 November 8, 2007, 20:56 spercritical fluid flow in porous media #1 cachen Guest   Posts: n/a dear all: Do you have experience to simulated supercritical fluid or porous media? How to set up for supercritical fluid in FLUENT? And in fluent user's guide, it didn't wrote detail momentum equation for porous media. If i turn porous zone on,Which form of momentum equation in porous media will use in FLUENT? My study is to combine this two in FLUENT. Can FLUENT do it? Help me out, please. best regard cachen

I hope it help Best Regards Chandra Manik

I know that it added two source terms for momentum equation, but i did not know it will change the form of momentum equation in porous media or not. In literature of porous media, every terms in momentum equation will have porosity effect like this equation in below link http://www.me.ncu.edu.tw/fluent/flowmen/porous.pdf so, i am confused this equation with FLUENT user's guide which only add two terms. Can someone explain it? Thanks very much. Best regard cachen
