This method<br>is characterized with high-level fidelity numerical analysis of external flow and low-level fidelity<br>numerical analysis of internal flow. The external flow of propulsion system are solved by RANS equations.<br>The internal flow is modeled by quasi-one dimensional equation. The interaction between external and<br>interflow is governed by the CFD solver through user-defined function. The static pressure distribution<br>acquired from multi-fidelity simulation method agrees well with the experimental data, indicating that<br>this simulation method can be used to study the flow physics in hypersonic propulsion system at a<br>reasonable cost. The results from design point indicate that the horizontal force increases with fuel<br>equivalence ratio and the thrust balance is realized at \u03c6=0.35. The positive net thrust is maintained<br>throughout the flight regime from Ma 4 to Ma7 whether the combustor operates in ramjet or scramjet<br>mode.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-436.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-436.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Jun Liu, Huacheng Yuan, Jinsheng Zhang, Zheng Kuang<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-436<\/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":[1363,1364,1365,1362],"class_list":["post-16457","post","type-post","status-publish","format-standard","hentry","category-hisst-2022","category-propulsion-systems-and-components-hisst-2022","tag-external-and-internal-flow","tag-hypersonic-air-breathing-propulsion-system","tag-multi-fidelity-simulation-method","tag-quasi-one-dimensional-model","category-1006","category-1013","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16457","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=16457"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16457\/revisions"}],"predecessor-version":[{"id":16458,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16457\/revisions\/16458"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16457"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16457"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16457"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
