Effects of surfactant on propagation and rupture of a liquid plug in a tube.
TL;DR: Surfactant-laden liquid plug propagation and rupture occurring in lower lung airways are studied computationally using a front-tracking method and even a tiny amount of surfactant significantly reduces the pressure and shear stress and thus improves cell survivability.

Numerical study of breaking waves by a two‐phase flow model
TL;DR: In this paper, a two-phase flow model is presented for modeling breaking waves in deep and shallow water, including wave pre-breaking, overturning and post-breaking processes, based on the Reynolds-averaged Navier-Stokes equations with the k −e turbulence model.

A monolithic mass tracking formulation for bubbles in incompressible flow
TL;DR: This work proposes a new fully monolithic approach to coupling incompressible flow to fully nonlinear compressible flow including the effects of shocks and rarefactions, and makes a number of simplifying assumptions on the air flow removing not only the nonlinearities but also the spatial variations of both the density and the pressure.

Numerical Methods for Dispersed Multiphase Flows
TL;DR: The major part of this article is focused on the modelling of dispersed multi-phase flows relying on the point-particle assumption and it is demonstrated that the Euler/Lagrange approach may also be used to study an industrial filtration process where it allows the prediction of particle deposits and filter cake formation.

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.
