Hi all,

I am trying to model the air flow in a torrefaction chamber and I would be glad of any assistance.

This is the Geometry of the Chamber that I am trying to model. As you can see there are two rectangular boxes - one inside the other.
The external box has three circular pressure outlets for the air to be sucked out.
The inner box has a rectangular face at the front, as a velocity inlet for the air to come in.
The top of the inner box has plenty of holes for the air to enter the outer box from the inner box. (Like a zero thickness perforated sheet)

What i want to know is what boundary type do I denote the top of the inner box and the holes as?

Thanks a lot

Your question sounds like you meant to attach a sketch of your geometry, but nothing is there. From your basic description it sounds like you should be using a porous interface boundary condition though. If you provide a sketch or a little more detail you will likely receive more help.
