摘要: Abstract The hydrodynamic behavior of a cold experimental circulating fluidized bed (CFB) has been investigated using deterministic chaos theory. time series experimentally measured differential pressure fluctuations along the riser height CFB are analyzed. Major frequencies were identified spectral frequency analysis. Poincare maps attractor constructed and correlation dimension measured. appears to be chaotic. fractal this chaotic is found low, ranging from 1.5 1.9, for fluidizing conditions studied.
