Paper Title:
DEM Simulation of the Particle Mixing in Spouted Bed of Three Solids Differing in Diameter
  Abstract

In this work, the mixing characteristic of ternary diameter particle system in a rectangular spouted bed was carried out three-dimensional discrete element method (DEM). In particular, the standard k- two-equation model and the Beer & Johnson equation were adopted to investigate the influence of turbulence and rolling friction, and Ashton mixing index was adopted to evaluate the dynamic mixing process of the ternary diameter particle systems. The particle velocity profiles, the gas-solid flow patterns, the particles distribution and the effect of gas velocity on mixing are discussed.
