A time-depended technique of solution is applied to solve the Euler equations for a compressible ideal gas. The characteristics of Mach disk obtained by the calculations are compared with the experiments and a good agreement is obtained. It is shown that the global jet structure with a nearly regular shock pattern which is stable and steady itself, is destabilized by the vortex rings (Kelvin-Helmholtz roll-up) on the jet boundary. These vortices produce shocks inside the jet, which are convected downstream with eddies. This strongly suggests that a time-independent or a time-con-verged solution cannot be expected without making a suitable time-averaging of the time-dependent solutions. Other important instabilities are also investigated.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0008009","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-8","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":"京都大学工学部航空工学教室"},{"subitem_text_value":"京都大学工学部航空工学教室"},{"subitem_text_value":"京都大学工学部航空工学教室"},{"subitem_text_value":"京都大学工学部航空工学教室"},{"subitem_text_value":"川崎重工業株式会社"},{"subitem_text_value":"川崎重工業株式会社"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautical Engineering, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautical Engineering, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautical Engineering, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautical Engineering, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Kawasaki Heavy Industries, Ltd."},{"subitem_text_language":"en","subitem_text_value":"Kawasaki Heavy Industries, Ltd."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石井, 隆次"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松田, 卓也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"梅田, 吉邦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"保田, 充彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"沢田, 恵介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"嶋, 英志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishii, Ryuji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuda, Takuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Umeda, Yoshikuni","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yasuda, Atsuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sawada, Keisuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shima, Eiji","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":"nalsp0008009.pdf","filesize":[{"value":"728.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0008009.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43262/files/nalsp0008009.pdf"},"version_id":"9e7dedd6-6fdb-42ca-8048-3bbcdad740f3"}]},"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":"超音速自由噴流の数値シュミレーション","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超音速自由噴流の数値シュミレーション"}]},"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":"43262","relation_version_is_last":true,"title":["超音速自由噴流の数値シュミレーション"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:19:00.250554+00:00"}
