Porous media in FLUENT
 
Hello everyone!

I was simulating a square box with trays as a porous media, where the air is flowing from the inlet passing by the porous media and then go out from the outlet. I only entered the power-law coefficients C0 C1 and the porosity. but then I realised that there is something wrong with it, because I found that in both cases with or without porous media it shows the same results.
Is it wrong to use just the power law model without the inertia and permeability coefficients ?
so I was wondering if someone can help me with this and show me how to simulate a porous media using the power law coefficients.
I'll be so grateful for any comments or answers.
Best regards,
Dounia

Use those coefficients on those boxes right above, on viscous and inertial resistances. Use the same value on all the coordinates, as assuption of isotropic material (which the power law itself implies).

I tried it before, unfortunately, it didn't work. the same result shows each time.
by the way, thank you for answering me I really appreciate it.
Best regards,
Dounia
