遠心送風機から発生する干渉騒音の特性"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T01:00:07.164997+00:00"}
