I would like to simulate a packed bed with random arrangement of particles in heat transfer in CFD-DEM in MFix.
In order to do that, I thought the particles should fall down in presence of gravity to get the packed bed…but how do I put a surface on the top and make sure the particles on the top are touching that surface uniformly?
Is it possible to have moving objects/surfaces, like a cylinder which pushes the particles along the axial direction, packs them and then applies a heat flux?
Would like some guidance on this please.
Thanks.
