“…In recent years, the VOF CFD approach has been used more and more to investigate wetting, the effective area and liquid hold-up in structured packing (Ataki and Bart, 2006;Hoffmann et al, 2006;Shojaee et al, 2011;Haroun et al, 2014;Sebastia-Saez et al, 2013;Iso et al, 2013;Iso and Chen, 2011). Indeed, this method is adapted to simulate wetting phenomena since it is possible to specify a wall adhesion angle in conjunction with the surface tension model (Raynal et al, 2009).…”

-Computational Fluid Dynamics (CFD) is today commonly used in a wide variety of process industries and disciplines for the development of innovative technologies. The present article aims to show how CFD can be used as an effective analysis and design tool for the development and design of packed gas/liquid absorption columns. It is first shown how CFD can be used for the characterisation of packings. The different hydrodynamic and mass transfer design parameters are investigated and adapted CFD methods are suggested. Secondly, column distribution internal development is discussed to show how CFD simulations should be performed to improve the design of gas and liquid distributors. An example of the development of new distribution technologies for floating installation of a reactive absorption column is also presented.Résumé -Utilisation de la dynamique des fluides numérique pour le design des colonnes d'absorption à garnissages -La dynamique des fluides numérique (Computational Fluid Dynamics, CFD) est aujourd'hui couramment utilisée pour le développement de technologies innovantes dans de nombreux domaines et procédés industriels. Cet article a pour objectif de montrer comment la CFD peut être utilisée comme outil d'analyse et de dimensionnement pour le développement des colonnes d'absorption gaz-liquide à garnissages. En premier, il est présenté comment la CFD peut être utilisée pour caractériser les différents paramètres de dimensionnement d'un garnissage (hydrodynamique et transfert). Les méthodes CFD appropriées sont suggérées et discutées. En second, l'utilisation de la CFD pour le développement et l'optimisation des internes de distribution gaz-liquide est exposée. Un exemple de développement par CFD d'une nouvelle technologie de distribution pour une colonne d'absorption réactive sur une installation flottante offshore est présenté.

Modelling of the hydrodynamics behaviour of the liquid on the corrugated sheets of packing is studied using three-dimensional, volume-of-fluid (VOF) model that is incorporated in Ansys Fluent 12.0. The flow of three different liquids with different physical properties is modelled. A domain of corrugated sheets of packing resembling the real structured packing with little modifications in the elementary geometry is constructed using ICEM CFD 12.0. The quantitative comparisons of the wetting behavior from the simulations are in good agreement with experiments. Further, the study has been extended to understand the influence of the second corrugated sheet on the flow behavior. The contours from the simulations indicate the liquid hold-up in the crimp of two corrugated sheets, and these results are in good agreement with the earlier experimental studies performed using X-ray tomography in the literature. The result from the simulation shows that even for the high flow rate of around 811 mL/min for silicon-oil (DC5), only 60% of the corrugated sheet has been wetted. Hence, the efficiency of the existing packing can be further increased by increasing the wetted area in the corrugated sheet of packing.

“…While another one was a fluorescence intensity method, which allowed the simultaneous measurements of film thickness and wave velocity. In order to investigate the behavior of multiphase flow on inclined plates, Hoffmann et al [16] have used a particle image velocimetry (PIV) method to measure the flow surface velocity. They used a stroboscope that allowed double exposures of the pictures of the tracers.…”

Characteristics of film flow during transition to three-dimensional wave regimes A Bobylev, V Guzanov, A Kvon et al. Abstract. Falling liquid films on inclined wall present in many industrial processes such as in food processing, seawater desalination and electronic devices manufacturing industries. In order to ensure an optimal efficiency of the operation in these industries, a fundamental study on the interfacial flow profiles of the liquid film is of great importance. However, it is generally difficult to experimentally predict the interfacial profiles of liquid film flow on inclined wall due to the instable wavy flow that usually formed on the liquid film surface. In this paper, the liquid film surface velocity was measured by using a non-intrusive technique called as photochromic dye marking method. This technique utilizes the color change of liquid containing the photochromic dye when exposed to the UV light source. The movement of liquid film surface marked by the UV light was analyzed together with the wave passing over the liquid. As a result, the liquid film surface was found to slightly shrink its gradual movement when approached by the wave before gradually move again after the intersection with the wave.
