But I have a problem with Outlet boundary conditions. As a result of the simulation, when the flow passes through the throat of the air intake, it slows down as expected due to the oblique shocks and decreases to subsonic speeds. But the problem is that as the flow moves towards the outlet, it speeds up again and reaches supersonic speeds. Everything I tried to prevent this was unsuccessful. No matter how much I changed the Outlet Back Pressure, the result was still the same. <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/878\/BICI7URH3O2E.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/878\/BICI7URH3O2E.png\" alt=\"mach number.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-166133","topic","type-topic","status-closed","hentry","topic-tag-cfd","topic-tag-inlet","topic-tag-intake-1","topic-tag-supersonic-flow-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["734"],"_bbp_likes_count":["0"],"_bbp_subscription":["247484"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["166133"],"_bbp_forum_id":["27792"],"_bbp_engagement":["118","247484"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["204612"],"_bbp_last_active_id":["204612"],"_bbp_last_active_time":["2022-02-07 15:23:54"]},"test":"bicakcibarishotmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/166133","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\/166133\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=166133"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
