Reply To: Cyclone (Stairmand) simulation using RSM

[Sem B.]

I've done the simulation with a adjusted mesh that resolves the boundary layer (y+<1). At a first sight, this doesn't seem to make much of a difference.

Additionally, I've attempted to setup the DPM for collection efficiency evaluation w.r.t. experimental data. I've noticed that the small particles don't enter the inner vortex (and therefore escape), but they get trapped at the bottom outlet, causing an unrealistic grade efficiency curve. I don't understand why the small particles don't enter the inner vortex.
