Interfacial area density in porous media

Hi everybody!

How Can I calculate interfacial area density in porous domain?

Hi, did you find how calculate this?

the specific surface area (surface per unit volume) a_fs is given by
a_fs =6(1- $\epsilon$ )/d_p
where dp is the particle diameter.

dpore=dparticle [(1-e)^(-1/3) -1]

e is porosity

reaction model?"

Just read some of your replies, contesting.

I have a cloth which allows air through and some droplets. Entered the figure 0.09 for volume porosity, as shown in attached screenshot. Don't know how to fill out the following: -
Interfacial Area Den?
Permeability left it out for now.

Air carrying 0.1 microns water droplets pass through cloth.

Thanks.
