Revealing gas-liquid permeable flow phenomena in the porous media is helpful for the environmental impact assessment of geological disposal of radioactive waste and purification of radioactive contamination water. This paper aims to investigate the liquid phase dispersion inside co-current downward gas-liquid flow in the bed packed with spherical particle as basic model. Water and air are injected from the top center of column, and water is spreading to the entire cross-section flowing down along the column. Radial dispersion of water is captured by electrical resistance tomography on several axial positions. The results indicated that liquid flow rate have impact on radial dispersion of water.

AbstractA modified rotating packed contactor was designed and evaluated for the mass transfer of ozone and the ozonation efficiency of 2-chlorophenol under various operational conditions. The rotating packed contactor was composed of an immobilized disc and a rotating packed disc. Both the overall ozone transfer coefficient and decomposition rate of 2-chlorophenol by ozonation process in the modified rotating packed bed were enhanced with increasing rotor speed or decreasing gas/liquid flow rate ratio. The decomposition rate of 2-chlorophenol was accelerated by increasing H
