The key factors influencing the suppression efficiencies of the solvent-containing water mists were elucidated by measuring the evaporation rates, flash points, extinguishing times, and spray properties (droplet-size distribution, spray mass-flux density, and droplet velocity) of the mists. Suppression trials indicated that (i) heptane pool fires can be extinguished by aqueous solutions of ethanol and 1-propanol at solvent concentrations of 1.0–20.0 vol%, but are not consistently extinguished by the other three solvents, and (ii) the extinguishing times of aqueous ethanol and 1-propanol (despite their high flammability) are significantly shorter than those of a wet chemical (i.e., conventional fire-extinguishing agent). In a stepwise regression analysis, the fire-suppression abilities of water mists containing ethanol and 1-propanol were positively related to the spray flux density, spray velocity, and flash point, enabling an estimation of the extinguishing times. A correlation analysis demonstrated that a faster evaporation rate improves the fire-suppression ability. The results confirmed that ethanol and 1-propanol are effective additives to fire-extinguishing water mists. The study findings provide useful insights into the development of new water-mist fire suppressants, potentially making a large contribution to the reduction of fire-related fatalities and economic losses in industries.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1016/j.jlp.2019.103973","subitem_relation_type_select":"DOI"}}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://doi.org/10.1016/j.jlp.2019.103973"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.jlp.2019.103973","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10860951","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09504230","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Materials Science and Chemical Engineering, Faculty of Engineering, Yokohama National University"},{"subitem_text_value":"Graduate School of Environmental and Information Sciences, Yokohama National University"},{"subitem_text_value":"Department of Safety Management, Faculty of Environmental and Information Sciences, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Koshiba, Yusuke"}],"nameIdentifiers":[{"nameIdentifier":"36325","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamamoto, Yohei"}],"nameIdentifiers":[{"nameIdentifier":"36330","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohtani, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"36331","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":"2021-12-01"}],"displaytype":"detail","filename":"Fire suppression efficiency of water mists containing organic solvents.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Fire suppression efficiency of water mists containing organic solvents.pdf","url":"https://ynu.repo.nii.ac.jp/record/10165/files/Fire suppression efficiency of water mists containing organic solvents.pdf"},"version_id":"f4373b8c-fd24-460c-885d-91483d30716b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fire suppression","subitem_subject_scheme":"Other"},{"subitem_subject":"Water mist containing organic solvent","subitem_subject_scheme":"Other"},{"subitem_subject":"Fire-extinguishing agent","subitem_subject_scheme":"Other"},{"subitem_subject":"Firefighting","subitem_subject_scheme":"Other"},{"subitem_subject":"Additive to water","subitem_subject_scheme":"Other"},{"subitem_subject":"Extinguishing time","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Fire suppression efficiency of water mists containing organic solvents","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fire suppression efficiency of water mists containing organic solvents"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-12-04"},"publish_date":"2019-12-04","publish_status":"0","recid":"10165","relation_version_is_last":true,"title":["Fire suppression efficiency of water mists containing organic solvents"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T18:44:49.612634+00:00"}
