Volume of fluid (VOF) methods are extensively used to track interfaces in numerical simulations, and many VOF algorithms require that the interface be reconstructed geometrically. For this purpose, Piecewise Linear Interface Construction (PLIC) technique is most frequently used, which for reasons geometric complexity can slow difficult implement. Here, we propose an alternative neural network b...

Heat & fluid flow conservation equations of carburant liquid droplet are solved by a semi-implicit method the Volume Of Fluid ( VOF ) scheme. A new technique radius regression estimation based on Piece-wise Linear Interface Calculation PLIC is developed. Numerical computation performed for stagnant droplets in evaporation natural convection (which takes into consideration buoyancy forces) and a...

We present a novel interface-capturing scheme, THINC-scaling, to unify the VOF (volume of fluid) and level set methods, which have been developed as two different approaches widely used in various applications. The key success is maintain high-quality THINC reconstruction function using field accurately retrieve geometrical information fulfill numerical conservativeness. interface well defined ...

The transport of fluid, heat ,and particles (bubbles and solid inclusions) in flowing molten steel is investigated in steel refining ladles, the continuous casting tundish, continuous casting mold and strand, and steel ingot casting processes. The two-equation k-ε model is used to simulate the turbulence. Multiphase fluid flow is numerically simulated with a Lagrangian-Eulerian approach, an Eul...

This paper focuses on the implementation, validation and exploitation of a vertical dropshaft flow operation using the commercial VOF-based Computational Fluid Dynamics (CFD) code, FLOW-3D ® . Using the experimental data of Chanson (2002), the package was used to simulate the flow patterns in a rectangular dropshaft with plunge-flow pattern. Both k−ε and k−ε RNG turbulence closures were tested ...
