The novel spout-fluid bed with multi-ring oblique holes is the specific application of the fluidized bed-chemical vapor deposition (FB-CVD) technique in the particle coating, especially adapted to the preparation of the high-density nuclear fuel coated particles. The modified CFD-DEM numerical simulation platform based on EDEM and FLUENT will be used to simulate the high-density particles fluidization in the complex geometry with strong synergy between holes.

EDEM is a simple-to-use software tool and has a lot of potential.
