Following the probe theory, the electron number density is calculated from the ion saturation current measured by the electro-static probes. Although the theory also requires information of flow velocity and electron temperature, neither of them strongly affects the electron number density, and CFD supplements these data. During the re-entry phase at altitudes from 100km to 75km/85km, OREX obtained valid ion saturation current data, which are almost free from under/over flow, and the probe are estimated to be kept under the breakdown temperature, 500 degrees celius . In this data analysis, the re-entry flow fields are simulated along the best estimated flight trajectory using the one-temperature model and Park's two-temperature one. The calculated electron number density is ranging from 1015 to 1019/m3. These results are directly compared with the numerical results, and the validity of the physical model and wall condition used in CFD is discussed.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0024018","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 SP-24","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":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"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"},{"subitem_text_value":"航空宇宙技術研究所"},{"subitem_text_value":"宇宙開発事業団"},{"subitem_text_value":"日産自動車"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"和田, 安弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 泰夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"秋元, 敏男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"安井, 英巳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wada, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Yasuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Akimoto, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yasui, Hidemi","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":"2020-01-28"}],"displaytype":"detail","filename":"nalsp0024018.pdf","filesize":[{"value":"954.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0024018.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43570/files/nalsp0024018.pdf"},"version_id":"fe0d1fd0-bf3d-4a7e-8e24-212bd4bc7736"}]},"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":"静電プローブのデータ解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"静電プローブのデータ解析"}]},"item_type_id":"3","owner":"1","path":["1893","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"43570","relation_version_is_last":true,"title":["静電プローブのデータ解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:11:41.216645+00:00"}
