For backed bed catalyst zone, I am using porous model. I have a confusion with the modelling approach of porous media. There are two approaches present in FLUENT, physical and superficial velocity.<\/p>\n<p>When I have compared the transport equation involving porous effect present in the reference paper to that of FLUENT theory guide, there are some deviations in it. This is shown in the attached image.<\/p>\n<p>Also, I am getting deviations in velocity and pressure contours when compared my simulation to that of reference paper. I am thinking this is due to this porous modelling approach.<\/p>\n<p>Please guide me about which approach should I use?<\/p>\n<p>Anshul<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/PY46HLHURTV8\/model-doubt.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/PY46HLHURTV8\/model-doubt.png\" alt=\"model doubt.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-52302","topic","type-topic","status-closed","hentry","topic-tag-chemical-reaction","topic-tag-fluent","topic-tag-porous","topic-tag-porous-media"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["24588"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["\u000e?\"\u0005"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1266"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["52302"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","184487","185723"],"_bbp_voice_count":["3"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["142720"],"_bbp_last_active_id":["142720"],"_bbp_last_active_time":["2021-02-17 16:21:43"]},"test":"anshul"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/52302","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\/52302\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=52302"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
