Abstract
A preliminary investigation of the scaling laws for bubbling fluidized beds was undertaken using Discrete Element Method simulation. Six 2D and two 3D fluidized beds were simulated and compared using bed snapshots and dynamic pressure drop. Beds properly matched by the simplified criteria were in relatively poor agreement; agreement deteriorated further for a large scale change or a particle density mis-match. Simulations matched by the full scaling criteria agreed well at low velocities but deteriorated at higher velocities. The possible reasons for these results are discussed.
