On the other hand, negative buoyancy changes in the travel direction in a non-conservative gravity current. The saline thermal belongs to the conservative one. The particle gravity current belongs to the non-conservative one. The objectives of this study are to investigate the flow properties of the conservative inclined thermals by experiments, to obtain the velocity vectors using the image processor, and to compare the experimental results to the numerical ones of velocity fields. Also, the experimental results of the travel speed and the maximum thickness are compared with the numerical ones. The numerical model is based on the k-ε turbulence model and the SIMPLE model to discretize the partial differential equations. Those experimental results are explained by the numerical analysis. Three typical velocity vectors are found out, i.e. the roll up vectors in the front region, the strong vectors in the travel direction and the entrained vectors in the back region.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"3406","nameIdentifierScheme":"WEKO"}],"names":[{"name":"FUKUSHIMA, Yusuke"}]},{"nameIdentifiers":[{"nameIdentifier":"3407","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TAKAGI, Masanori"}]},{"nameIdentifiers":[{"nameIdentifier":"3408","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ENOMOTO, Masato"}]},{"nameIdentifiers":[{"nameIdentifier":"3409","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ETO, Toshihiko"}]}]},"item_4_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長岡技術科学大学"}]},"item_4_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00177120","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0388-5631","subitem_source_identifier_type":"ISSN"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"長岡技術科学大学環境・建設系"},{"subitem_text_value":"ダイナム"},{"subitem_text_value":"中部"},{"subitem_text_value":"長岡技術科学大学エネルギー・環境工学専攻"}]},"item_4_version_type_18":{"attribute_name":"著者版フラグ","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":"福嶋, 祐介"}],"nameIdentifiers":[{"nameIdentifier":"3402","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高木, 正徳"}],"nameIdentifiers":[{"nameIdentifier":"3403","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"榎本, 真人"}],"nameIdentifiers":[{"nameIdentifier":"3404","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"衛藤, 俊彦"}],"nameIdentifiers":[{"nameIdentifier":"3405","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":"2018-08-03"}],"displaytype":"detail","filename":"K24_2.pdf","filesize":[{"value":"346.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"K24_2.pdf","url":"https://nagaokaut.repo.nii.ac.jp/record/703/files/K24_2.pdf"},"version_id":"5bd7ad5b-1944-4f4f-bfbd-6d7f5a258ed5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"conservative inclined thermals","subitem_subject_scheme":"Other"},{"subitem_subject":"k-ε turbulence model","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"image analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"powder snow avalanches","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"保存性傾斜サーマルの流動特性 : 数値解析と画像解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"保存性傾斜サーマルの流動特性 : 数値解析と画像解析"}]},"item_type_id":"4","owner":"2","path":["63"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-02-15"},"publish_date":"2011-02-15","publish_status":"0","recid":"703","relation_version_is_last":true,"title":["保存性傾斜サーマルの流動特性 : 数値解析と画像解析"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T18:43:01.384946+00:00"}
