Flow simulations of spherical and nonspherical particles were conducted by Cellular Automata method. Cellular Automata method is a class of mathematical systems characterized by discreteness, determinism and local interaction, which was proposed by J. von Neuman and S. Ulam. It is recognized as one of the effective methods to simulate various emergent behavior such as particle flow, biological pattern formation, chemical reaction-diffusion problems, economic growth, etc. In the present paper, several local rules proposed by Baxter et al. and the authors based on physical consideration were used in the simulation of particle flow. The filling process of particles in a hopper, the flow pattern in a hopper and the accumulation behavior on a fiat floor were simulated by Cellular Automata method. An experiment was also conducted using spherical and nonspherical particles, and the simulated results show good agreement with the present experimental results.
