High-speed combustion applications, such as ducted rockets, ramjets,<br>scramjet, dual-mode ramjets, and rotating detonation engines, are very interesting propulsion systems,<br>but also challenging to analyze and develop. Up to about a decade ago we were limited to use experimental facilities, equipped with advanced conventional and non-intrusive diagnostic tools to study such<br>flows. The main drawback besides the cost of such studies is the limited field-of-view, and the challenges understanding the whole flow. With the increase in computational capacity seen over the last decade,<br>we now have the possibility of using RANS, LES and DNS to analyze these flows in detail. RANS has been around for a long time, it\u2019s advantages and disadvantages being well known while DNS is only suited<br>for canonical flows due to its very high computational cost. LES on the other hand, have the potential<br>to be used together with experiments to provide detailed insight into the flow physics, and at the same<br>time facilitating various design aspects associated with the flow physics. Here, the concept of LES for<br>high-speed combustion is reviewed, and examples of LES results are discussed.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-258.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-258.pdf\">Read the full paper ><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Christer Fureby<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-258<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1006,1013],"tags":[],"class_list":["post-16203","post","type-post","status-publish","format-standard","hentry","category-events","category-hisst-2022","category-propulsion-systems-and-components-hisst-2022","category-993","category-1006","category-1013","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16203","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=16203"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16203\/revisions"}],"predecessor-version":[{"id":16204,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16203\/revisions\/16204"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16203"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16203"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16203"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
