Recently, the computational fluid dynamics (CFD) method has been introduced as a promising method to facilitate the accurate prediction of airflow and particle behavior in complex geometry. Therefore, this study applied the CFD method to investigate the deposition characteristic of fine particles in the human respiratory tract from the nostrils to the 7th generation. The airflow pattern was simulated using the Eulerian method at breathing flow rates of 7.5 and 30 L/min, and was followed by particle (aerodynamic diameter 1 to 10μm) deposition simulation using the Lagrangian method. In general, the results were comparable with experimental data. The high deposited concentration of particles was found at the 5-7th generation, and a specific deposition hot-spot was observed at the carina ridge."}],"abstractLicenseFlag":"allow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410294407618455937","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Nguyen Dang Khoa"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Interdisciplinary Graduate School of Engineering Sciences, Kyushu University"}]},{"@id":"https://cir.nii.ac.jp/crid/1410294407618455938","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Ito Kazuhide"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Interdisciplinary Graduate School of Engineering Sciences, Kyushu University"}]},{"@id":"https://cir.nii.ac.jp/crid/1410294407618455936","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Nguyen Lu Phuong"}],"jpcoar:affiliationName":[{"@language":"en","@value":"University of Natural Resources and Environment, Ho Chi Minh City"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"24341436"},{"@type":"EISSN","@value":"24341436"}],"prism:publicationName":[{"@language":"en","@value":"Proceedings of International Exchange and Innovation Conference on Engineering & Sciences (IEICES)"}],"dc:publisher":[{"@language":"en","@value":"Interdisciplinary Graduate School of Engineering Sciences, Kyushu University"},{"@language":"ja","@value":"九州大学大学院総合理工学府"}],"prism:publicationDate":"2022-10-20","prism:volume":"8","prism:startingPage":"366","prism:endingPage":"372"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","jpcoar:conferenceName":"International Exchange and Innovation Conference on Engineering & Science(IEICES)","jpcoar:conferencePlace":"九州大学","availableAt":"2022-10-20","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Computational%20fluid%20dynamics%20(CFD)","dc:title":"Computational fluid dynamics (CFD)"},{"@id":"https://cir.nii.ac.jp/all?q=human%20respiratory%20tract","dc:title":"human respiratory tract"},{"@id":"https://cir.nii.ac.jp/all?q=lower%20airway","dc:title":"lower airway"},{"@id":"https://cir.nii.ac.jp/all?q=fine%20particle","dc:title":"fine particle"},{"@id":"https://cir.nii.ac.jp/all?q=deposition%20fraction","dc:title":"deposition fraction"}],"dcterms:subject":[{"subjectScheme":"Other","notation":[{"@language":"en","@value":"Computational fluid dynamics (CFD)"}]},{"subjectScheme":"Other","notation":[{"@language":"en","@value":"human respiratory tract"}]},{"subjectScheme":"Other","notation":[{"@language":"en","@value":"lower airway"}]},{"subjectScheme":"Other","notation":[{"@language":"en","@value":"fine particle"}]},{"subjectScheme":"Other","notation":[{"@language":"en","@value":"deposition fraction"}]}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:2010016014"},{"@type":"IRDB","@value":"oai:irdb.nii.ac.jp:01211:0005644892"},{"@type":"CROSSREF","@value":"10.5109/5909118"},{"@type":"OPENAIRE","@value":"doi_dedup___::cd5329ab7b52ad32a2e0a9540ef7aa5e"}]}
