The wall between inner and annulus pipe is required to be modelled. I have created solid zones for LTNE. The boundary conditions at both sides (inner and annulus) wall are attached as pic too. For the two fluids entering at uniform temperatures at their respective inlets, the thermal condition at wall is neither constant temperature not constant flux. So, I want to ask how to give suitable boundary conditions to simulate the heat transfer.<\/p>\n<div data-embedjson=\"{&quot;url&quot;:&quot;\/forum\/wp-content\/uploads\/forum-uploads\/421\/JBUGF2UJA3PP.png&quot;,&quot;name&quot;:&quot;boundary conditions.PNG&quot;,&quot;type&quot;:&quot;image\/png&quot;,&quot;size&quot;:29214,&quot;width&quot;:null,&quot;height&quot;:null,&quot;embedType&quot;:&quot;file&quot;}\">\n<a href=\"\/forum\/wp-content\/uploads\/forum-uploads\/421\/JBUGF2UJA3PP.png\" download aria-label=\"boundary conditions.PNG\"><br \/>\nboundary conditions.PNG<br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-162422","topic","type-topic","status-closed","hentry","topic-tag-2d","topic-tag-ansys-fluent","topic-tag-ansys-workbench","topic-tag-boundary-conditions","topic-tag-cfd"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["585"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["162422"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","223608"],"_bbp_voice_count":["2"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["192692"],"_bbp_last_active_id":["192692"],"_bbp_last_active_time":["2021-09-24 18:42:38"]},"test":"sonika-sharmamech-iitd-ac-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/162422","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/162422\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=162422"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
