I choose Eulerian -Eulerian model with water as primary phase and vapor as secondary phase. Vapor will flow inside the core of tube and liquid as film at wall. Moreover, I am using DPM to inject liquid droplet from the interior_surface(please see attached mesh). Will this interior surface create blockage to flow liquid\/vapor in tube?<\/p>\n<p>2) Only vapor is flowing from the inlet (keep the volume fraction 0 under multiphase tab, if I keep 0 here I am getting residuals for water and for 1 ,getting residuals for vapor only) and I am using a injection wall (EWF) near inlet for liquid film. Here I have added a mass flux(water)<\/p>\n<p>3) I enable Eulerian Wall Film at injection wall, stabilization and annular wall under boundary conditions and finally initialize EWF from Model(Eulerian Wall Film)<\/p>\n<p>The simulation is running but giving residuals only for water or vapor ,not water and vapor together.<\/p>\n<p>Would you tell me where is the mistake?<\/p>\n<p><\/p>\n<\/p>\n<p>Thank You<\/p>\n<p>Anadi<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/8XWRRNR1NWJN\/an-jpg.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/8XWRRNR1NWJN\/an-jpg.jpg\" alt=\"an.JPG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-53263","topic","type-topic","status-closed","hentry","topic-tag-ansys-fluent","topic-tag-fluid-dynamics","topic-tag-fluid-flow","topic-tag-multiphase","topic-tag-udf-fluent"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["25575"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["\u0018?3v"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["4217"],"_bbp_subscription":["232243"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["53263"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","185601"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["146446"],"_bbp_last_active_id":["146446"],"_bbp_last_active_time":["2021-03-15 15:26:03"]},"test":"anadi"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/53263","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\/53263\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=53263"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
