The velocity fluctuation in this phenomenon comes to have a periodical regularity, and then this phenomenon is accompanied by a pure tone radiating from the leading edge of the pipe. Though the level of this tone is generally very small, a high sound level is produced by the coupling of the acoustic resonance of the pipe to the peridic oscillation of the flow in the jet. In this paper several methods are proposed in order to attenuate the acoustic resonace produced by this coupling, and the effect of attenuation for various methods is investigated experimentally.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等専門学校"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00179170","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-1909","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"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":"倉澤, 英夫"}],"nameIdentifiers":[{"nameIdentifier":"1055","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽田, 喜昭"}],"nameIdentifiers":[{"nameIdentifier":"1056","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小幡, 輝夫"}],"nameIdentifiers":[{"nameIdentifier":"1057","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-02-19"}],"displaytype":"detail","filename":"nagano_nct-25-01.pdf","filesize":[{"value":"771.2 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"nagano_nct-25-01.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/449/files/nagano_nct-25-01.pdf"},"version_id":"d98f9cac-aa5d-4170-ab16-85f5f41cfa69"}]},"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":"噴流せん断層の衝突による直管共鳴音に対する低減法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"噴流せん断層の衝突による直管共鳴音に対する低減法"}]},"item_type_id":"2","owner":"17","path":["33"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-19"},"publish_date":"2013-02-19","publish_status":"0","recid":"449","relation_version_is_last":true,"title":["噴流せん断層の衝突による直管共鳴音に対する低減法"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T16:07:34.577424+00:00"}
