Ablation timescales are orders of magnitudes larger than flow time scales,<br>making computational modelling of ablation problems only feasible if ablation is artificially sped-up.<br>First, a subliming sphere at Mach 4 is investigated. It is found, that if the speed-up factor is small<br>enough then the shape change due to ablation is independent of the speed-up factor. Then, a novel<br>test case with a backward facing step with binary species ablating boundary under transitional flow<br>conditions is created and investigated. Roughness is found to develop due to differential ablation and<br>causes uneven surface recession, this promotes the generation of vorticity in the boundary layer. Crosshatching ablation patterns are not observed in the current simulations, however, long-time simulations<br>of the current case may lead to such patterns.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-364.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-364.pdf\">Read the full paper ><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Monal Patel and Salvador Navarro-Martinez<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-364<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1008,1006],"tags":[872,1215,1214,440,1216,1217],"class_list":["post-16246","post","type-post","status-publish","format-standard","hentry","category-events","category-high-speed-aerodynamics-and-aerothermodynamics-hisst-2022","category-hisst-2022","tag-ablation","tag-adaptive-mesh-refinement","tag-fluid-structure-interaction","tag-hypersonic","tag-immersed-boundary-method","tag-moving-boundaries","category-993","category-1008","category-1006","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16246","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\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=16246"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16246\/revisions"}],"predecessor-version":[{"id":16247,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16246\/revisions\/16247"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16246"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16246"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16246"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
