Numerical Modelling of Unsteady Partial Cavities Behind a Backward Facing Step [PDF]

, 2001
This paper presents some calculation results in the cases of steady and non-steady partial cavity. These results are obtained with the commercial Navier-Stokes codes FLUENT and STAR-CD and compared with experimental results.

Assessment of volume of fluid and immersed boundary methods for droplet computations

, 2004
The volume of fluid (VOF) and immersed boundary (IB) methods are two popular computational techniques for multi-fluid dynamics. To help shed light on the performance of both techniques, we present accuracy assessment, which includes interfacial geometry,

A Study of the Volume of Fluid Method for Moving Boundary Problems [PDF]

, 1998
Moving boundary problems are often encountered in engineering and science. One of the methods to solve such problems numerically is the volume of fluid (VOF) method.

Multi-scale modelling of boiling heat transfer: Exploring the applicability of an enhanced volume of fluid method in sub-micron scales

International Journal of Thermofluids
The advancement of technology has led to a significant increase in thermal loads, thus presenting new challenges in heat dissipation. Traditional single-phase cooling systems are often inadequate to meet these demands.

INFLUENCE OF VISCOSITY DIFFERENCE ON THE INSTABILITY OF THE CORE-ANNULAR FLOW

TASK Quarterly, 2003
The process of destabilisation of an axi-symmetric, core-annular flow (CAF) of two Newtonian fully miscible liquids widely differing in viscosity is investigated.

Conservative volume-of-fluid method for free-surface simulations on Cartesian-grids

, 2010
This paper contributes to the state of the art in Cartesian-grid methods through development of new advection and reconstruction Volume-of-Fluid (VOF) algorithms which are applicable to two and three-dimensional flows.

Anti-diffusion method for coupled level set and volume of fluid, volume of fluid, and tangent of hyperbola for interface capturing methods [PDF]

In this paper, we propose an anti-diffusion method to effectively prevent flotsams (non-physical tiny droplets and bubbles) and/or diffusion of the VOF (volume of fluid) function that occur in CLSVOF (coupled level set and volume of fluid), VOF (volume ...
