Phys. Rev. E 57, 1990–1996 (1998)Analysis of statistical quantities in simulation of fluidized bedsReceived 28 April 1997; revised 29 August 1997; published in the issue dated February 1998 Systematic simulations are carried out based on the model of fluidized beds proposed by the present authors [Phys. Rev. E 52, 658 (1995)]. In our simulation of monolayer particles, the transition of fluidization is a continuous transition. Two types of fluidized phases, the channeling phase and the bubbling phase, are observed. Our simulation suggests that the flow rate plays the role of the effective temperature and the process generating free volume is important for time-averaged statistical quantities. The flow-rate dependence of the diffusion constant suggests the existence of a kind of fluctuation-dissipation relation. © 1998 The American Physical Society URL:
