“…This could lead to improving the prediction of the effective area in structured packing and also to extending the prediction of pressure drop to gas-liquid flow conditions. Second, regarding the upscaling issue, the future development of the two-fluid models with porous medium description (Fourati et al, 2013) will allow identifying the relationship between operating conditions, bed height and maldistribution phenomena on an industrial column scale. Moreover, hydrodynamic simulations using a two-fluid model could be coupled with chemical species transport and reactive absorption modeling.…”

“…A maximum bed height is thus given either in terms of maximum absolute height or in terms of maximum number of theoretical stages per bed (respectively, from 8 m to 12 m or from 10 to 20 stages depending on the packing considered and the vendor); it is sometimes given in terms of the height to diameter ratio. This upscaling issue has recently been addressed with original CFD developments via the integration of liquid phase dispersion modeling (Fourati et al, 2013); however, the simulation tool has not yet been used either for identifying the relationship between operating conditions, bed height and maldistribution phenomena or for design purposes; this would require further work and is thus not further discussed in the present paper. On the contrary, CFD can be used as a design tool for distributing devices, as is discussed in the next paragraph.…”

“…The governing equations of the CFD model deal with average quantities that are volume-averaged over a representative averaging porous volume as shown in Figure. 1 (Fourati et al, 2013). In the present study, incompressible and isothermal flows are considered.…”

“…Trays are still of high importance; CFD application to this type of internal is discussed in Section 3.1. Gas-liquid flow in packings has also been investigated, on different scales either for closure law developments, in particular for liquid-side mass transfer parameters, or for pressure drop determination (Haroun et al, 2010;Petre et al, 2003), for studies on a large scale, in particular for distribution device development and liquid dispersion description Fourati et al, 2013), and even for packing geometry optimisation (Luo S.J. et al, 2008).…”
