How to simulate a mesh tube acting as a porous fliter?

Please login with a confirmed email address before reporting spam

Hi, I am currently try to simulate a chemical reaction reactor. The figure is attached. The gas flow into the reactor through a tube. This gas tube permit the gas flow inside the reactant region, the gas and the chemical powder react. The tube acts as a porous fliter and permit gas flows in and out , preventing the powder flow out. I want to know how to simulate the mesh tube? The only function of this tube is allowing the gas in and out and preventing the powder out. What physics module or what kind of material character should I add to this region?
