The Kevlar wall can keep the flow in the test section and it is acoustically transparent. JAXA installed the Kevlar wall in the test section of 2m×2m low speed wind tunnel. We measured transpiration velocities through Kevlar clothes for wall interference correction. It is found that the relationship between differential pressure and transpiration velocity can be modeled with an equation proposed by Devenport et al. Non-dimensional constants of the equation were obtained for two types of Kevlar clothes, and the transpiration velocities were modeled. In addition, the Kevlar cloth is stretched when it is used in wind tunnel, and therefore effects of the tension on the transpiration velocity were also investigated. However, we found that the tension does not affect the transpiration velocities.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1430003000","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: JAXA-RM-14-001","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1121","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":"AA11983593","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"宇宙航空研究開発機構航空本部数値解析技術研究グループ(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構航空本部風洞技術開発センター(JAXA)"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Numerical　Simulation　Research　Group, Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Wind Tunnel Technology Center, Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"伊藤, 美月"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石橋, 孝介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森, 浩一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中村, 佳朗"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"橋本, 敦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"浦, 弘樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ito, Mitsuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishibashi, Kosuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mori, Koichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamura, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hashimoto, Atsushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ura, Hiroki","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":"2020-01-15"}],"displaytype":"detail","filename":"AA1430003000.pdf","filesize":[{"value":"850.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1430003000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2486/files/AA1430003000.pdf"},"version_id":"88a8e57b-b200-4618-9717-4ad2c4851ec6"}]},"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":"ケブラー布の透過速度計測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ケブラー布の透過速度計測"}]},"item_type_id":"3","owner":"1","path":["1149","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"2486","relation_version_is_last":true,"title":["ケブラー布の透過速度計測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:21:45.949647+00:00"}
