Default porosity
Posts: n/a

i have a problem relating to the porosity. how do i define a porous medium in Fluent. the face permeability is not known, how do i calculate it.

the problem is that, the flow occurs through capillaries. the diameter of the capillaries is known. how do i calculate the porosity of the medium to simulate the condition to have a capillary in the model.? requesting suggestions.
