It works fine without the energy equation, but I get strange temperatures when energy is enabled (I need energy on).<\/p>\n<p>The whole domain is initialized at 300 K, pressure inlets\/outlets have 300 K specified, and walls have 0 heat flux. Yet, as evaporation occurs, the temperatures near the location of mass transfer start to drop. It starts small, but usually builds to divergence, where I get the &#8220;Temperature limited to&#8230;&#8221; error. These low temperatures actually start to follow the vapor phase as is progresses (see images).<\/p>\n<p>I could understand some evaporative cooling taking place, but I don&#8217;t think that&#8217;s what this is (it occurs far too fast, and shows reduced temperatures in the vapor, rather than the liquid).<\/p>\n<p>Images below &#8211; Thanks in advance for any suggestions.<\/p>\n<p><img decoding=\"async\" title=\"Steam concentration\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/12-04-2023-1681325289-Screen Shot 2023-04-12 at 1.39.16 PM.png\" alt=\"Steam concentration\"><img decoding=\"async\" title=\"Temperature\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/12-04-2023-1681325307-Screen Shot 2023-04-12 at 1.39.06 PM.png\" alt=\"Temperature\"><\/p>\n","protected":false},"template":"","class_list":["post-279146","topic","type-topic","status-closed","hentry","topic-tag-multiphase_models-1","topic-tag-evaporation","topic-tag-fluent","topic-tag-species"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["22325","199"],"_bbp_author_ip":["23.56.168.214"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["880"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["279146"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","22325"],"_bbp_voice_count":["2"],"_bbp_reply_count":["15"],"_bbp_last_reply_id":["280092"],"_bbp_last_active_id":["280092"],"_bbp_last_active_time":["2023-04-18 13:57:25"]},"test":"caratenuto-anortheastern-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/279146","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\/279146\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=279146"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
