This research focuses on a parametric study of three\u00addimensional hydrogen in\u00ad jection in Mach 7.6 and Mach 11.4 flow and subsequent external burning in a wedge geometry using Computational Fluid Dynamics (CFD). The simulations employ detailed 13 species hydrogen\u00adair chem\u00ad istry model. Numerical results are compared to previous experimental study of a wedge\u00adshaped external burning combustor. The performance of the configuration is subsequently assessed by varying the lo\u00ad cation of the injectors along the compression surface of the wedge and the injector fuel pressure. The results suggest that in all simulated cases, the combustion throughout the expansion fan is quenched mainly by the sudden temperature and pressure drop.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/04\/HiSST-2022-433.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/04\/HiSST-2022-433.pdf\">Read the full paper here<\/a>><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b> Matus Cvengros, Quentin Michalski<\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST\u00ad2022-0433 <b><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1006,1013],"tags":[1275,1274,1276,451,614],"class_list":["post-16332","post","type-post","status-publish","format-standard","hentry","category-hisst-2022","category-propulsion-systems-and-components-hisst-2022","tag-external-burning","tag-external-burning-ramjet","tag-hydrogen-injection","tag-ramjet","tag-scramjet","category-1006","category-1013","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16332","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\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=16332"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16332\/revisions"}],"predecessor-version":[{"id":16334,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16332\/revisions\/16334"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16332"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16332"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16332"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
