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

open access: yesFluids
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,

Numerical Analysis of a Single Bubble with VOF Method.

open access: yesTRANSACTIONS 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

General energy bounds for systems of bosons with soft cores

open access: yes, 2000
We study a bound system of N identical bosons interacting by model pair potentials of the form V(r) = A sgn(p)r^p + B/r^2, A > 0, B >= 0. By using a variational trial function and the `equivalent 2-body method', we find explicit upper and lower bound ...

Free Surface Flow Simulation by a Viscous Numerical Cylindrical Tank

open access: yesAlgorithms, 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 ...

Integrated Numerical Modelling System for Extreme Wave Events at the Wave Hub Site [PDF]

open access: yes, 2013
This paper examines an extreme wave event which occurred during a storm at the Wave Hub site in 2012. The extreme wave of 9.57 m height was identified from a time series of the heave data collected by an Oceanor Seawatch Mini II Buoy deployed at the site.

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

open access: yesPolish 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.

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

open access: yes, 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.
