“…Moreover, this method allows for estimating the influence of diverse factors. Numerous researchers tried to develop an effective computational scheme, containing accurate discretization methods and solution algorithms, to propose a precise model for simulating the flow in the packings, and a number of codes and softwares were proposed [39][40][41][42][43][44][45][46].…”

The novel wire gauze structured packing, PACK‐860, was characterized by means of numerical methods. The main features of PACK‐860 such as height equivalent to a theoretical plate (HETP) and dry/wet pressure drop were evaluated. The flow structure in this packing was described by numerical simulation. To estimate the amount of HETP and dry/wet pressure drop, three‐dimensional computational fluid dynamics (3D CFD) modeling with the Eulerian‐Eulerian multiphase approach was applied. The average relative errors between the results obtained from CFD simulation and experimental findings for mass transfer efficiency and wet and dry pressure drop were assessed. Numerical observations were found to agree well with the empirical results, proving the reliability of CFD simulations for modeling separation processes.

“…The turbulence model is applied to achieve high-accuracy results due to the complexity of the flow characteristics inside the structured packing. According to the preceding studies, the proper turbulence model is the two-equation model of the standard k-w model introduced by Wilcox [49] and elaborated by other authors [50][51][52][53][54][55].…”

The novel wire gauze structured packing PACK-1300Y with high specific surface area was characterized by computational fluid dynamics. The main features of PACK-1300Y were investigated including the dry and wet pressure drop as well as the height equivalent to a theoretical plate (HETP). Moreover, the flow structure of this packing was described via numerical simulations. To evaluate the amount of HETP and dry and wet pressure drop, 3D computational fluid dynamic modeling with respect to the Eulerian-Eulerian multiphase approach was applied. The average relative errors were determined between the findings achieved from computational fluid dynamic simulation and experimental findings for mass transfer efficiency and wet and dry pressure drop, respectively.

“…Comprehensive effort was spent to momentum and mass transport properties including liquid holdup, flow regime, twophase mass transfer coefficients, and pressure drop of structured packings [57][58][59][60][61][62][63][64]. Several geometry designs and parameter studies were applied to develop the performance of the packings.…”

Structured packings are usually employed for increasing the surface contact between vapor and liquid in the absorber and distillation of columns. Experimental investigations are performed to present a high-capacity new wire gauze-structured packing, namely, PACK-1300XY, which is the combination of PACK-1300X and PACK-1300Y. The new PACK-1300XY shows improved efficiency of separation and pressure drop. Comprehensive parametric investigations are carried out to calculate the efficiency of mass transfer and the wet/dry pressure drops under different operating conditions. The new wire gauze-structured packing reduces wet and dry pressure drops by more than 10 % in comparison to PACK-1300Y. In addition, PACK-1300XY decreases the height equivalent to a theoretical plate by more than 5 % compared to PACK-1300X.
