The injectant concentration obtained by LES was compared with acetone planer laser-induced fluorescence (PLIF) data. Numerical results reproduced the injectant mixing field not only in the averaged distribution but also in the turbulent features. Statistical analysis based on LES data evaluated the extent of the injectant turbulent diffusion flux and the injectant mean convective flux in a near-field cross-sectional plane: the mean convection of the injectant by counter-rotating vortex pair was larger than the turbulent diffusion except in the windward mixing layer between jet and crossflow. The vortex structure was visualized by the iso-surfaces of second invariant of the velocity gradient tensor. In the windward mixing layer, large-scale vortices randomly originated and extended mainly toward the downstream direction around the jet trajectory, meandering in the spanwise and wall-normal directions. These vortices deeply penetrate into the crossflow and contribute to the enhanced mixing by entraining a large amount of crossflow air in the near-field. Three-dimensional jet projection was produced by the windward large-scale vortex which has streamwise counter-rotating vortex pair.","subitem_description_type":"Other"}]},"item_5_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_5_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_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064967026","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-10-012","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東北大学"},{"subitem_text_value":"東北大学"},{"subitem_text_value":"東北大学"},{"subitem_text_value":"東北大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Tohoku University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡部, 潤也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河内, 俊憲"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"滝田, 謙一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"升谷, 五郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Junya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kouchi, Toshinori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takita, Kenichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Masuya, Goro","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":"2020-01-16"}],"displaytype":"detail","filename":"64967026.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64967026.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4733/files/64967026.pdf"},"version_id":"98dfbeb3-5598-48ec-a323-0408e2e0ead4"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"超音速流中における噴流の乱流混合のLES解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超音速流中における噴流の乱流混合のLES解析"}]},"item_type_id":"5","owner":"1","path":["925","1539","1883","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4733","relation_version_is_last":true,"title":["超音速流中における噴流の乱流混合のLES解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:32:47.542034+00:00"}
