Laser intensity fluctuation signals from a bubble column(0.152m ID and 2.5m in height) have been analyzed by resorting to the deterministic chaos theory, to search for the intrinsic order of gas-liquid flow in the column. Some typical chaotic parameters such as Lyapunov exponent and Kolmogorov entropy and attractor in the phase space portrait from the time series of laser intensity fluctuations have been obtained with the variations of operating variables. The attractor which has been constructed with the optimum choice of time lag has been utilized to predict the chaotic behavior of gas-liquid flow in the bubble column. The values of Lyapunov exponent were small but positive; the Kolmogorov entropy increased gradually with an increase in the gas flow rate, however, it exhibited local minimum with the variation of liquid flow rate. It has been found from the results of this study that the dynamic phenomena of gas-liquid contact and flow in the bubble column could be quantified easily. The gas-liquid flow in the column showed the deterministic chaotic behavior in that the Lyapunov exponent and Kolmogorov entropy were finite and positive.
