It can be seen from velocity plot, the oulet velocity is less as compared velocity at inlet but the dynamic pressure trend is opposite, how is it possible? as the dynamic pressure is a function velocity and density (remians constant through the simualtion).<br \/>In addtion the velocity trends for diferent locations are not matching with the dynamics pressure trend.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/26-04-2023-1682512904-Slide1.jpeg\" alt=\"\" width=\"988\" height=\"556\"><\/p>\n","protected":false},"template":"","class_list":["post-281249","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["66604","199"],"_bbp_author_ip":["23.56.168.190"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["543"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["281249"],"_bbp_forum_id":["27822"],"_bbp_engagement":["199","66604"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["281448"],"_bbp_last_active_id":["281448"],"_bbp_last_active_time":["2023-04-27 13:25:48"]},"test":"chinmayapatraiitkgp-ac-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/281249","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\/281249\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=281249"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
