A volume-of-fluid formulation for the study of co-flowing fluids governed by the Hele-Shaw equations

, 2013
We present a computational framework to address the flow of two immiscible viscous liquids which co-flow into a shallow rectangular container at one side, and flow out into a holding container at the opposite side.

Machine Learning Model for Gas–Liquid Interface Reconstruction in CFD Numerical Simulations

Fluids
The volume of fluid (VoF) method is widely used in multiphase flow simulations to track and locate the interface between two immiscible fluids. The relative volume fraction in each cell is used to recover the interface properties (i.e., normal, location,

The Multicell Volume of Fluid (MC-VOF) Method for the Free Surface Simulation of MFD Flows. Part I: Mathematical Model

ISIJ International, 2011
This paper is the first part of a two-part paper which presents a simulation algorithm of unsteady, electromagnetically driven molten metal flows with free surfaces. At the free boundary, the variable space-distribution of the normal Lorentz forces is taken into account by proper computation of the electromagnetic field and pressure.

Studies on hydrodynamic deformation and fragmentation of melt jet injected into water pool using level set method

Results in Physics, 2019
The molten core material (corium) that can be formed during severe accident scenarios in light water reactors (LWRs) can drop in the water pool and form a “melt jet” (hereafter referred to as “jet”) flow.
