As pointed out by Dryden, the roughness effect proves to be dependent on the ratio of the height k of the roughness element to the displacement thickness δ^*_k of the boundary layer at the element, provided that the transition occurs at a distance from the element. A good correlation of the available data is obtained by plotting the transition Reynolds number Re^*_t based on the displacement thickness as a function of the ratio k/δ^*_k. The presence of a favorable pressure gradient can scarcely alter the relation between Re^*_t and k/δ^_k in the range of variables covered by the present experiment. The effect of free-stream turbulence is conspicuous only at small values of k/δ^*_k, the relation between Re^*_t and k/δ^*_k tending to become a single curve as k/δ^*_k increases.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA1511587000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学理工学研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0371-6090","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162611","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学理工学研究所"},{"subitem_text_value":"東京大学理工学研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"THE INSTITUTE OF SCIENCE AND TECHNOLOGY, UNIVERSITY OF TOKYO"},{"subitem_text_language":"en","subitem_text_value":"THE INSTITUTE OF SCIENCE AND TECHNOLOGY, UNIVERSITY OF TOKYO"},{"subitem_text_language":"en","subitem_text_value":"Department of Chemical Engineering, Tokyo Metropolitan University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"谷, 一郎"}],"nameIdentifiers":[{"nameIdentifier":"419214","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"井内, 松三郎"}],"nameIdentifiers":[{"nameIdentifier":"419215","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山本, 一夫"}],"nameIdentifiers":[{"nameIdentifier":"419216","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TANI, Itiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"419217","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"IUCHI, Matsusaburo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"419218","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YAMAMOTO, Kazuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"419219","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA1511587.pdf","filesize":[{"value":"569.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA1511587.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34289/files/SA1511587.pdf"},"version_id":"44fb6fc7-f160-4931-a0b3-6ed4f2d63248"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Further Experiments on the Effect of a Single Roughness Element on Boundary-Layer Transition","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Further Experiments on the Effect of a Single Roughness Element on Boundary-Layer Transition","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1908"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34289","relation_version_is_last":true,"title":["Further Experiments on the Effect of a Single Roughness Element on Boundary-Layer Transition"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:45:13.415657+00:00"}
