Please Help."},"content":{"rendered":"<p>Hello,<\/p>\n<p>I am trying to simulate a Gas-Liquid Centrifugal (swirl) Separator. The inlet is located at the bottom of the equipment and the two outlets (one for gas and one for liquid). I am using water (primary phase) and air (secondary phase). The models I activated are Multiphase (Mixture with surface tension) and Viscous (Reynolds Stress). The simulation is transient and it accounts for gravity). the inlet is a velocity-inlet and water and air are at 2 m\/s, graction of air is 0.3. both outlets are pressure-outlets and they are at 0 Pa.&nbsp;<br \/>The issue I am having is that there is REVERSE FLOW. Has anyone simulated this type of equipment and got this same issue, how did you solve this? any kind of help or suggestion is welcome.<\/p>\n","protected":false},"template":"","class_list":["post-307330","topic","type-topic","status-closed","hentry","topic-tag-multiphase_models-1","topic-tag-fluent","topic-tag-mixture","topic-tag-reverse-flow-2","topic-tag-reynolds-stress-model","topic-tag-swirl-flow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["291372","13659","199"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["427"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["307330"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","13659","291372"],"_bbp_voice_count":["3"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["307809"],"_bbp_last_active_id":["307809"],"_bbp_last_active_time":["2023-09-21 07:37:06"]},"test":"laura-osorioou-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/307330","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\/307330\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=307330"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
