Basically, the water flows through the pipe and hits an end wall and eventually goes through the outlet. Choosing the right turbulence model has become a bit of a delimma for me since I get different results depending on which model I use. Based on what I have read, SST k-omega model seems to better fit internal flow and flows that deal with fluid-wall interaction. I would like to know the insight of the community that has more experience with these models. Is the SST k-omega the better choice in this case?<\/p>\n<p>I have also attached a photo of the geometry.<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/07\/06-07-2022-1657093860-pipe flow.JPG\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-217810","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["259590","199","22555"],"_bbp_author_ip":["204.2.243.141"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["4646"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["217810"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","22555","259590"],"_bbp_voice_count":["3"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["219018"],"_bbp_last_active_id":["219018"],"_bbp_last_active_time":["2022-07-19 18:05:08"]},"test":"amirmohammad-rajabiepfl-ch"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/217810","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\/217810\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=217810"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
