This paper presents numerical simulations of pressure control at a ventilated adaptive-wall for a two-dimensional wind-tunnel. Numerical inner and outer flows of the wind-tunnel are calculated simultaneously and independently on the basis of Euler equations using a finite difference method in the Cartesian grid. The concept of an adaptive-wall requires that the inner flow matches the outer flow at control surfaces. This requirement is satisfied by matching of the flow direction at the control surfaces. Numerical adaptive-wall wind-tunnel tests of the NACA0012 airfoil are being performed to demonstrate the possible applications of adaptive-wall control. Several calculated results of airfoil abilities in the numerical wind-tunnel are compared with experimental and other calculated results.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0000589000","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 TR-1295","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":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"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 空力性能部"},{"subitem_text_value":"航空宇宙技術研究所 空力性能部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Aircraft Aerodynamics Division"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Aircraft Aerodynamics Division"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 正義"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"桑野, 尚明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamura, Masayoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kuwano, Naoaki","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":"2020-01-27"}],"displaytype":"detail","filename":"naltr01295.pdf","filesize":[{"value":"900.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr01295.pdf","url":"https://jaxa.repo.nii.ac.jp/record/39801/files/naltr01295.pdf"},"version_id":"4dff24aa-3ec4-4863-a65a-868e8fcab01b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"適応壁風洞","subitem_subject_scheme":"Other"},{"subitem_subject":"適応壁圧力制御","subitem_subject_scheme":"Other"},{"subitem_subject":"空力適応壁","subitem_subject_scheme":"Other"},{"subitem_subject":"圧力制御シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"数値流れシミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"空力干渉","subitem_subject_scheme":"Other"},{"subitem_subject":"空力解析","subitem_subject_scheme":"Other"},{"subitem_subject":"超音速流","subitem_subject_scheme":"Other"},{"subitem_subject":"亜音速流","subitem_subject_scheme":"Other"},{"subitem_subject":"翼型空力特性","subitem_subject_scheme":"Other"},{"subitem_subject":"adaptive wall wind tunnel","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"adaptive wall pressure control","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ventilated adaptive wall","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pressure control simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical flow simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerodynamic interference","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerodynamic analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"supersonic flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"subsonic flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"airfoil aerodynamic characteristic","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"適応壁圧力制御シミュレーション","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"適応壁圧力制御シミュレーション"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"39801","relation_version_is_last":true,"title":["適応壁圧力制御シミュレーション"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:19:06.431265+00:00"}
