first examine the viscous effect on the early-time drop deformation, comparing with theory …

Manifold death: a volume of fluid implementation of controlled topological changes in thin sheets by the signature method

L Chirco, J Maarek, S Popinet, S Zaleski - Journal of Computational …, 2022 - Elsevier
A well-known drawback of the Volume-Of-Fluid (VOF) method is that the breakup of thin
liquid films or filaments is mainly caused by numerical aspects rather than by physical ones …

Subgrid scale modeling of droplet bag breakup in VOF simulations

A Han, O Desjardins - International Journal of Multiphase Flow, 2024 - Elsevier
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 computational …

Impact of inlet gas turbulence on the formation, development and breakup of interfacial waves in a two-phase mixing layer

D Jiang, Y Ling - Journal of Fluid Mechanics, 2021 - cambridge.org
Understanding the development and breakup of interfacial waves in a two-phase mixing
layer between the gas and liquid streams is paramount to atomization. Due to the velocity …

A consistent mass–momentum flux computation method for the simulation of plunging jet

C Liu, R Gao, C Hu - Physics of Fluids, 2022 - pubs.aip.org
In the present study, a robust and conservative numerical scheme is proposed to simulate
