Level set methods for fluid interfaces
James A. Sethian,Peter Smereka +1 more
TL;DR: An overview of level set methods, introduced by Osher and Sethian, for computing the solution to fluid-interface problems, which are computational techniques that rely on an implicit formulation of the interface, represented through a time-dependent initial-value partial-differential equation.

Quasi–incompressible Cahn–Hilliard fluids and topological transitions
John Lowengrub,Lev Truskinovsky +1 more
TL;DR: In this article, a physically motivated regularization of the Euler equations is proposed to allow topological transitions to occur smoothly, where the sharp interface is replaced by a narrow transition layer across which the fluids may mix.

A Level Set Formulation of Eulerian Interface Capturing Methods for Incompressible Fluid Flows
TL;DR: Eulerian finite difference methods based on a level set formulation derived for incompressible, immiscible Navier?Stokes equations are proposed and are capable of computing interface singularities such as merging and reconnection.

A diffuse-interface method for simulating two-phase flows of complex fluids
TL;DR: In this paper, the authors proposed a diffuse-interface approach to simulating the flow of two-phase systems of microstructured complex fluids, where the energy law of the system guarantees the existence of a solution.

An improved level set method for incompressible two-phase flows
TL;DR: A level set method for capturing the interface between two fluids is combined with a variable density projection method to allow for computation of a two-phase flow where the interface can merge/break and the flow can have a high Reynolds number.

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.
