Hello,

I am simulating an Air filter assembly, which has a perforated sheet with 50% opening area and 1.6 mm thick at the outlet.

I can model the perforated sheet as outlet vent BC by providing the loss coefficient as obtained by empirical relations and outlet gauge pressure of 0 Pa.

The other way is to assume the volume of the sheet as a porous media and model the particular volume with the calculated inertial resistance coefficient and the outer face as pressure outlet BC with gauge pressure of 0 Pa.

Are both the approaches correct and can be used?

Help will be appreciated.
