In particular I use the known pressure drop to compute the viscous resistance (neglecting the inertial resistance since the regime is laminar in the porous media) but running the simulation I can&#8217;t obtain the right values of pressure drop. Also I don&#8217;t know how to obtain values for porosity with the data I have. The first porous media doesn&#8217;t exchange heat so used porosity equal to 1.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" style=\"font-size: 14pt\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/28-02-2024-1709140008-foto prog.png\" alt=\"\" width=\"845\" height=\"411\"><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-354369","topic","type-topic","status-closed","hentry","topic-tag-fluent-ansys-1","topic-tag-fluent-cfd-ansys-1","topic-tag-heat_exchanger-1","topic-tag-fluent","topic-tag-porosity-1","topic-tag-porous-media","topic-tag-porous-model-1","topic-tag-porous-zone-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["337058","199"],"_bbp_author_ip":["23.218.248.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["922"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["354369"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","337058"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["354528"],"_bbp_last_active_id":["354528"],"_bbp_last_active_time":["2024-02-29 11:52:55"]},"test":"samuele-giugnimail-polimi-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/354369","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\/354369\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=354369"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
