Numerical Modeling of Water Jet Plunging in Molten Heavy Metal Pool
Mathematics, 2023 The hydrodynamic and thermal interaction of water with the high-temperature melt of a heavy metal was studied via the Volume-of-Fluid (VOF) method formulated for three immiscible phases (liquid melt, water, and water vapor), with account for phase ...

On algebraic TVD-VOF methods for tracking material interfaces [PDF]
Computers & Fluids, 2019 We revisit simple algebraic VOF methods for advection of material interfaces based of the well established TVD paradigm. We show that greatly improved representation of contact discontinuities is obtained through use of a novel CFL-dependent limiter whereby the classical TVD bounds are exceeded.

Lattice Boltzmann simulation of droplet behaviour in microfluidic devices [PDF]
, 2008 We developed a lattice Boltzmann model to investigate the droplet dynamics in microfluidic devices. In our model, a stress-free boundary condition was proposed to conserve the total mass of flow system and improve the numerical stability for flows with ...
