Subgrid scale modeling of droplet bag breakup in VOF simulations
Austin Han, Olivier Desjardins
The mesh-dependency of the breakup of liquid films, including their breakup length scales and resulting drop size distributions, has long been an obstacle inhibiting the computatio…

Capturing thin structures in VOF simulations with two-plane reconstruction
Austin Han, Robert Chiodi, Olivier Desjardins
A novel interface reconstruction strategy for volume of fluid (VOF) methods is introduced that represents the liquid-gas interface as two planes that co-exist within a single compu…

Comparison of methods for curvature estimation from volume fractions
Austin Han, Fabien Evrard, Olivier Desjardins
This paper evaluates and compares the accuracy and robustness of curvature estimation methods for three-dimensional interfaces represented implicitly by discrete volume fractions o…
