Quantitative comparison of dam break and bubble flows based on CF-VOF and IR-VOF schemes
International Journal of Modern Physics C, 2023In 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, 2010Impinging 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, 2007AbstractAdaptive 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, 2006In 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, 2011In 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.

IsoAdvector: Geometric VOF on General Meshes
2019In a recent publication, we presented a novel geometric VOF interface advection algorithm, denoted isoAdvector (Roenby et al. in R Soc Open Sci 3:160405 2016, [1]). The OpenFOAM ® ® implementation of the method was publicly released to allow for more accurate and efficient two-phase flow simulations in OpenFOAM ® ® (Roenby in isoAdvector www.github.com/

Viele halten die gesetzlichen Vorschriften für Ausschreibungen längst für unerträglich kompliziert. Trotzdem muss man sie beachten, sonst können Verträge nichtig sein. Das kostet Nerven, Zeit und Geld. Schlimmstenfalls wird das Verfahren sonst aber zurückgeworfen – auf den Punkt null.

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.
