A suitable parametrization to simulate slug flows with the Volume-Of-Fluid method [PDF]

open access: yes, 2012
Diffuse–interface methods, such as the Volume-Of-Fluid method, are often used to simulate complex multiphase flows even if they require significant computation time.

Hydrodynamics of single bubble rising through water column using volume of fluid (VOF) method

open access: yesJournal of Thermal Engineering, 2021
The importance of air bubble dynamics in liquid is in some phenomena like chemical and biochemical processes in refinery units. The 2D Volume of Fluid (VOF) method together with the CFD technique were employed for simulating. The dynamic meshing technique is used to simulate the hydrodynamics of rising air bubble in liquid water column via the User ...

Large-Eddy Simulation of a Hydrocyclone with an Air Core Using Two-Fluid and Volume-of-Fluid Models

open access: yesFluids, 2021
Large-eddy simulations have been conducted for two-phase flow (water and air) in a hydrocyclone using Two-Fluid (Euler–Euler) and Volume-of-Fluid (VOF) models. Subgrid stresses are modeled using a dynamic eddy–viscosity model, and results are compared to

Direct Numerical Simulation of Complex Gas-Liquid-Solid Flows using a Combined\ud Immersed Boundary (IB) and Volume Of Fluid (VOF) Approach [PDF]

open access: yes, 2006
In this paper a simulation model is presented for the Direct Numerical Simulation (DNS) of complex multi-fluid flows in which simultaneously (moving) deformable (drops or bubbles) and non-deformable (moving) elements (particles) are present, possibly ...

Computational fluid dynamics applied to gas-liquid contactors. [PDF]

open access: yes, 1997
In this paper a `hierarchy of models¿ is discussed to study the fluid dynamic behaviour of gas-liquid bubble columns. This `hierarchy of models¿ consists of a Eulerian-Eulerian two fluid model, a Eulerian-Lagrangian discrete bubble model and a Volume ...

A Machine Learning Approach to Volume Tracking in Multiphase Flow Simulations

open access: yesFluids
This work presents a machine learning (ML) approach to volume-tracking for computational simulations of multiphase flow. It is an alternative to a commonly used procedure in the volume-of-fluid (VOF) method for volume tracking, in which the phase ...
