Hi guys

I'm at a degree work in a ingeneer's school.

My work based on the topic "airflow through a porous zone".

I am working with porousSimplefoam and put there the darcy number in. But actually I cannot comprehend which formula is behind the darcy number.

Can you explain that?

Thanks for the help,

hunzs2
