Dany Rincon Guest Posts: n/a	Hello I am designing a settling chamber, and i need to simulate the flow of air through a honeycomb and screens in FLUENT. I want to know if i should take the honeycomb as a porous jump or porous media (it is 76 mm long) and i don't understand very well what is the permeability in the porous jump inputs, in the user guide help talks about the Blake-Kozeny equation but it applies for porosity of less than 50% and my screens are above 65%, and i don't know what the particle diameter refers to. I am asuuming that the medium thickness is the wire diameter. Please, i appreciate any help Thankyou for your time
