Permeability for porous body
I have a question about how to set permeability. I have 4 channels with a porous body in between as a cross. I have a value for the permeability of the porous wall but I'm not sure where I can set it.
Under cell zone conditions for the porous body I have used the Power Law model and set the parameters to recieve an pressure drop around 2000 Pa. I have also set the porosity (0.52).
Does anyone know how I should set the permeability for the porous wall?
if you want to set permeability or inertial resistance factors you shouldn't use power law formulation.
note that permeability(m2) is the inverse of viscous resistance(1/m2) in the porous tab.
Thank you very much for your reply Amir, unfortunately I'm do not fully understand how I should proceed. The permeability is the one factor I have a value of and wants to use for my system, how should I do this?
if you inverse permeability value, you'll obtain viscous resistance factor(1/alpha). set that in porous media zone.
if you want to use this procedure (setting permeability directly) do not activate alternative formulation.
