Quantitative comparison of dam break and bubble flows based on CF-VOF and IR-VOF schemes

International Journal of Modern Physics C, 2023
In this study, an incompressible and immiscible two-phase flow solver was employed to assess the accuracy of phase-interface capturing methods in simulating two-phase flows. Three benchmark investigations were conducted involving two dam break flows with deformable free surfaces and the upward motion of a gas bubble through a liquid column. Four phase-

VOF Method for Impinging-Jet Atomizers

Energy & Fuels, 2010
Impinging jet atomization is an effective method to produce fine sprays for extremely high viscosity fuels such as coal water slurry (CWS). This technique has been used successfully in a number of CWS applications since its inception. The purpose of this study is to analyze the effect of liquid viscosity and jet velocity in an impinging jet atomizer ...

Adaptive VOF with curvature‐based refinement

International Journal for Numerical Methods in Fluids, 2007
AbstractAdaptive refinement is implemented in the context of the volume‐of‐fluid (VOF) methodology in order to study the efficacy of resolving interfaces adaptively based on the local value of curvature. The usual uniform mesh VOF implementation is modified slightly to ensure accurate advection of fluxes between cells at different resolutions.

An Advanced VOF Algorithm for Oil Boom Design

International Journal of Modelling and Simulation, 2006
In this paper, an accurate interface convection technique based on the volume-of-fluid (VOF) scheme is presented and the concepts of interface basis and three types of fluxes are introduced to handle two-layer fluid flow in complex geometric situations. The scheme was tested and the results proved to be accurate.

An Adaptive VOF Method on Unstructured Grid

AIP Conference Proceedings, 2011
In order to improve the accuracy of interface capturing and keeping the computational efficiency, an adaptive VOF method on unstructured grid is proposed in this paper. The volume fraction in each cell is regarded as the criterion to locally refine the interface cell.
