Flow is turbulent. The pipe is embedded inside the sand layer which is heated. I want to see how the water in the pipe will get heated up by the sand layer&#039;s high temperature. But after I modelled it, I get negative temperature (negative values of Kelvin). The sand layer is supposed to be only heated to 55C, so there is no way the temperature can be negative. I am assuming something is not right with my heat transfer because the residual plot for energy starts increasing after sometime and then becomes constant (image attached below).<\/p>\n<p>Any advice is very much appreciated!<\/p>\n<p>Thank you!<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/UU5T3SJCMG5J\/image.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/UU5T3SJCMG5J\/image.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-51788","topic","type-topic","status-closed","hentry","topic-tag-conjugate-heat-transfer","topic-tag-energy-error","topic-tag-fluent","topic-tag-temperature"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["24062"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["+??\u0012"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1890"],"_bbp_subscription":["253866"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["51788"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","22555","179749","184487"],"_bbp_voice_count":["4"],"_bbp_reply_count":["33"],"_bbp_last_reply_id":["141087"],"_bbp_last_active_id":["141087"],"_bbp_last_active_time":["2021-02-03 13:41:05"]},"test":"vsjay3"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/51788","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\/51788\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=51788"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
