Using the present equipment, the heat-transfer characteristics of a heated plate in sinesoidally pulsating flows were studied. At lower frequencies, the pulsation of main velocity has little influence upon the time-mean heat transfer coefficient, though it pulsates in the same order of magnitude as that of velocity. At higher frequencies, the pulsation reduces the heat transfer from the plate to flow with little amplitude in pulsation. The influences of flow pulsation upon the amplitude and the time-lag of velocity and temperature distributions in the boundary layer were also investigated.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0125439000","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_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","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":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeroautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeroautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeroautical Science University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"八田, 桂三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小竹, 進"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青木, 功"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HATTA, Keizo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOTAKE, Susumu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"AOKI, Isao","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":"SA0125439.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0125439.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32273/files/SA0125439.pdf"},"version_id":"3d29848e-0e4c-487d-9c30-80ff0d82a2da"}]},"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":"非定常気流の熱伝達","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"非定常気流の熱伝達"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32273","relation_version_is_last":true,"title":["非定常気流の熱伝達"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:36:46.902446+00:00"}
