When the Reynolds number Reλ is increased up to Reλ = 585, the scalar flux spectrum tends to obey the power law k-7/3, as predicted by Lumley [J. Atmos. Sci. 21, 99 (1964); Phys. Fluids 10, 855 (1967)] , with a nondimensional constant of Cuθ = 1.50±0.08 at Reλ = 585. The Reλ effect on the scaling of the scalar flux spectrum is well compensated using the mean molecular destruction of the scalar flux uθ. The Reλ dependence of Cuθ is also compared with the results of previous studies, and its asymptotic state at an infinite Reynolds number is discussed.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8701","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000030345946","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000030345946"}],"names":[{"name":"渡邊, 威"}]},{"familyNames":[{"familyName":"Gotoh","familyNameLang":"en"},{"familyName":"後藤","familyNameLang":"ja"},{"familyName":"ゴトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Toshiyuki","givenNameLang":"en"},{"givenName":"俊幸","givenNameLang":"ja"},{"givenName":"トシユキ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"8672","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000070162154","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000070162154"}],"names":[{"name":"Gotoh, Toshiyuki","nameLang":"en"},{"name":"後藤, 俊幸","nameLang":"ja"},{"name":"ゴトウ, トシユキ","nameLang":"ja-Kana"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics","subitem_publisher_language":"en"}]},"item_10001_relation_34":{"attribute_name":"item_10001_relation_34","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1063/1.2821906"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1063/1.2821906","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1070-6631","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"item_10001_source_id_32","attribute_value_mlt":[{"subitem_source_identifier":"AA10986203","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Watanabe, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8701","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000030345946","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000030345946"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Gotoh, Toshiyuki","creatorNameLang":"en"},{"creatorName":"後藤, 俊幸","creatorNameLang":"ja"},{"creatorName":"ゴトウ, トシユキ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Gotoh","familyNameLang":"en"},{"familyName":"後藤","familyNameLang":"ja"},{"familyName":"ゴトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Toshiyuki","givenNameLang":"en"},{"givenName":"俊幸","givenNameLang":"ja"},{"givenName":"トシユキ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"8672","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000070162154","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000070162154"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-25"}],"displaytype":"detail","filename":"POF 19_121701-1.pdf","filesize":[{"value":"113.5 kB"}],"format":"application/pdf","license_note":"Copyright (2007) American Institute of Physics.
