In wind farms, wind turbines are installed collectively and that results in a reduction of power generation. This problem requires proper designs of wind farms and knowledge about a wind turbine wake. Recent studies have revealed that tip vortices have a strong influence on wind turbine wakes. In this study, wakes from Mie University wind turbine of varying operating conditions are calculated by using Computational Fluid Dynamics (CFD), and energy transitions in the wind turbine wakes are examined. In the calculations, release frequencies of tip vortices are changed by changing tip speed ratio and the number of blades. The CFD results show the same trend of kinetic energy transition when the vortex release frequency is close. And the CFD results also show that when vortex release frequency becomes higher, a minimum value of energy becomes smaller and energy recovery rate becomes larger. This tendency is considered to be caused by the fact that when the frequency becomes higher, the interval between the vortices becomes narrower and the barrier effect which restrains momentum exchange between a wake and a mainstream becomes greater.","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: AA1730011007","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-17-004","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(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"東京大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"The University of Tokyo"},{"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)"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"篠崎, 陽介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田辺, 安忠"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青山, 剛史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松尾, 裕一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荒川, 忠一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"飯田, 誠"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shinozaki, Yosuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanabe, Yasutada","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoyama, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Yuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Arakawa, Chuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iida, Makoto","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":"2020-01-15"}],"displaytype":"detail","filename":"AA1730011007.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1730011007.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3241/files/AA1730011007.pdf"},"version_id":"10059a41-c5d1-4226-b841-725b4182b403"}]},"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":"風車後流に対する翼端渦放出周期の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"風車後流に対する翼端渦放出周期の影響"}]},"item_type_id":"5","owner":"1","path":["1532","1876","1891","1978"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-28"},"publish_date":"2017-12-28","publish_status":"0","recid":"3241","relation_version_is_last":true,"title":["風車後流に対する翼端渦放出周期の影響"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:06:29.870707+00:00"}
