• 論文の詳細を見る

• Axial mixing of liquid in bubble columns with a counter-current flow is investigated experimentally. Experiments were conducted in vertical columns 0.07 m in diameter and 4.25 m in height, and 0.15 m in diameter and 2.7 m in height. Air and tap water were used as the gas and liquid phases, respectively. The axial dispersion coefficient of liquid increases with increasing gas and liquid velocities, and is discussed by comparing with models based on the turbulent mixing-length theory, which was developed by Matsumoto et al., and on the internal recirculating flow model extended by Wachi et al. in a concurrent bubble column.
