Verification of Volume-of-Fluid (VOF) simulation for thin liquid film applications
2009 3rd International Conference on Energy and Environment (ICEE), 2009This paper describes the application of the built-in Volume-of-Fluid (VOF) model in the commercial Computational Fluid Dynamics (CFD) software FLUENTTM and the verification of its accuracy. As the VOF model is based on the field volume fraction calculations and surface reconstruction methods, in which a free surface is not explicitly tracked, the aim ...

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.

Effect of dynamic contact angle in a volume of fluid (VOF) model for a microfluidic capillary flow
Journal of Colloid and Interface Science, 2009We perform three-dimensional numerical and experimental study of the dynamic contact angle using volume of fluid (VOF) method applied to microfluidic channels with integrated pillars. Initially, we evaluated different dynamic contact angle models (hydrodynamic, molecular kinetic and empirical) for capillary filling of a two-dimensional microchannel ...

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 ...

Optimization of a High Pressure Swirl Injector by Using Volume-of-Fluid (VOF) Method
ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 3, 2010In this paper, the effects of various geometric parameters of a high pressure swirl Gasoline Direct Injector (GDI) on the injection flow quality are investigated. The two-dimensional axisymmetric Navier-Stokes equations coupled with the Volume-of-Fluid (VOF) method were employed for simulation of the formation mechanism of the liquid film inside the ...

The Direct Numerical Simulation of the Rising Gas Bubble With the Volume of Fluid (VOF) Method
Volume 6: Fluids and Thermal Systems; Advances for Process Industries, Parts A and B, 2011A gas-liquid two phase flow is complicated and it has not been understood well thus far, in spite of extensive investigation. Numerical simulation is a potential approach to understand this phenomenon. Although a number of studies have been conducted to understand the behavior of bubbles on the basis of computational fluid dynamics (CFD), it is ...

Volume-of-fluid (VOF) simulations of rise of single/multiple bubbles in sheared liquids
Chemical Engineering Science, 2010Abstract The understanding of the lift force, which governs the lateral migration of bubbles, is important to improve closures for continuum flow models that are used to simulate large-scale dispersed gas–liquid flows. In the present work, the effect of bubble size/shape and more importantly the effect of neighboring bubbles on the magnitude and ...

The calculation of the curvature in Volume of Fluid (VOF) methods is still a challenge, and common approaches involve curve or surface fitting based on volume fractions. In this work, we explore an alternative approach for curvature computation in VOF simulations employing machine learning. The neural network establishes a correlation between curvature

Biphasic flow in porous media is of great interest in several areas, such as petroleum and oil recovery, food impregnation, hydrology, and soil science. In this work, the penetration of an external liquid into a porous medium saturated with air, caused by the macroscopic pressure difference, was studied (impregnation).
