Abstract 

In this paper, the phase distribution of gas liquid co-current flow was predicted using computational fluid dynamics (CFD) code FLUENT in structured packing column. The pressure drop and holdup were fitted, and also were verified by experiments. In this paper, the physical model was founded based on packing Mellapak350Y. The RNG k-ε turbulent model was adopted to close the momentum equation. In the calculation, the source term of surface tension and inter phase action were inducted. The simulated results are in good agreement with the experimental data. The comparison show that the method proposed in this paper is successful to solve the gas liquid co-current flow in structured packing column.
