Numerical simulation Of bubble behavior using VOF method

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
Taking 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, 2010
Abstract 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, 2010
In 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, 2009
The 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, 2004
AbstractThis 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, 2004
AbstractThis 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

Numerical Simulation of Bubble Coalescence Based on VOF Method

Applied Mechanics and Materials, 2011
This paper takes bubbles of bubble shell as research object, mainly studies two bubbles arranged in a vertical position. Applying VOF (volume of fluid) method to simulate interaction between two bubbles, analyses the effect of center distances and diameters on deformation and coalescence of bubbles.

On Two-Dimensional Water-Solid Impact With VOF Methods

Fluids Engineering, 1995
Abstract Procedures are presented that allow an accurate treatment with the Volume of Fluid (VOF) method of the impact between an incompressible fluid and solid boundaries. The identification and correct handling of impact are made possible by the use of appropriate procedures for the treatment of fluid and obstacle cells along the solid
