Three<br>fuelling configurations were evaluated using a combination of injector ports located upstream, downstream, between, and within the tandem cavities \u00ad maintaining a consistent fuel\u00adto\u00adair equivalence ratio<br>at 50% of stoichiometric. Combustion behaviour was compared between \u2018cold\u00adwall\u2019 conditions, representing shock tunnel equivalent test conditions with minimal wall heating, and \u2018hot\u00adwall\u2019 conditions,<br>representing steady, in\u00adfight wall temperatures. Under hot\u00adwall conditions, a portion of the wall boundary represented a thermal sink for regenerative fuel heating. Mixing, fuel penetration, and total heat<br>release were highest for the upstream\u00adonly (baseline) fuelling configuration, however the distributed<br>fuelling schemes presented resulted in up to 29% less drag at the expense of a 9% reduction in total<br>heat release. Distributed fuelling methods external to the cavity were more robust to changes in the<br>thermal environment.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-448.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-448.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Sarah Mecklem, Damian Curran, Will Landsberg, Ananthanarayanan Veeraragavan<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-448<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1006,1013],"tags":[712,546,614,1378],"class_list":["post-16471","post","type-post","status-publish","format-standard","hentry","category-hisst-2022","category-propulsion-systems-and-components-hisst-2022","tag-combustion","tag-hypersonics","tag-scramjet","tag-tandem-cavity","category-1006","category-1013","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16471","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=16471"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16471\/revisions"}],"predecessor-version":[{"id":16472,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16471\/revisions\/16472"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16471"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16471"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16471"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
