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 ...

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.

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 ...

Transient simulations of cavitating flows using a modified volume-of-fluid (VOF) technique
International Journal of Computational Fluid Dynamics, 2008In this study, transient 2D/axisymmetric simulations of cavitating flows are performed using a modified 'Volume-of-Fluid' (VOF) technique. Simulation of the cavitation is based on a homogenous equilibrium flow model. To predict the shape of the cavity, the Navier-Stokes equations in addition to an advection equation for the liquid volume fraction are ...

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.

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 ...
