Supersonic combustion in scramjet engines necessitates rapid fuel-oxidizer mixing and flame stabilization due to the short residence time in the combustor. This study presents findings from experiments conducted using the Pusan National University Direct-Connect Scramjet Combustor (PNU-DCSC) integrated with a Micro-Pulse Detonation Engine. The experimental setup is designed for simulating flight conditions at altitudes of 20~25 km and Mach number 4.0~5.0. The results show that varying the jet-to-freestream momentum flux ratio affects fuel penetration height. Furthermore, as the fuel injection pressure increases, the combustion area expands, leading to transitions in combustion modes and flame structures. The flame-base, where peak combustion pressure forms, moves upstream, and pressure oscillations intensify.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/05\/HiSST-2024-84.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Min-Su KIM, Keon-Hyeong LEE, Eun-Sung LEE, Hyung-Seok HAN, Seung-Min JEONG, Bu-Kyeng SUNG, Jeong-Yeol CHOI<\/b><\/p>\n<p>DOI Number: https:\/\/doi.org\/10.82241\/ceas-hisst-2024-084<\/p>\n<p>Conference number: HiSST-2024-084<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1407,1414],"tags":[1538,1540,1541,1539],"class_list":["post-16799","post","type-post","status-publish","format-standard","hentry","category-events","category-11-hisst-2024","category-propulsion-systems-and-components-11-hisst-2024","tag-cavity-shear-layer-flame","tag-direct-connect-scramjet-combustordcsc","tag-jet-wake-flame","tag-micro-pulse-detonation-engine","category-993","category-1407","category-1414","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16799","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=16799"}],"version-history":[{"count":4,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16799\/revisions"}],"predecessor-version":[{"id":21296,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16799\/revisions\/21296"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16799"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16799"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16799"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
