Accurate and efficient surface reconstruction from volume fraction data on general meshes [PDF]

open access: yes, 2019
Simulations involving free surfaces and fluid interfaces are important in many areas of engineering. There is, however, still a need for improved simulation methods. Recently, a new efficient geometric VOF method called isoAdvector for general polyhedral

Application of CLEAR-VOF method to wave and flow simulations

open access: yesWater Science and Engineering, 2012
A two-dimensional numerical model based on the Navier-Stokes equations and computational Lagrangian-Eulerian advection remap-volume of fluid (CLEAR-VOF) method was developed to simulate wave and flow problems. The Navier-Stokes equations were discretized

Hybrid VOF–Lagrangian CFD Modeling of Droplet Aerobreakup

open access: yesApplied Sciences, 2022
A hybrid VOF–Lagrangian method for simulating the aerodynamic breakup of liquid droplets induced by a traveling shock wave is proposed and tested. The droplet deformation and fragmentation, together with the subsequent mist development, are predicted by ...

Numerical analysis of the hydrodynamic behaviour of immiscible metallic alloys in twin-screw rheomixing process [PDF]

open access: yes, 2006
A numerical analysis by a VOF method is presented for studying the hydrodynamic mechanisms of the rheomixing process by a twin-screw extruder (TSE). The simplified flow field is established based on a systematic analysis of flow features of immiscible ...

Large droplet impact on water layers [PDF]

open access: yes, 2004
The impact of large droplets onto an otherwise undisturbed layer of water is considered. The work, which is motivated primarily with regard to aircraft icing, is to try and help understand the role of splashing on the formation of ice on a wing, in ...

The CFD Method-Based Research on Damaged Ship’s Flooding Process in Time-Domain

open access: yesPolish Maritime Research, 2019
The flooding process is one of the main concerns of damaged ship stability. This paper combines the volume of fluid (VOF) method incorporated in the Navier-Stokes (NS) solver with dynamic mesh techniques to simulate the flooding of a damaged ship.
