3D Volume-of-Fluid (VOF) Based Simulation of Water Impact Problem Using Navier-Stokes Computations

Volume 1A: Symposia, Part 2, 2015
In this paper, a three-dimensional (3D) numerical investigation of dam-break and water entry problems with emphasis on the water impact loading is presented. Flow fields of incompressible viscous fluids are solved using unsteady Navier-Stokes equations (NS).

Non-dissipative cloud transport in Eulerian grid models by the volume-of-fluid (VOF) method

Atmospheric Environment, 2005
Abstract The formation of clouds is coupled to the vapour saturation condition. Cloud modelling is therefore dramatically disturbed by dilution processes, which are induced by recurrent interpolations on the fixed (Eulerian) grid. The numerical diffusion gives rise to degeneration and premature disappearance of the modelled clouds.

The Direct Numerical Simulation of the Rising Gas Bubble With the Volume of Fluid (VOF) Method

Volume 6: Fluids and Thermal Systems; Advances for Process Industries, Parts A and B, 2011
A gas-liquid two phase flow is complicated and it has not been understood well thus far, in spite of extensive investigation. Numerical simulation is a potential approach to understand this phenomenon. Although a number of studies have been conducted to understand the behavior of bubbles on the basis of computational fluid dynamics (CFD), it is ...

A second order volume of fluid (VOF) scheme for numerical simulation of 2-D breaking waves

Journal of Marine Science and Application, 2007
Among all environmental forces acting on ocean structures and marine vessels, those resulting from wave impacts are likely to yield the highest loads. Being highly nonlinear, transient and complex, a theoretical analysis of their impact would be impossible without numerical simulations.

Improved volume-of-fluid (VOF) model for predictions of velocity fields and droplet lengths in microchannels

Flow Measurement and Instrumentation, 2016
Abstract Accurate measurement of flow in microchannels is imperative to better understand their flow behaviour, which aids in the design of microfluidic devices. In this work, we present an improved VOF model based on smoothing functions that can effectively minimise the issue of spurious velocities, which causes numerical simulations in ...

Analysis of Nanofluid Flow Over a Heated Circular Cylinder using the Volume of Fluid (VOF) Approach

Journal of Advanced Research in Fluid Mechanics and Thermal Sciences
This study employs a two‐phase Volume of Fluid (VOF) model to investigate the flow and heat transfer characteristics of Al₂O₃-water nanofluid over a heated circular cylinder at a Reynolds number of 100. Nanoparticle volume fractions (Φ) ranging from 1% to 10% were analyzed.
