I have a box, with 2 pipes sticking out of it. The two pipes will have ScCO2 coming to the box which has air in it, and mixing.<\/span><\/p>\n<p><\/p>\n<p><span style=\"font-family: 'Open Sans', Arial, Helvetica, sans-serif; font-size: 15px;\">I had typed in a code that I found online into ansys, and it gave me the option to use the NIST, so I selected co2.fld file, then it said that calculations will be performed for the vapour phase. I have selected multiphase, and then Volume of Fluid. I have read someone did a similar study, and they used VOF to simulate the stream of jet that I want too.<\/span><\/p>\n<p><\/p>\n<p><span style=\"font-family: 'Open Sans', Arial, Helvetica, sans-serif; font-size: 15px;\">I have chosen my inlets, my outlets<\/span><\/p>\n<p><\/p>\n<p><span style=\"font-family: 'Open Sans', Arial, Helvetica, sans-serif; font-size: 15px;\">I have two phases, one is air, and other real gas co2 from the refprop etc. The problem is that my box, and the two pipes have 2 phases in the cell zone conditions. But I only need phase 1 (air) in the box, and phase 1 and 2 in the pipes together, because they open to the atmosphere, so air would already be mixed in the pipes I presume, I don&#8217;t expect it to be 100% ScCO2 in the pipes. But if having one phase (ScCO2) in the pipes makes the setup easier, then I am happy with that for the time being.<\/span><\/p>\n","protected":false},"template":"","class_list":["post-39569","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["11748"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1505"],"_bbp_subscription":["245515"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["39569"],"_bbp_forum_id":["27792"],"_bbp_engagement":["22555","171169"],"_bbp_voice_count":["2"],"_bbp_reply_count":["36"],"_bbp_last_reply_id":["101307"],"_bbp_last_active_id":["101307"],"_bbp_last_active_time":["2019-12-20 09:53:29"]},"test":"f123rooq"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/39569","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\/39569\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=39569"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
