Abstract:
Compartmentalized bidisperse granular gases are numerically studied. Molecular-dynamics simulations studying granular clock phenomenon in three dimensions are presented, which complement previously reported two-dimensional simulation results. A flux model for binary mixtures is found to give qualitative descriptions for the oscillations, with no undetermined parameters or functions. Two different states, a degenerate oscillatory state and a state with large particles segregated and small particles homogeneously distributed, are found in our simulations. These features reveal a much more complex phase diagram for the system, which challenges the existing theoretical models.
