“…It is based on bubble size classes for the mass balance as well as for the momentum balance. This model has been later on extended by adding a continuous gas phase for a generalized two-phase flow (GENTOP) (Hänsch et al, 2012). The aim of the GENTOP concept is to treat both unresolved and resolved multiphase structures.…”

“…Here, large interfaces may be characterized by sharp gradients of the volume fractions (Hänsch et al, 2012). In order to counteract a numerical smearing of the gradients during the solution of the volume fraction transport equation, certain techniques have to be applied to keep the gradients and hence the interfaces sharp.…”

“…In order to counteract a numerical smearing of the gradients during the solution of the volume fraction transport equation, certain techniques have to be applied to keep the gradients and hence the interfaces sharp. Zwart et al (2003) propose a compressive interpolation technique in the volume fraction continuity equation, whereas Hänsch et al (2012) introduce a clustering force; Strubelj et al, (2009) solve an additional equation, which acts as an artificial compression, right after the solution of the continuity equation.…”

“…Alguns trabalhos pioneiros lidaram com esta questão (Deendarlianto, et al, 2012;Hänsch, et al, 2012;Höhne, 2009;Höhne e Vallée, 2008, 2010. Os modelos consideram um "blending" entre modelos de superfície livre e partículas, e cálculo dinâmico do coeficiente de arrasto com base no módulo da tensão sobre a interface.…”
