An arbitrary Lagrangian–Eulerian method for simulating bubble growth in polymer foaming

A coupled volume-of-fluid/level-set method for simulation of two-phase flows on unstructured meshes

“…Fig. 21 illustrates a comparison of the bubble shape and wake structure based on the present VOF/LS method, against experiment of [21], and other interface capturing methods, including the body-fitted method [35], ALE approach [37] and VOF approach [14]. Indeed, present result is in close agreement with experiment of [21], and other numerical studies from the literature.…”

Structuring of indirectly expanded snacks based on potato ingredients: A review

“…Bubble rupture has hardly been investigated. There is one study concerning the physics of bubble rupture in synthetic polymers (Taki et al, 2006;Yue et al, 2007). For viscoelastic polymer matrices the bubble rupture can be predicted using the Considere criterion for instability in extension for polymers.…”

Selective withdrawal of polymer solutions: Computations

“…We have adopted a sharp-interface formulation that deploys grid points directly on the interface, and tracks their motion as a result of the fluid flow and stresses. Our numerical code is based on an arbitrary Lagrangian-Eulerian (ALE) scheme previously developed for simulating bubble growth in polymer foaming [25]. This scheme employs two coordinates: an Eulerian coordinate (x) and a quasi-Lagrangian coordinate (X) fixed on a moving mesh.…”
