Results of linear stability analyses for convective Mach number (M(sub c)) = 0.38 to M(sub c) = 1.51 show that the dominant mode depends upon the Mach numbers. For Mach number less than 1.5, the most unstable mode is antisymmetric. For M(sub c) over 1.5, the dominant mode is symmetric. 2-D spatially developing Direct Numerical Simulations (DNS) for M(sub c) = 1.51 show that the dilatation formed around the jet center plane is very strong, however, weak outside. It is confirmed by 3-D temporal DNS for M(sub c) = 1.13 that the structure of the flow field depends on the initial conditions, because the linear growth rates of the 2-D symmetric and 3-D antisymmetric mode are comparatively similar.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0028637016","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-48T","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":"電気通信大学"},{"subitem_text_value":"電気通信大学"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Electro-Communications"},{"subitem_text_language":"en","subitem_text_value":"University of Electro-Communications"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡辺, 大輔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"前川, 博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Daisuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Maekawa, Hiroshi","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":"2020-02-10"}],"displaytype":"detail","filename":"nalsp0048017.pdf","filesize":[{"value":"375.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0048017.pdf","url":"https://jaxa.repo.nii.ac.jp/record/41402/files/nalsp0048017.pdf"},"version_id":"9da24fa2-fb93-46ca-b5ac-2f9a057b2321"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"超音速平面噴流","subitem_subject_scheme":"Other"},{"subitem_subject":"対称性不安定モード","subitem_subject_scheme":"Other"},{"subitem_subject":"線形安定性解析","subitem_subject_scheme":"Other"},{"subitem_subject":"DNS","subitem_subject_scheme":"Other"},{"subitem_subject":"直接数値シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"噴流中心面","subitem_subject_scheme":"Other"},{"subitem_subject":"流れ場構造","subitem_subject_scheme":"Other"},{"subitem_subject":"線形成長速度","subitem_subject_scheme":"Other"},{"subitem_subject":"supersonic plane jet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"symmetric unstable mode","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"linear stability analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"DNS","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"direct numerical simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"jet center plane","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flow field structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"linear growth rate","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Structures in a supersonic plane jet due to symmetric/antisymmetric unstable modes at high Mach numbers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Structures in a supersonic plane jet due to symmetric/antisymmetric unstable modes at high Mach numbers","subitem_title_language":"en"}]},"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":"41402","relation_version_is_last":true,"title":["Structures in a supersonic plane jet due to symmetric/antisymmetric unstable modes at high Mach numbers"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:01:09.401879+00:00"}
