3.1.1. Assumptions

The fluidization behavior of bed particles depended on the forces acting on them. Therefore, this model employed the balance of cohesive and segregate forces to simulate agglomeration/ defluidization and predict the defluidization temperature. Taking account of particle moving, colliding, coalescing, and breaking in a fluidized-bed system, the following assumptions are made to describe the main characteristics of the defluidization phenomena based on the previously described experimental results:
