摘要：

For gas-liquid bubble column with dense vertical bundle internals, the resistance force of bundles on gas and liquid phases was taken into account in the two-phase Euler axisymmetric k-Ε model. By introduction of corresponding momentum source, turbulence source and dissipation source, a 2-D CFD model of bubble column with bundle internals was established. The model could clearly and accurately demonstrate the features of gas-liquid flow in bubble column with bundles: funnel effect and extension of sparger zone. The calculated two-dimensional distributions of hold-up and liquid velocity agreed with experimental data within a wide range of superficial gas velocity (0.12-0.62 m·s-1). ©, 2015, Chemical Industry Press.
