Popis:	In this study, we report the measurement results of various spatial distributions, such as Sauter diameter, gas holdup ratio, and interface area per unit liquid volume, in a vessel using a real-time, high-speed image processing system developed by ourselves. We attempted to separate liquid side mass transfer coefficients, k L , from overall volumetric mass transfer coefficients, k L a, based on the results mentioned above. And we examined the relations between power consumption per unit volume, P v , and both k L and k L a in order to establish correlation equations of k L and k L a with P v , gas holdup ratio, gas superficial velocity, v s , and surface tension.
