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.

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.

Experimental Validation of VOF Method in Microchannel Flows
2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE), 2021This study is concerned with the two-phase flow in a microchannel. The liquids are Newtonian (de-ionized water and sunflower oil) and a Y-shaped microchannel is used. For this microfluidic device, numerical and experimental studies were conducted. The focus of this study is on the evolution of the interface and what happens at it, in terms of stresses,

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/

VOF Method for Fluids and Solids on Octree Structure
2009 Second International Conference in Visualisation, 2009Fluid simulation, proposed here, runs on an unrestricted octree data structure which uses mesh refinement techniques to enable higher level of detail and solves Navier Stokes equations for multiple fluids. We also show our solution for floating objects and unmoving obstacles by setting up the boundry conditions and solving the velocity of objects using

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
