Mass transfer and chemical reactions in bubble swarms with dynamic interfaces

“…In these methods, the flow is solved for on a single grid with the two phases being identified by marker particles and marker functions. These methods are widely used 41,42 despite the difficulties associated with accurately defining the interface and computing surface tension and mass transfer. Recently, Bothe et al 43 performed VOF-based numerical simulations of the mass transfer of a gas from deformable bubbles and bubble chains.…”

Methane bubble formation and dynamics in a rectangular bubble column: A CFD study

“…The motion of bubbles and changes in the liquid are tracked using a single set of momentum equations. Each fluid is tracked independently and the fraction of fluid volume in the grid is indicated by the indicator function F. The indicator F can be qualified by 0 for a cell containing only gas, by 1 for a liquid-filled cell and by 0-1 for a cell containing both gas and liquid [11,16,23,[43][44][45].…”

Time scale analysis for fluidized bed melt granulation-II: Binder spreading rate

“…The OEB method models liquid spreading process on solid surfaces by considering the potential energy due to interfacial tension and kinetic energy balanced by the energy dissipation during spreading. The VOF, on the other hand, includes four common methods: (1) Fluxcorrected transport by Boris and Book (1973), (2) Lagrangian piecewise linear interface construction by van Wachem and Schouten (2004), (3) Compressive interface capturing scheme for arbitrary meshes (CICSAM) by Ubbink(1997) and (4) inter-gamma scheme by Jasak and Weller (1995). Each of these methods employs a different approach to track the phase interface.…”
