Hydrodynamic analysis of human swimming based on VOF method
Computer Methods in Biomechanics and Biomedical Engineering, 2017A 3-D numerical model, based on the Navier-Strokes equations and the RNG k-ε turbulence closure, for studying hydrodynamic drag on a swimmer with wave-making resistance taken into account is established. The volume of fluid method is employed to capture the undulation of the free surface.

A VOF Method for Isobaric Expandable Flows
PAMM, 2012AbstractIn this paper a method is described to simulate isobaric multiphase flows at low Mach numbers with steep temperature gradients for fluids with non‐negligible thermal expansivity. Governing equations and solution procedure are outlined. Further, a test case is shown in order to verify the model.

Numerical simulation Of bubble behavior using VOF method
2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011Taking full account of the liquid viscosity, surface tension and other factors, a detailed numerical simulation using VOF method was carried out to study the dynamic behavior of bubbles in still water, and obtained the rising path, deformation process and speed changes. The numerical results were compared with experimental data, and gained good result.

Simulation of shallow water waves using VOF method
Journal of Hydro-environment Research, 2010Abstract In this study, the transformation of groupy waves and plunging breakers as they travel to a breaking point in a coastal zone is two dimensionally investigated. The governing equations are momentum, continuity and Fractional Volume Of Fluid (VOF) function equations. The fluid is assumed to be viscous and incompressible.

A SLIC–VOF Method Based on Unstructured Grid
Microgravity Science and Technology, 2010In this paper, an interface reconstruction technology similar with SLIC method on structured grid is developed for the unstructured grid. For a cell containing the interface, a straight line segment parallel with one edge of the triangle cell is set to the interface according to the VOF function values in the three neighbor cells and volume flux of the

Simulation of Dendritic Growth Using a VOF Method
Volume 1: Symposia, Parts A, B and C, 2009The volume of fluid (VOF) method is one of the most widely used methods to simulate interfacial flows using fixed grids. However, its application to phase change processes in solidification problems is relatively infrequent. In this work, preliminary results of the application of a new methodology to the simulation of dendritic growth of pure metals is

Finite‐volume‐type VOF method on dynamically adaptive quadtree grids
International Journal for Numerical Methods in Fluids, 2004AbstractThis paper describes a finite‐volume volume‐of‐fluid (VOF) method for simulating viscous free surface flows on dynamically adaptive quadtree grids. The scheme is computationally efficient in that it provides relatively fine grid resolution at the gas–liquid interface and coarse grid density in regions where flow variable gradients are small ...

3D two phase flows numerical simulations by SL‐VOF method
International Journal for Numerical Methods in Fluids, 2004AbstractThis paper describes the development of a semi‐Lagrangian computational method for simulating complex 3D two phase flows. The Navier–Stokes equations are solved separately in both fluids using a robust pseudo‐compressibility method able to deal with high density ratio. The interface tracking is achieved by the segment Lagrangian volume of fluid
