Computational Modeling of Bubbles Growth Using the Coupled Level Set-Volume of Fluid Method. [PDF]

Eur J Mech B Fluids, 2020
Understanding the generation, growth, and dynamics of bubbles as they absorb or release dissolved gas in reactive flows is crucial for optimizing the efficiency of electrochemically gas-evolving systems like alkaline water electrolysis or hydrogen ...

A momentum-conserving, consistent, Volume-of-Fluid method for incompressible flow on staggered grids [PDF]

, 2018
The computation of flows with large density contrasts is notoriously difficult. To alleviate the difficulty we consider a consistent mass and momentum-conserving discretization of the Navier-Stokes equation.

Coupling non-local rheology and volume of fluid (VOF) method: a finite volume method (FVM) implementation [PDF]

EPJ Web of Conferences, 2021
Additional to a behavior switching between solid-like and liquid-like, dense granular flows also present propagating grain size-dependent effects also called non-local effects. Such behaviors cannot be efficiently modeled by standard rheologies such as µ(

Improvement of a Simple Coupled VOF with LS (S-CLSVOF) Method

Journal of Chemical Engineering of Japan, 2023
In this study, an efficient conversion algorithm of level set function [Formula: see text] from volume fraction [Formula: see text] is developed. This method makes the calculation of [Formula: see text] easier than the conventional CLSVOF method, and the

Unified modeling of cavitating sprays using a three-component volume of fluid method accounting for phase change and phase miscibility

The Physics of Fluids, 2022
In this study, a new three-fluid volume of fluid framework is presented in order to be used as a tool for providing physical insight—in a unified manner—to cavitating sprays and other complex multi-fluid, multiphase fluid flows.

A multiscale volume of fluid method with self-consistent boundary conditions derived from molecular dynamics

The Physics of Fluids, 2021
Molecular dynamics (MD) and volume of fluid (VOF) are powerful methods for the simulation of dynamic wetting at the nanoscale and macroscale, respectively, but the massive computational cost of MD and the sensitivity and uncertainty of boundary ...

Tumescent Injections in Subcutaneous Pig Tissue Disperse Fluids Volumetrically and Maintain Elevated Local Concentrations of Additives for Several Hours, Suggesting a Treatment for Drug Resistant Wounds. [PDF]

, 2020
PurposeBolus injection of fluid into subcutaneous tissue results in accumulation of fluid at the injection site. The fluid does not form a pool. Rather, the injection pressure forces the interstitial matrix to expand to accommodate the excess fluid in ...
