It is shown that the flow in the test chamber is uniform with respect to stagnation pressure and temperature within a circular cross section of 40 mm diameter at the stagnation temperature below 1200℃, thus indicating that the wind tunnel is adequate and satisfactory for making experimental investigation concerning ablation. Measurement of ablation rate at stagnation point and observation of detached shock wave are carried out by use of hemisphere-cylinder models made of teflon and the results are compared with existing theory. Agreement between theory and experiment is fairly good.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0125014000","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":"Bulletin of the Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Bulletin of the Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Bulletin of the Institute of Space and Aeronautical Science University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"河村, 龍馬"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"辛島, 桂一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 清"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWAMURA, Ryuma","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KARASIMA, Keiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SATO, Kiyoshi","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":"SA0125014.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0125014.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31943/files/SA0125014.pdf"},"version_id":"d897a1d8-5237-4c00-8a89-08e63e5b7249"}]},"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":"テフロンに関するよどみ点アブレーションの実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"テフロンに関するよどみ点アブレーションの実験"}]},"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":"31943","relation_version_is_last":true,"title":["テフロンに関するよどみ点アブレーションの実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:45:45.135640+00:00"}
