I am giving pressure inlet conditions. Vlume of fluid is used and the fluid(water and ethanol) enters the injector&#8217;s inlet at total guage pressure of 6 MPa&nbsp; and 0 MPa initail guage pressure with operating pressure set to 101325 Pa. What i cannot understand is how my pressure that is achieved is around 7.7 MPa. Because according to my understanding pressure drops when it passes thorugh a constricted region and turbulence is high. The boundary conditions are:<br \/>Top six faces as single pressure inlet with turbulence 10% and hydraulic dia about 5mm<br \/>bottom six faces as single pressure inlet with turbulence 10% and hydraulic dia as 4mm<br \/>The geometry with result is shown below:<br \/><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/04-04-2024-1712207066-mceclip1.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/04-04-2024-1712207066-mceclip1.png\"><\/a> <a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/04-04-2024-1712206973-mceclip0.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/04-04-2024-1712206973-mceclip0.png\"><\/a><\/p>\n","protected":false},"template":"","class_list":["post-360407","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["341574","8124"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["597"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1712297005:292333"],"_bbp_topic_id":["360407"],"_bbp_forum_id":["27792"],"_bbp_engagement":["8124","341574"],"_bbp_voice_count":["2"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["362421"],"_bbp_last_active_id":["362421"],"_bbp_last_active_time":["2024-04-16 09:21:21"]},"test":"mechanicalteamalphagmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/360407","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/360407\/revisions"}],"predecessor-version":[{"id":360425,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/360407\/revisions\/360425"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=360407"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
