Hydrophobic membrane

bryan he · August 12, 2012, 22:04

Hi all,
I'm trying to simulate a hydrophobic membrane using porous media. I get the viscous resistance and inertia resistance by experiments. But after I set the properties of porous media by these data and run case in VOF model, it seems there is liquid(water) in the porous region. It's not hydrophobic.
Does anybody has experience similar to this? Thanks!
Best regards!
Bryan

It seems the porous media doesn't know it should be hydrophobic. How did you try to specify this? I didn't even know there's an option to specify this.
