The turbulence intensity and integral scale were about ten times larger than those obtained by the conventional method and the turbulence Reynolds number, R(sub lambda), reached about 530. Due to the large integral scales of the present shear flows, the turbulence energy decayed downstream even when its total strain tau = (X/U(sub c))(partial derivative of U with respect to Y) was far larger than about four, as pointed out by Tavoularis & Karnik. When the total strain was smaller than about four, the power law was more successful than the exponential law in describing the decay of turbulence energy. The degree of anisotropy became independent of the initial condition for tau being approximately greater than six.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0001320009","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: NAL SP-36","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","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":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"豊橋技術科学大学"},{"subitem_text_value":"豊橋技術科学大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Toyohashi University of Technology"},{"subitem_text_language":"en","subitem_text_value":"Toyohashi University of Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"蒔田, 秀治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"関下, 信正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Makita, Hideharu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sekishita, Nobumasa","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":"2020-02-10"}],"displaytype":"detail","filename":"nalsp0036009.pdf","filesize":[{"value":"399.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0036009.pdf","url":"https://jaxa.repo.nii.ac.jp/record/37099/files/nalsp0036009.pdf"},"version_id":"f9e0665a-5f18-43c4-9c59-7c5c76d0d114"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"一様せん断乱流","subitem_subject_scheme":"Other"},{"subitem_subject":"せん断速度","subitem_subject_scheme":"Other"},{"subitem_subject":"せん断乱流発生装置","subitem_subject_scheme":"Other"},{"subitem_subject":"乱れ強度","subitem_subject_scheme":"Other"},{"subitem_subject":"大規模乱流場","subitem_subject_scheme":"Other"},{"subitem_subject":"乱流レイノルズ数","subitem_subject_scheme":"Other"},{"subitem_subject":"乱流エネルギー","subitem_subject_scheme":"Other"},{"subitem_subject":"指数則減衰","subitem_subject_scheme":"Other"},{"subitem_subject":"べき乗則減衰","subitem_subject_scheme":"Other"},{"subitem_subject":"異方度","subitem_subject_scheme":"Other"},{"subitem_subject":"uniformed shear turbulent flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shear rate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulence shear flow generator","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulence intensity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"large scale turbulent flow field","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulence Reynolds number","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulence energy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"exponential law decay","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"power law decay","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"degree of anisotropy","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":"大規模一様せん断乱流場の実現","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大規模一様せん断乱流場の実現"}]},"item_type_id":"5","owner":"1","path":["1891","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"37099","relation_version_is_last":true,"title":["大規模一様せん断乱流場の実現"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:26:02.097077+00:00"}
