I'm running a bubbling fluidized bed model using Psuedo 2D CFD-DEM. I have some question about my condition. I want to simulation the 200 micron particle's packed bed in this model which I created by injection file. This file shows the parcel diameter is 2500 micron. I want to set the velocity inlet which calculate based on Archimedes number. What the value of diameter that I must calculate to find the velocity, particle diameter or parcel diameter ?

Using the Archimedes Number, usually particle diameter is used to set the minimum fluidization velocity.
