Abstract The melting behavior of a fayalitic slag was investigated with computational fluid dynamics and validated experimental data. A heating microscope employed to perform typical ash (AMB) test, in order gain information about the slag. numerical approach is based on using volume (VOF) method, track interface between gas phases, enthalpy–porosity model, simulate as phase change material (PC...

gas-lift pumps are devices for lifting liquid phase incorporating the gas phase to be injected in the bottom of liquid column. they are widely used in various industrial applications such as oil extracting in petroleum industries. gas-liquid flow being the main part of the flow through these systems, flowing in vertical pipes of gas-lift pumps has different regimes namely bubbly, slug, churn an...

The paper describes a novel implementation of the piecewise linear interface-capturing volume-of-fluid method (PLIC-VOF) in axisymmetric cylindrical coordinates. principal innovative feature involved this work is that both forward and inverse reconstruction problems are solved analytically, resulting an appreciable speed-up computing time comparison with iterative approach. All formulae introdu...

This paper proposes a comparison of four popular interface capturing methods : the volume fluid (VOF), standard level set (SLS), accurate conservative (ACLS) and coupled (CLSVOF). All are embedded into unified low-Mach framework based on Cartesian-grid finite-volume discretization. includes sharp transport interface, well-balanced surface tension discretization consistent mass momentum which al...

Two-phase flows with dynamic interfaces are ubiquitous in daily life as well as in many industrial applications. Gas bubbles and liquid droplets are typical forms of these twophase flows. In chemical engineering, understanding the dynamics of these bubbles and droplets is crucial to the design and operation of the two-phase flow reactors, ranging from microfluidic devices to large systems such ...

Marine submersible buoy systems are widely-used equipment for ocean resource development. The marine system studied in this paper consists of the buoy, battery compartment, anchor block, mooring line, and power supply cable. To study mechanical behavior obtain speed variation each component during last deployment, establishes free surface computational fluid dynamics model based on VOF method. ...
