Three cases are compared: typical cold-wall flight, standard wind tunnel conditions, and a third case with enhanced wall cooling to match flight similarity parameters. Global stability and resolvent analyses reveal that wall cooling and higher stagnation temperatures significantly destabilize global modes. While both first and second Mack modes are active in tunnel tests, only the second mode dominates in flight. The third case, with temperature similarity, successfully<br>replicates flight transition mechanisms despite lower stagnation temperatures. These results highlight the crucial role of wall-to-recovery temperature in accurately modeling hypersonic transition and the limitations of conventional ground testing.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/10\/HISST2025_82_paper.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Selwyn VAN DER LAAN, Mathieu LUGRIN, Cl\u00e9ment CAILLAUD, C\u00e9dric CONTENT, Denis SIPP<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: HiSST-2025-082<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,3367,3361],"tags":[440,607,580],"class_list":["post-23038","post","type-post","status-publish","format-standard","hentry","category-events","category-high-speed-aerodynamics-and-aerothermodynamics-with-application-to-hypersonic-regimes","category-1-hisst-2025","tag-hypersonic","tag-stability","tag-transition","category-993","category-3367","category-3361","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/23038","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=23038"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/23038\/revisions"}],"predecessor-version":[{"id":23040,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/23038\/revisions\/23040"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=23038"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=23038"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=23038"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
