The presented \u03b3 transition model is based on the \u03b3 transport equation of the \u03b3-Re\u03b8 transition model. The model is calibrated for external aerodynamic \ufb02ows in a low turbulence environment and is validated based on experimental data for moderate and high Reynolds numbers found in free \ufb02ight. A steady 2D validation case, a steady 3D test case for comparison with the eN method, an unsteady 2D validation test case, and an unsteady 2D test case for comparison with the eN method are presented. In addition, the effect of a boundary layer transition on the \ufb02utter behavior of an airfoil in transonic \ufb02ow at a free \ufb02ight Reynolds number is demonstrated.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/08\/IFASD-2017-066.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Michael Fehrs, Jens Nitzsche, Anne Hebler<b\/><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: IFASD-2017-066<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1953,1964],"tags":[2085,1235,2084],"class_list":["post-17820","post","type-post","status-publish","format-standard","hentry","category-events","category-ifasd-2017","category-steady-unsteady-aerodynamics","tag-airfoil-utter","tag-boundary-layer-transition","tag-local-correlation-based-transition-model","category-993","category-1953","category-1964","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17820","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=17820"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17820\/revisions"}],"predecessor-version":[{"id":17921,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17820\/revisions\/17921"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=17820"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=17820"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=17820"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
