摘要：

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