title = "EXPERIMENTAL STUDY OF FLUID MOTION AND MASS TRANSFER IN A CYLINDRICAL BUBBLE COLUMN",
abstract = "Flow visualization, particle image velocimetry (PIV) and dissolved oxygen measurement experiments are carried out in a small-scale cylindrical air-water bubble column at different superficial gas velocity. Void fraction profile, total gas holdup, liquid phase velocity fields and volumetric mass transfer coefficient are obtained. Details of each experiment is given, and the result of which is briefly analyzed and compared with simulation result. A new procedure for obtaining a 2D void fraction profile from flow visualization by image processing and proper averaging is introduced, which could provide useful information for CFD model validation. By conducting three sets of experiment related to phase distribution, velocity field and mass transfer in the same apparatus, a validated CFD model for multiphase mass transfer could be established and used in future design of a gaseous fission product removal device.",
