The design data was obtained by conducting the tests in simulated tunnel flow using two regulating valve models, with and without diffuser, and various perforated-plate models of differing porosity. The results of the tests are as follows; (1)the diffuser for the axisymmetrical regulating valve effectively extends the duration, (2)an experimental formula for the pressure loss coefficient was obtained as a function of porosity and pressure ratio, (3)acoustic efficiency of the perforated-plate is on the order of 10(exp -5).","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0465000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-465","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所空気力学第二部"},{"subitem_text_value":"航空宇宙技術研究所空気力学第二部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Second Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Second Aerodynamics Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"榊原, 盛三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"馬場, 滋夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAKAKIBARA, Seizo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"BABA, Shigeo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr00465.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00465.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44717/files/naltr00465.pdf"},"version_id":"61084f42-46b1-40a6-9055-114f1374b731"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"二次元風胴構成要素の研究(Ⅰ)-プラグ型調圧弁および多孔板の特性-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"二次元風胴構成要素の研究(Ⅰ)-プラグ型調圧弁および多孔板の特性-"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44717","relation_version_is_last":true,"title":["二次元風胴構成要素の研究(Ⅰ)-プラグ型調圧弁および多孔板の特性-"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:52:03.566821+00:00"}
