The porous throat consists of a wall with 126 holes and a cavity underneath it so that the flow around the shock wave can circulate through the porous wall. The results show that no shock wave was observed at 80% of the porous region from the throat and that the pressure fluctuations in the transonic diffuser were greatly reduced by the porous throat. According to the frequency analysis, the frequency range attenuated by the porous region is between about 700 Hz and 1kHz and the frequencies lower than 700 Hz have still remained.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学工学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/5456"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0389-102X"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN0025048X"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学工学部紀要"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1995-09","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"50","bibliographicPageEnd":"25","bibliographicPageStart":"17"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"No50p17.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2003797/files/No50p17.pdf"},"version_id":"ea395ba9-a162-4334-965d-10b61276c429"}]},"item_title":"多孔スロートが遷音速ディフューザに及ぼす影響","item_type_id":"15","owner":"1","path":["1642837872220","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-03-31"},"publish_date":"2008-03-31","publish_status":"0","recid":"2003797","relation_version_is_last":true,"title":["多孔スロートが遷音速ディフューザに及ぼす影響"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T01:44:15.172701+00:00"}
