Phase Change Materials (PCM) Heat Exchanger have been identified as a possible solution to this problem, where the additional heat exchanger would help in reducing peaks in the heat load, extending the lifetime of current technologies. There is a current lack in low computational cost models suited for the initial sizing phase of PCM-Compact Heat Exchanger. An effectiveness-NTU model has been developed that tracks the melting\/solidification front of the PCM by using a linear approximation of the Stefan Condition. Based on an initial loading profile characteristic of aerospace applications, the model was applied to a PCM-Compact Heat Exchanger. Current results are showing good agreement with CFD results and achieve a clear reduction in the simulation time from multiple hours to seconds per loading case, when comparing the model to CFD simulations.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/06\/HiSST-2024-313.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Julie FRANK, Duncan BORMAN, Amirul KHAN, Evaldas GREICIUNAS, Jon SUMMERS<\/b><\/p>\n<p>DOI Number: https:\/\/doi.org\/10.82241\/ceas-hisst-2024-313<\/p>\n<p>Conference number: HiSST-2024-313<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1407,1416],"tags":[1862,1863,1860,1861],"class_list":["post-17270","post","type-post","status-publish","format-standard","hentry","category-events","category-11-hisst-2024","category-thermal-and-energy-management","tag-compact-heat-exchanger","tag-effectiveness-ntu-model","tag-phase-change-materials","tag-thermal-storage","category-993","category-1407","category-1416","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17270","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=17270"}],"version-history":[{"count":4,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17270\/revisions"}],"predecessor-version":[{"id":21220,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17270\/revisions\/21220"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=17270"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=17270"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=17270"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
