I am simulating flow over an airship and I need to locate where the flow transitions from laminar to turbulent flow. To find the point where it transitions, I am plotting velocity profiles at multiple points over the airship using CFD-Post. The velocity profile chart demonstrates that the flow is transitioning from turbulent to laminar, which I think to be inaccurate. I am using the k-&omega; SST transition model and the flow is flowing towards the -x direction.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/440\/CU5222OK22PE.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/440\/CU5222OK22PE.png\" alt=\"pic2.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-168561","topic","type-topic","status-closed","hentry","topic-tag-3d","topic-tag-ansys-student","topic-tag-cfd-post","topic-tag-fluent","topic-tag-fluid-flow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["900"],"_bbp_likes_count":["0"],"_bbp_subscription":["248201"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["168561"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","15977","248201"],"_bbp_voice_count":["3"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["211967"],"_bbp_last_active_id":["211967"],"_bbp_last_active_time":["2022-04-21 10:54:01"]},"test":"ibak-91hotmail-fr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/168561","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\/168561\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=168561"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
