Two-phase flow and oxygen transport in the perforated gas diffusion layer of proton exchange membrane fuel cell [PDF]
, 2019 Liquid water transport in perforated gas diffusion layers (GDLs)is numerically investigated using a three-dimensional (3D)two-phase volume of fluid (VOF)model and a stochastic reconstruction model of GDL microstructures.

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.

Numerical Analysis of a Single Bubble with VOF Method.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991 In order to examine the feasibility of direct simulation of bubbly flows, the applicability of the VOF (volume of fluid) method to the analyses of a single rising bubble was examined in this study. Calculated bubble shapes and terminal velocities under wide ranges of Eotvos number and Morton number were compared with the experimental data summarized by

Free Surface Flow Simulation by a Viscous Numerical Cylindrical Tank
Algorithms, 2019 In order to numerically investigate the free surface flow evolution in a cylindrical tank, a regular structured grid system in the cylindrical coordinates is usually applied to solve control equations based on the incompressible two-phase flow model ...

A space-time discontinuous Galerkin finite element method for two-fluid problems [PDF]
, 2007 A space-time discontinuous Galerkin finite element method for two fluid flow problems is presented. By using a combination of level set and cut-cell methods the interface between two fluids is tracked in space-time. The movement of the interface in space-

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