The propagation of flames in turbulent flow field depending on the equivalence ratios are represented by the extended G-equation model. The difference of the flame behaviors in the combustor is predicted for various equivalence ratios as observed in the experiment. While, the limit for the flame propagation toward the lean combustion region in the combustor is predicted to be leaner than the experimental data. The turbulent velocity field predicted by LES is also compared with the experimental data. Although the length of recirculation region generated by a swirling inlet flow is overestimated, the LES provided reasonable results in the averaged velocity field. The predicted results in the geometries of an experimental test piece and the modeled whole combustor are compared with each other. To investigate the affect of cut-out model of the annular combustor, the results for the turbulent flow field, the mixture fluctuation distribution and flame propagation did not greatly differ in the region where the experimental measurements conducted.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0048469033","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-04-012","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":"東京大学 大学院工学系研究科"},{"subitem_text_value":"東京大学 情報基盤センター"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo School of Engineering"},{"subitem_text_language":"en","subitem_text_value":"University of Tokyo Information Technology Center"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"冨永, 卓司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"谷口, 伸行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tominaga, Takuji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Taniguchi, Nobuyuki","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":"48469033.pdf","filesize":[{"value":"3.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"48469033.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6473/files/48469033.pdf"},"version_id":"b1578b7a-5515-4336-a634-1ce29c8ec67b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ラージエディーシミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"乱流燃焼","subitem_subject_scheme":"Other"},{"subitem_subject":"ガスタービンエンジン","subitem_subject_scheme":"Other"},{"subitem_subject":"燃焼室","subitem_subject_scheme":"Other"},{"subitem_subject":"火炎伝播","subitem_subject_scheme":"Other"},{"subitem_subject":"当量比","subitem_subject_scheme":"Other"},{"subitem_subject":"希薄燃焼","subitem_subject_scheme":"Other"},{"subitem_subject":"アルゴリズム","subitem_subject_scheme":"Other"},{"subitem_subject":"Large Eddy Simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulent combustion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gas turbine engine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"combustion chamber","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flame propagation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"equivalence ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lean combustion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"algorithm","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"G方程式を用いたガスタービン燃焼器内の乱流燃焼場のLES","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"G方程式を用いたガスタービン燃焼器内の乱流燃焼場のLES"}]},"item_type_id":"5","owner":"1","path":["1073","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6473","relation_version_is_last":true,"title":["G方程式を用いたガスタービン燃焼器内の乱流燃焼場のLES"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:55:07.372874+00:00"}
