Numerical simulation of multiphase flows using an enhanced Volume-of-Fluid (VOF) method
International Journal of Mechanical Sciences, 2022The main objective of the present work is to enhance the stability and accuracy of Volume-of-Fluid (VOF) method for simulating multiphase flow problems with large density ratios and moving interfaces. In order to accomplish this, a novel high-order TVD flux-limiter scheme is developed and applied to approximate the convective fluxes in the momentum ...

Volume of fluid (VOF) method for the dynamics of free boundaries
Journal of Computational Physics, 1981Several methods have been previously used to approximate free boundaries in finite-difference numerical simulations. A simple, but powerful, method is described that is based on the concept of a fractional volume of fluid (VOF). This method is shown to be more flexible and efficient than other methods for treating complicated free boundary ...

The clearance of mucus through coughing is a complex, multiphase process, which is affected principally by mucus viscosity and airflow velocity; however, it is also critically affected by the thickness of the two layers of mucus-the serous and gel layers-and oscillation level. The present study examines the effects of the latter parameters more closely.

Summary: The volume-of-fluid (VOF) method is adopted for the finite element analysis of transient fluid flow with a free surface. In particular, an adaptation technique for generating an adaptive grid is incorporated to capture a higher resolution of the free surface configuration.

SIMULATION, 2021
In this paper, the effects of water on obstacles in dam-break flow for different angles of the inclined planes have been numerically examined. The presented computational data are compared with data from the experiment and computational simulation data of other authors.

Modelling of Hydraulic Seals Using an Axisymmetric Volume of Fluid Method (VOF)
Volume 2: Aircraft Engine; Coal, Biomass and Alternative Fuels; Cycle Innovations, 2013Hydraulic seals are used in aero engines because of their excellent sealing properties. Sealing of oil inside bearing chambers is extremely important as leakage of oil into internal spaces of the engine increases the oil consumption and can result in undesirable effects, ranging from cosmetic to mechanical.

Two phase analysis of sloshing in a rectangular container with Volume of Fluid (VOF) methods
Ocean Engineering, 2013Abstract Free surface oscillations of a liquid confined in a closed container (sloshing phenomenon) are an important issue when big amounts of liquid are industrially transported. The phenomenon involves two fluids that share a free surface boundary separating them, normally the density of the upper fluid is several orders of magnitude less than the ...
