摘要：The multiphase flow in HiPOxTM reactor are the criteria for the mass transfer of ozone at the gas-liquid interface, determining the degradation rate of the refractory organic pollutant in industrial wastewater. In this work, the gas-liquid flow patterns and their transitions in a static mixer-based HiPOxTM reactor were investigated systematically by a high-speed camera. Six types of flow patterns were identified under the conditions of inlet liquid Re ranging from 8,000 to 160,000 and gas fraction from 3.23% to 86.96%. Three composite flow patterns are involved, and a flow pattern map was demonstrated. The effect of liquid inlet flow rate on the bubble groups is much more significant than that of gas phase in the bub-ble flow. If the liquid flow rate increases twice, the Sauter mean diameter is expected to fall to 65%, which was only reduced by 28% when the gas flow rate even drops 8 times.(c) 2022 Elsevier Ltd.
