hi :
I have a question for your help:
my model is a homogeneous porous granule in an infinit fluid field. i know the porosity of the granule but i don't know the permeability. i want to know when the granule move in the fluid, how much fluid can flow through it, so this means i want to know the permeability. but i read the help maybe it can define the permeability in fluent, and i don' know the C0 and C1 means, does it has something to do with the permeability? and does the fluent use default model for porous media? what about the carman-kozeny model?
so i am puzzled, can i only use the porosity to calculate the model and estimate the permeability?or can i use the C0 and C1 to define my permeability in fluent?
thank you very much!

Hi,
You can use Kozeny Carman model to calculate permeabilities, as a good approximation.

See my earlier reply in this forum regarding permeabilities:
