Numerical simulations using the discrete element method with similar particle assembly model are performed for the surface modification process of thermoset particles. In the simulations, the cohesive force between particles and the effect of thermophoresis are examined numerically in a particle dispersion system. Simulations are also carried out for different gas dispersion velocities. By varying the dimensionless parameter associated with the cohesive force, average agglomerate diameter increases as the cohesive force between particles increases. To the end, it is demonstrated that the cohesive force between particles can be quantitatively determined if the average agglomerate diameter is experimentally or numerically obtained.
