modeling the fluid flow in porous media by Fluent

I need to solve the fluid flow and heat transfer in porous media. my geometry is the simple cavity filled with satureted porous material. i want to solve the free convection in this domain but i have a problem for modeling the porous media and heat transfer by Fluent software. i have a question that: is the answer of fluent in this case reliable.

Provided you specify the momentum sink parameters in accordance with the user's manual, the porous media model works well.

Re: modeling the fluid flow in porous media by Flu

hi please i want to know about the resistances in the porous media in the van Winkle formula in the fluent help didnt write how we can calculate the c for calculation the c2(inertial resistance) please i want to have table or diagram for c also i want to ask is it possible to use porous media for the electrofilter guide plate

Modelling heat flow in porous media in Fluent

Dear all,

I am modelling heat transfer through a porous medium (from hot air to porous medium), have defined porous medium in fluid cell zone, resistance coefficients,
porosity, heat transfer coefficients since i am using non-equilibrium thermal model. this is transient 2D simulation. (a vertical column having porous material inside and top inlet for hot air and bottom outlet).

in start temperature distribution along the domain is fine and close to experimental values, but after 300 or 400 seconds temperature does not change or changes very little at all sections of domain and further it goes below the experimental values. I m using both fluid and solid properties as temperature dependent.
please guide me where i am doing wrong so I am not getting the uniform trend of temperature variation along the domain in whole simulation period.
