CFD Analysis of two-phase pressure drop in structured pakings

In structured packings, the pressure drop is one of the critical factors in calculating the optimal diameter of the tower. In the present research, two phase pressure drop in SulzerBX structured packing was optaincd by computational fluid dynamics and compared with experimental data. The relative error was 9.1%. Furthermore, the amount of maximum pressure drop was 833.7 Pascal per meter at gas and liquid velocities of 0.899 and 0.0298 m/s, respectively. In addition, the minimum pressure drop was 25.1 Pascal per meter at gas and liquid velocities of 0.341 and 0.0298, respectively. Compared with conventional packings the pressure drop in perforated plates illustrated a 7% reduction. This study aims to investigate the influence of packing plates holes on two phase pressure drop.
