I did everything you specified above I only have two clarifications:confused:. 1.) I sometime get a negative k=permeability because when I plot DeltaP vs Velocity it gives me an equation with a Bx. My question is, can I use this () Value of k as input? if not please give me a hint on how to remedy this problem.:D 2.) To get C2 and k you have to use L=Thickness. My question is what thickness to use?, the thickness of the screen which you got the experimental data from ,(P vs V), or the representative porous media's thickness used in the solver (I some times use thick Porous media for ease of meshing):p Thanks.:) will:cool: 
Details of Porous Media
Hello,
I am trying to understand and operate a porous media in which the void fraction is arranged in random order. Whenever I select the system as laminar, the flow is laminar and even when I select it to be turbulent, the flow is laminar. So, what are the factors we need to consider (it is very complicated to consider all points) to simulate the random arrangement of the void fraction? Further which parameters are normally selected and avoided while considering the porous media. 
porous media
hi for all
I need to know the steps of build up a porous media by using fluent program I need for these steps too much so I wish form any one who can present the assistance to support me please 
Hi every body
I don't know how determine initial velocity for the flow in porous media. Thank you for time and consideration. Best regards 
Hello Rupak Banerji,
In your first message you said about tutorial number 8. Which series of tutorial you are solving? can you share? 
modelling porous surface
Hey friends
how do i model a porous surface in ansys fluent? can i make a wall surface porous need help thanks in advance

hi Nelly.
you said that pressure drop can be calculated from CFD. I am working on combustion of heptane gas through porous medium. In this case how can i calculate the porous coefficient. Your help is really needed. 
Porous media
The Velocity in porous media shows the same as inlet pipe. Is their any difference in velocity in porous media and the velocity in empty pipe??

Porous media
Is their velocity difference in porous media and the empty pipe. I doing simulation in ansys. Using physical velocity but i didnt se the difference in velocity
