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…

High-Fidelity Multi-Scale Simulation of Swirled Air-blast Atomization with Comparison against Experiments
Lorenzo Bruni, Olivier Desjardins
In liquid-fueled combustion systems, optimization of the fuel atomization process is critical to reducing fuel consumption and lowering pollutant emissions. Accurate and efficient…
