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 ...

A VOF Method for Isobaric Expandable Flows
PAMM, 2012AbstractIn this paper a method is described to simulate isobaric multiphase flows at low Mach numbers with steep temperature gradients for fluids with non‐negligible thermal expansivity. Governing equations and solution procedure are outlined. Further, a test case is shown in order to verify the model.

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/

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.

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.

Implementation of the VOF Method in the DLR TAU Code
45th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2009The DLR TAU code is enhanced with the volume-of-fluid method (VOF) for a reconstruction of the fluid interface. The compressible Reynolds-Averaged-Navier-Stokes equations are discretized by a finite volume technique using tetrahedra, pyramids, prisms and hexahedra.

A SLIC–VOF Method Based on Unstructured Grid
Microgravity Science and Technology, 2010In 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, 2009The 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
