Title: Application of the Kolmogorov Entropy Algorithm for Flow Regime Identification in a Bubble Column

Abstract: The behavior of the Kolmogorov entropy (KE) in a bubble column (0.102 m ID) was studied in order to identify the boundaries of the various flow regimes. The column was equipped with a perforated plate distributor (19 × Æ 1 mm) and was operated batchwise with both ethanol (96 %)-nitrogen and tap water-nitrogen systems at ambient pressure and temperature. The KE algorithm was applied to differential pressure fluctuations recorded at a sampling frequency of 100 Hz. The KE estimation involved the following steps: reconstruction of phase space, plot of chaotic attractor and its characterization by the KE. The KE quantifies the rate of information loss. Based on the peaks in the KE values the boundaries of 4 main regimes were identified. It was found that two of them may be additionally divided into subregimes and their boundaries were also identified by means of the KE algorithm.
