The regenerative cooled nozzle present in the historic configuration is eliminated from the system and replaced with several small er nozzles shaped inside each core&#8217;s coolant channels. The focus of this study is the determination of the channel&#8217;s optimum geometry for a general fuel element and the corresponding power density distribution. These outputs are achieved by implementing a new methodology for solving the ID steady viscous and non-adiabatic duct flow equations by imposing the Mach number and the wall outer temperature profiles as boundary conditions.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.eucass.eu\/doi\/EUCASS2023-042.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>ELIA PUCCINELLI; ANGELO PASINI<\/b><\/p>\n<p>DOI Number: 10.13009\/EUCASS2023-042<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3766,993,3784],"tags":[3898,3899,3900,3901],"class_list":["post-25533","post","type-post","status-publish","format-standard","hentry","category-1-aerospace-europe-conference-2023","category-events","category-18-testing-in-aerospace","tag-1d-gasdynamic","tag-non-adiabatic-flow","tag-nuclear-propulsion","tag-viscous-flow","category-3766","category-993","category-3784","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/25533","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=25533"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/25533\/revisions"}],"predecessor-version":[{"id":25534,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/25533\/revisions\/25534"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=25533"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=25533"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=25533"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
