“…Since the RNG k-e and standard k-w models provide validated results, they are presented as follows. RNG k-e models with near-wall functions were implemented to predict the flow behavior near the wall, as well as the governing rotational flow equations [26,27]. The RNG k-e turbulence model has a good accuracy and is employed with the standard wall function [43,44].…”

“…Thus, a momentum source term is added to the standard fluid equations for the computational cells corresponding to the sheets. The inertial resistance factor, f R , and the permeability, g, which contributes to the viscous loss term, were determined experimentally as discussed by Fernandes et al [26]. The pressure drop was measured inside both an empty tube and tube with a single sheet of the structured packing.…”

“…Fernandes et al [26] proposed a model for the transport phenomena, i.e., single-phase hydrodynamics in structured packing of Sulzer type applied in supercritical fluid extraction. They specified the dry pressure drop in the structured packing by carrying out numerical simulations for two different models with various conditions.…”

Experimental and numerical studies were conducted on the performance and capacity of structured packings for mixture separation with very low separation factor. Different formations and conditions of the innovative structured packing PACK-2100 with high surface area were studied to evaluate the main characteristics such as dry pressure drop. In addition, numerical simulation was performed to describe the details of the flow structure in these modified structured packings. Three-dimensional computational fluid dynamics modeling of PACK-2100 allowed for comparing the pressure drop in both laminar and turbulent flow regime. The obtained experimental and numerical data demonstrate the potential contribution of the packing to high-efficiency systems with low separation factor.

“…Several researchers have used the various turbulence models such as k-e, k-x, RNG and BSL for the gas phase in their simulations [7,12,14,18,19,[29][30][31]. In the present work, the various turbulence models were examined to find an appropriate model for simulation of the flow in the structured packings.…”

“…Using this model, the macroscopic flow field of countercurrent two-phase flow in strongly anisotropic porous structures can be calculated. Fernandes et al [18], using CFD, modeled the dry pressure drop of a module of two packing sheets and partial packing and found reasonable results. In a continuation of their work, they simulated the entire module and calculated the wet pressure drop.…”

Packed columns equipped with structured packings are widely used in separation processes. In this study, the hydrodynamics of MellapakPlus 752.Y was investigated using a computational fluid dynamics (CFD) approach. This packing includes short smooth bends at both ends of each corrugated sheet. Two adjacent sheets of a whole packing module were considered as computational domain. The CFD results indicated that the gas phase should be simulated using a turbulent model for F factors higher than 0.8. Thus, various two-equation turbulence models were evaluated for the gas phase in the CFD model. It was shown that the baseline k-x (BSL) model leads to a slightly improved prediction of the pressure drops compared with the experimental data. The effects of the bends on the structured packing were studied by the model. It was found that using bends in the packings is useful for increasing the capacity and decreasing the pressure drop of the systems.
