This involves the evaluation of the radiation impedance of circum-ferential openings as well as the longitudinal wave motion in which the sound speed varies locally. An effect of the through flow deceleration is also examined. The results are shown in the form of a reflection coefficient which expresses the ratio of the incident and reflected waves at the diffuser inlet.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA2401356000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Aeronautical Science,University of Tokyo"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0372-1418","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00675986","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"NAGASHIMA, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TANIDA, Yoshimichi","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":"2020-01-24"}],"displaytype":"detail","filename":"SA2401356.pdf","filesize":[{"value":"622.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA2401356.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34551/files/SA2401356.pdf"},"version_id":"560237c8-3035-407f-ad96-34f1290021bc"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Sound Proapgation and Radiation through a Vaneless Diffuser","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sound Proapgation and Radiation through a Vaneless Diffuser","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1992"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34551","relation_version_is_last":true,"title":["Sound Proapgation and Radiation through a Vaneless Diffuser"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:39:42.393588+00:00"}
