Chaotic and fractal analysis of imaging measurements of fluidized bed

摘要

Imaging information indicates chaotic behavior more appropriately than other parameters such as voidage, pressure, temperature etc., since the nonlinear behavior of fluidized bed is caused mainly by bubble's bearing and dying. Result presented in this pa- per confirms this by analyzing the time series of imaging measurements with R/S method of fractal theory construction of chaotic attractor from imaging time series and FFT anal- ysis. Both time series show the same chaotic behavior.
