TLDR
In this article, the authors derived and validated a correlation for the magnitude of these currents as a function of the physical and numerical parameters used in a given simulation, and found that these currents may be limited by both the inertial and viscous terms in the Navier-Stokes equations, and they do not decrease in magnitude with increased mesh refinement or decreased computational time step.About:

An accurate adaptive solver for surface-tension-driven interfacial flows
TL;DR: The method is shown to recover exact equilibrium (to machine accuracy) between surface-tension and pressure gradient in the case of a stationary droplet, irrespective of viscosity and spatial resolution.

Evaluating the performance of the two-phase flow solver interFoam
TL;DR: The performance of the open source multiphase flow solver, interFoam, is evaluated using a variety of verification and validation test cases, which include verification tests for pure advection (kinematics), dynamics in the high Weber number limit and dynamics of surface tension-dominated flows.

Numerical modeling of multiphase flows in microfluidics and micro process engineering: a review of methods and applications
TL;DR: A comprehensive review of numerical methods and models for interface resolving simulations of multiphase flows in microfluidics and micro process engineering is presented in this paper, where three common approaches in the sharp interface limit, namely the volume-of-fluid method with interface reconstruction, the level set method and the front tracking method, as well as methods with finite interface thickness such as color function based methods and the phase-field method are discussed.

A continuum method for modeling surface tension
TL;DR: In this paper, a force density proportional to the surface curvature of constant color is defined at each point in the transition region; this force-density is normalized in such a way that the conventional description of surface tension on an interface is recovered when the ratio of local transition-reion thickness to local curvature radius approaches zero.

Bubbles, Drops, and Particles
TL;DR: In this paper, the authors evaluated the applicability of the standard κ-ϵ equations and other turbulence models with respect to their applicability in swirling, recirculating flows.
Journal ArticleDOI
Direct numerical simulation of free-surface and interfacial flow
TL;DR: In this paper, the authors consider the formation of droplet clouds or sprays that subsequently burn in combustion chambers, which is caused by interfacial instabilities, such as the Kelvin-Helmholtz instability.

Modelling Merging and Fragmentation in Multiphase Flows with SURFER
TL;DR: In this article, the Navier-Stokes equation is solved using staggered finite differences on a MAC grid and a split-explicit time differencing scheme, while incompressibility is enforced using an iterative multigrid Poisson solver.
