To address this, we have developed a DFT\/CFD multiscale<br>framework for the re-entry performance assessment of heat shield materials. firstly , verification was<br>conducted for the use of DFT properties as input parameters for CFD analysis by comparing DFT<br>properties and experimental data. Secondly, the investigation explored high-temperature oxidation<br>mechanisms of UHTCs on different surface orienataitons, employing Ab initio Molecular Dynamics<br>(AIMD) , Density Functional Theory(DFT) simulations This enabled us to perform space environment<br>CFD simulations using DFT properties and obtatined a multiscale understanding of the oxidation<br>performance of re-entry bodies with heat shielding materials.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/05\/HiSST-2024-40.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Jongkyung AN, Seunghwan KWON, Jiseon AHN, Rajkamal ANAND, Gun Jin YUN<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: HiSST-2024-040<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1407,1412],"tags":[1453,1452,1451,529],"class_list":["post-16700","post","type-post","status-publish","format-standard","hentry","category-events","category-11-hisst-2024","category-materials-and-structures-11-hisst-2024","tag-cfdcomputational-fluid-dynamics","tag-dftdensity-functional-theory","tag-multiscale-simulation","tag-re-entry","category-993","category-1407","category-1412","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16700","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=16700"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16700\/revisions"}],"predecessor-version":[{"id":21049,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16700\/revisions\/21049"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16700"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16700"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16700"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
