An interface-capturing method for incompressible two-phase flows. Validation and application to bubble dynamics (2007, methodology): “…issue encountered in both Lagrangian and Eulerian techniques, such as Boundary Elements (Zhou and Pozrikidis, 1993) and Front Tracking methods (Bunner and Tryggvason, 2002) whose transport algorithms are not explicitly conservative, but also in Level Set methods that use a redistanciation…”
Numerical simulation of bubble rising in viscous liquid (2007, background): “Similar to that of Tryggvason et al. [27], we also use a fixed, regular, staggered grid, but discretize the momentum equations using finite volume method.”
Effect of bubble deformation on the properties of bubbly flows (2003, methodology): “Jan (1994), Bunner & Tryggvason (2002a) and Oka & Ishii (1999) showed that this leads to negligible differences in the results.”
Hydrodynamic interactions between two spherical bubbles rising side by side in a viscous liquid (2003, background): “As demonstrated by Bunner & Tryggvason (2002), it is now possible to compute the evolution of some hundreds of bubbles on a fixed numerical grid.”
Direct numerical simulations of gas/liquid multiphase flows (2011, methodology): “The simulations of Bunner and Tryggvason (2002b) also showed that while the Reynolds stress tensor scaled in a way predicted by potential flow cell models, and while the horizontal velocity fluctuations were comparable in magnitude, the vertical velocity fluctuations were considerably higher.”
Three-dimensional vortex structures under breaking waves (2005, background): “There can also be intensiﬁcation of small-scale turbulence around bubbles, via wake eﬀects in bubble-bubble interactions (Bunner & Tryggvason 2002 a ).”
Single bubble rising dynamics for moderate Reynolds number using Lattice Boltzmann Method (2010, background): “And, third, force is defined as it was suggested by Bunner and Tryggvason [40], G 1⁄4 ðq qaveÞgrh, where qave is the average density, which is introduced to guarantee that the net momentum flux across the boundaries in the domain is zero.”
On the drag force of bubbles in bubble swarms at intermediate and high Reynolds numbers (2011, unknown): “Bunner and Tryggvason (2002) already mentioned that”
