Numerical Simulation of Bubble Coalescence using a Volume of Fluid (VOF) Model
, 1998 This paper presents a Volume Tracking model developed with the specific objective of studying the time – dependent behavior of multiple, “large” gas bubbles rising in an initially quiescent liquid. The model, based on the Volume – Of – Fluid concept, employs an advanced interface tracking scheme known as Youngs’ VOF to advance the gas – liquid ...

COMPARISON BETWEEN EULERIAN AND VOF MODELS FOR TWO-PHASE FLOW ASSESSMENT IN VERTICAL PIPES
CT&F Ciencia, Tecnología & FuturoThe appropriate characterization of the two-phase flow has been recently considered as a topic of interest at industrial level. The Computational Fluid Dynamics (CFD) is one of the techniques used for this analysis.

3D avalanche flow modeling using OpenFOAM
Труды Института системного программирования РАН, 2018 In this paper, a model of a snow avalanche was created with the help of open source CFD software OpenFOAM. The avalanche is considered as a turbulent two-phase flow - snow and air. We take incompressible Herschel-Balkley fluid as a model of snow.

, 2007 A sub-grid mix model based on a volume-of-fluids (VOF) representation is described for computational simulations of the transient mixing between reactive fluids, in which the atomically mixed components enter into the reactivity. The multi-fluid model allows each fluid species to have independent values for density, energy, pressure and temperature, as

Abstract Simulating complex hydraulic conditions, particularly two-phase flows over spillway chutes, can be achieved with high accuracy using three-dimensional numerical models. This study investigates the potential for vacuum generation and cavitation phenomena on the Aghchai Dam service spillway through numerical simulations conducted
