Karman's constant for mesh rough surface flow is lower than that for smooth surface flow, and it decreases with the skewness. The correlation terms between fluctuating velocity and vorticity are constant in the logarithmic region. The value of the correlation between the vertical fluctuating velocity and the spanwise fluctuating vorticity normalized with the wall variable for the mesh rough surface flow with the skewness of -0.847 agrees well with that for the smooth flow. The absolute value of the correlation decreases as the skewness increases. The value of the correlation between spanwise fluctuating velocity and vertical fluctuating vorticity normalized with the wall variables is positive for smooth surface flow, but negative for mesh rough surface flow regardless of the skewness.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"研究分野： 流体工学","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_30001_file22":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"20K04274seika.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://kindai.repo.nii.ac.jp/record/2000347/files/20K04274seika.pdf"},"version_id":"4b0ddf99-c645-4cdf-8b35-68869008703e"}]},"item_30001_funding_reference15":{"attribute_name":"助成情報","attribute_value_mlt":[{"subitem_award_numbers":{"subitem_award_number":"20K04274","subitem_award_uri":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-20K04274/"},"subitem_award_titles":[{"subitem_award_title":"平均渦度輸送方程式に基づく乱流渦構造に対する壁面粗度の影響の解明","subitem_award_title_language":"ja"},{"subitem_award_title":"Effect of wall roughness on turbulent structures based on mean vorticity transport equation","subitem_award_title_language":"en"}],"subitem_funder_names":[{"subitem_funder_name":"独立行政法人日本学術振興会","subitem_funder_name_language":"ja"},{"subitem_funder_name":"Japan Society for the Promotion of Science","subitem_funder_name_language":"en"}]}]},"item_30001_language10":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30001_subject7":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"乱流","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"壁面せん断流","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"PIV","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30001_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"平均渦度輸送方程式に基づく乱流渦構造に対する壁面粗度の影響の解明","subitem_title_language":"ja"},{"subitem_title":"Effect of wall roughness on turbulent structures based on mean vorticity transport equation","subitem_title_language":"en"}]},"item_30001_version_type12":{"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_title":"平均渦度輸送方程式に基づく乱流渦構造に対する壁面粗度の影響の解明","item_type_id":"40001","owner":"42","path":["1697004343623"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-11-08"},"publish_date":"2023-11-08","publish_status":"0","recid":"2000347","relation_version_is_last":true,"title":["平均渦度輸送方程式に基づく乱流渦構造に対する壁面粗度の影響の解明"],"weko_creator_id":"42","weko_shared_id":-1},"updated":"2024-10-23T00:49:22.275694+00:00"}
