Porous media modelling vs outlet vent BC

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. |
