A fictitious domain/finite element method for particulate flows
TL;DR: A finite element method for the direct numerical simulation of 3D incompressible fluid flows with suspended rigid particles which avoids the need to grid the rigid particles and solves the entire problem on a single Eulerian grid.

Two-way coupling of Eulerian–Lagrangian model for dispersed multiphase flows using filtering functions
TL;DR: In this article, a new calculation method for dispersion-to-continuous phase interaction, which is accompanied by spherical dispersion migration, is proposed, and the basic principle of the method is the introduction of Lagrangian filtering functions which convert discrete dispersion volume fractions to a spatially differentiable distribution.

Numerical computation of thermally controlled steam bubble condensation using Moving Particle Semi-implicit (MPS) method
TL;DR: In this paper, single steam bubble condensation behaviors in subcooled water have been simulated using Moving Particle Semi-implicit (MPS) method, where the liquid phase was modeled using moving particles and the two phase interface was set to be a movable boundary which can be tracked by the topological position of the interfacial particles.

A 3D Unsplit Forward/Backward Volume-of-Fluid Approach and Coupling to the Level Set Method
Vincent Le Chenadec,Heinz Pitsch +1 more
TL;DR: This paper presents a novel methodology for interface capturing in two-phase flows by combining a Lagrangian-Eulerian Volume-of-Fluid approach with a Level Set method, which is shown to be less restrictive in terms of CFL conditions than split Volume- of-fluid methods.

A level set technique applied to unsteady free surface flows
TL;DR: In this article, an unsteady Navier-Stokes solver for incompressible fluid is coupled with a level set approach to describe free surface motions, where the two-phase flow of air and water is approximated by the flow of a single fluid whose properties, such as density and viscosity, change across the interface.

Volume of fluid (VOF) method for the dynamics of free boundaries
C.W Hirt,B. D. Nichols +1 more
TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.
