An attempt is made to a new compaction model, which may agree well with experimental result when the particles are very adhesive. In our previous report1), we proposed a new model, in which adhesion force by liquid bridge is considered, for two-dimensional DEM simulations, and the effect of adhesion of particles is found clearly. But in three-dimensional space, particles have more freedoms of movement and it is unable to simulate the movement of particles completely with two-dimensional simulations. In this paper, the simulation model is expanded to three-dimension, and compared with the experimental results. Filling and compaction simulations are carried out in three-dimensional space. In the compaction simulation in the mold with a step, particles are agglomerated and make clusters. The behavior of particles in the compaction process in the mold with a step is also observed with micro-focus X-ray CT system. The behavior of particles observed in the experiment is similar to the simulated results, and the simulated changes of relative density in the higher and lower sections of the mold make a good agreement with the experimental results.
