摘要: Deterministic chaos theory offers useful quantitative tools to characterize the non-linear
dynamic behavior of a fluidized bed and the developed complexity theory presents a new
approach to evaluate finite sequences.In this paper, the non-linear, hydrodynamic behavior
of the pressure fluctuation signals in a reactor was discussed by chaos parameters and
complexity measures. Coherent results were achieved by our multi-scale analysis, which
further exposed the behavior in a gas-solid two-phase system.
