The water will flow through the pipe and eventually hits the end wall and goes out. I used the k-omega model since the flow is turbulent. I would like to look at the trajectory of the water droplets starting from the inlet. For this, I used the pathlines feature in Ansys Fluent. The problem that I am having is that when I set the starting surface to inlet, there are a number of particles that start from the end wall. I don&#8217;t know where they are coming from and what causes this. Any help is greatly appriciated.<\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" title=\"Geometry model. \" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/07\/05-07-2022-1657011376-pipe flow.JPG\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/07\/05-07-2022-1657011468-pathlines.JPG\" alt=\"\">dThe red pathlines are the ones that start from the inlet and the other ones are what starts from the end wall eventhough I have set the starting surface to inlet.<\/p>\n","protected":false},"template":"","class_list":["post-217702","topic","type-topic","status-closed","hentry","topic-tag-cfd-post","topic-tag-fluid-flow","topic-tag-pathlines","topic-tag-pipe-flow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["259590","199"],"_bbp_author_ip":["204.2.243.141"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["983"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["217702"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","259590"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["217704"],"_bbp_last_active_id":["217704"],"_bbp_last_active_time":["2022-07-05 09:10:32"]},"test":"amirmohammad-rajabiepfl-ch"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/217702","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\/217702\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=217702"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
