A series of wind tunnel experiments were conducted on a 270 mm long flared cone model at Mach 5 in the High-Supersonic Tunnel (HSST) at University of Manchester. Herringbone riblets, produced via laser manufacturing techniques, were evaluated for their influence on boundary layer transition, using high-speed schlieren imaging. The effects of riblet height and placement along the model were systematically examined. It was found that riblets with a height of 54 \u00b5m placed at 170\u202fmm from the leading edge of the model delayed the onset of transition at a unit Reynolds number of Reunit = 10 \u00d7106 m\u22121, demonstrating their potential as a means of effective flow control in hypersonic flow.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/10\/HISST2025_343_paper.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Wenkai ZHU, Shan ZHONG, Johan STEELANT<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: HiSST-2025-343<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,3361,3370],"tags":[3393,3392],"class_list":["post-22431","post","type-post","status-publish","format-standard","hentry","category-events","category-1-hisst-2025","category-hypersonic-fundamentals-history","tag-herringbone-riblets","tag-hypersonic-boundary-layer-transition","category-993","category-3361","category-3370","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/22431","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=22431"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/22431\/revisions"}],"predecessor-version":[{"id":22433,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/22431\/revisions\/22433"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=22431"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=22431"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=22431"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
