[Mr.choi]

i'm working on revamping current organic silicon FBR at my company. Designing Windbox(portion below distributor) by simulating gas distribution through distributor by Fluent, however, i cannot simulate with the condition which particles are filled in the reactor, which means i'll run it under 'no' particles condition. my question is, "there must be much differences at gas fluidization under the grid when either the particles are filled or not"
i'm just suspicious if it's necessary running this by Fluent. Anyone who can advise me
