There is some information about the cases.ncase 1: VOF method, no surface tension force.ncase 2: Eulerian method, no interfacial force.ncase 3: Eulerian method, default interfacial force(schiller-naumann).nAnd I found that the results of case1 and case3 were similar. So I wonder is there any interfacial force or friction force between gas and liquid when using VOF method. I read the user&#8217;s guide and theory guide, and I didn&#8217;t find the answer. Could you please tell me? Thanks.nGuojunn<\/p>\n","protected":false},"template":"","class_list":["post-50756","topic","type-topic","status-closed","hentry","topic-tag-eulerian","topic-tag-frictional-force","topic-tag-interfacial","topic-tag-vof"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["23008"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["???j"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["330"],"_bbp_subscription":["254104"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["50756"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","179994"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["136723"],"_bbp_last_active_id":["136723"],"_bbp_last_active_time":["2020-12-22 14:01:55"]},"test":"guojun"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50756","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\/50756\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=50756"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
