Dear all,

I modeled a honeycomb as a porous cell zone condition in a larger model for straighting the flowfield in a confuser.

I had the datasheet for its pressure drop, so I could obtain the inertial and viscous resistance coefficients from its equation. (~1 and ~6.5)

But I dont have any data regarding the two other dimensions.
I use e+08 factor for these directions, but I can see some recirculating zones in the porous media, which is not so realistic.

Have anyone modeled or worked with a honeycomb as a porous zone?
I am looking for the proper order of magnitude for these two other directions, which are normal to the flow direction through the honeycomb.

Thank you in advance!
