The vortical flow structures around the NACA0012 are known to be similar to that of a flap-edge. Therefore, it is assumed that noise generation mechanism is similar as well, although its geometry is simpler than a flap-edge. Since the Reynolds number of the flow is high, a zonal LES/RANS hybrid method is used to reduce the overall computational cost. The power spectral density of the pressure coefficient is compared with the experiment, and several issues regarding, the number of sub iteration for implicit time integration, sensitivity to Smagorinsky constant, grid overlap points at block-block interface, and grid resolution, are discussed. Subsequently, two longitudinal vortical structures around the wingtip, that show different characteristics, are investigated to understand its generation mechanism.","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: AA0064672024","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-09-011","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":"宇宙航空研究開発機構"},{"subitem_text_value":"菱友システムズ"},{"subitem_text_value":"宇宙航空研究開発機構"},{"subitem_text_value":"宇宙航空研究開発機構"},{"subitem_text_value":"宇宙航空研究開発機構"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Ryoyu Systems"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"今村, 太郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平井, 亨"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"横川, 譲"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"榎本, 俊治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山本, 一臣"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Imamura, Taro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirai, Tohru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yokokawa, Yuzuru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Enomoto, Shunji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamamoto, Kazuomi","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":"64672024.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64672024.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4922/files/64672024.pdf"},"version_id":"f1315c04-a353-4090-b452-6e9d288e3d50"}]},"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":"NACA0012切り落とし翼端から発生する渦のLES解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"NACA0012切り落とし翼端から発生する渦のLES解析"}]},"item_type_id":"5","owner":"1","path":["945","1540","1884","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4922","relation_version_is_last":true,"title":["NACA0012切り落とし翼端から発生する渦のLES解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:28:46.763183+00:00"}
