Effects of bubble Breaking by Floating Material on Pressure Fluctuations in a Continous Bubble Column

Abstract

Effects of floating material on the bubble breaking were inbestigated by analyzing the pressure fluctuations in a bubble column operating continously. The gas and liquid velocites, height from the distributor, and anount of floating material added in the column were selected as experimental variables. The variations of the mean value, standard deviation, skewness, kurtosis and spectral density function from the pressure fluctuations were determined with the variations of experimental variables. From the results of this study, the addition of floating material into the bubble column could improve the qualities of uniformity and stability bubble flowing in the column
