Although I do get good pressure drop at lower velocities, the drop seems to diverge as velocity increases. I also tried using different turbulence models and they give consistent data among them but they all diverge from experimental data. Any suggestions?<\/p>\n<p>My computational domain is quite simple: a straight pipe with 3 cm of porous medium in the middle. The fluid I am using is water.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/06\/11-06-2023-1686495983-mceclip0.png\" width=\"1073\" height=\"546\"><\/p>\n","protected":false},"template":"","class_list":["post-287989","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["23.206.193.146"],"_bbp_subscription":["17976","15180","199"],"_wp_old_date":["2023-06-09"],"_btv_view_count":["2412"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["287989"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","15180","17976"],"_bbp_voice_count":["3"],"_bbp_reply_count":["20"],"_bbp_last_reply_id":["288943"],"_bbp_last_active_id":["288943"],"_bbp_last_active_time":["2023-06-15 14:10:10"]},"test":"khuzaim-ranawadiaua-pt"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/287989","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\/287989\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=287989"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
