OK, so with that volume fraction DPM is OK. There's then whether you need to model the mass transfer, or just show a good particle distribution. The trick with CFD is to know how little you can do to answer the question that's been posed. Also whether the mass transfer is condensation or absorption as there's a difference in what else you need to think about. Do particle saturate? Lots to consider before getting to the solver.
