Local simulation of sloshing jet in a rolling tank by viscous-inviscid interaction method

open access: yesResults in Engineering, 2021
In this paper, the local behavior of the jet induced by the fluid impact is studied by a new viscous-inviscid interaction (VII) method. This method is based on the inviscid Eulerian-Langrangian (IEL) scheme implemented by the boundary element method (BEM)

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter-sized alginate hydrogel beads. [PDF]

open access: yesAIChE J
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation. Next, we measured the perimeter and circularity of hydrogel beads as

A Volume of Fluid (VOF) Method for the Simulation of Metallurgical Flows

open access: yesISIJ International, 2001
A finite difference numerical method, based on the VOF approach for tracking interface distortions, is presented. It is capable of accurately simulating the fluid flow of multiple immiscible fluids for metallurgical applications. This volume tracking method is based on piecewise linear reconstructions of interfaces, density distributions based on a ...

Numerical simulation of single droplet dynamics in three-phase flows using ISPH [PDF]

open access: yes, 2013
In this study, a new surface tension formulation for modeling incompressible, immiscible three-phase fluid flows in the context of incompressible smoothed particle hydrodynamics (ISPH) in two dimensions has been proposed.

Full-Eulerian Finite-Difference Simulation of Fluid Flow in Hyperelastic Wavy Channel

open access: yesJournal of Fluid Science and Technology, 2010
Fluid flows interacting with deformable wavy channel are simulated by a newly developed full-Eulerian simulation method. A single set of the governing equations for fluid and solid is employed, and a volume-of-fluid (VOF) function is used for describing ...

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 ...

A volume-of-fluid method for interface-resolved simulations of phase-changing two-fluid flows [PDF]

open access: yes, 2020
We present a numerical method for interface-resolved simulations of evaporating two-fluid flows based on the volume-of-fluid (VoF) method. The method has been implemented in an efficient FFT-based two-fluid Navier-Stokes solver, using an algebraic VoF ...

The volume of fluid method in spherical coordinates [PDF]

open access: yes, 2000
The volume of fluid (VOF) method is a numerical technique to track the developing free surfaces of liquids in motion. This method can, for example, be applied to compute the liquid flow patterns in a rotating cone reactor.
