Currently DLR is involved in several flight<br>experiments, one of which is STORT which focuses on aerothermal loads on hot structures. One essential<br>structure flown on the STORT flight experiment is the fins experiment on the third stage. The fins were<br>investigated both on the vehicle, in windtunnels in Cologne and G\u00f6ttingen but also numerically. For the<br>windtunnel experiment in the HEG (High Enthalpy Shock Tunnel G\u00f6ttingen) the object of investigation is a<br>plate mounted fin which scales 1:2 to the flight hardware. The fin-induced shock boundary layer interaction<br>(SWBLI) on the plate leads to increased thermal loads. The heat flux on the flat plate and fin are investigated<br>using temperature sensitive paints (TSP). For the current study the flow on the plate and around the fin is<br>studied for two HEG freestream conditions at Mach 7.4 using RANS CFD. CFD calculations at both 0 deg<br>AoF and 15 deg AoF were performed and compared for flow topology and turbulence model influence. For 2<br>configurations first preliminary comparisons between experimental and CFD data were conducted. While<br>the XIII freestream condition compares well between experiment and CFD, the XV freestream condition<br>which shows clear signs of transitional flow exhibits rather complex physical phenomena which require<br>further investigation, both experimentally and numerically.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-121.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-121.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Tobias Ecker, Jan Martinez Schramm , Leni Schmidt, Divek Surujhlal, Alexander Wagner<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-121<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1008,1006],"tags":[442,1394,480,1393,1229],"class_list":["post-16485","post","type-post","status-publish","format-standard","hentry","category-high-speed-aerodynamics-and-aerothermodynamics-hisst-2022","category-hisst-2022","tag-cfd","tag-fin","tag-heat-flux","tag-shock","tag-swbli","category-1008","category-1006","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16485","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=16485"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16485\/revisions"}],"predecessor-version":[{"id":16486,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16485\/revisions\/16486"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16485"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16485"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16485"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
