TL;DR: In this article, a semi-implicit discretization for the convective Cahn-Hilliard equation with high-resolution schemes employed for direct numerical simulations of turbulence is proposed.

TL;DR: An accurate and efficient numerical method to solve the coupled Cahn-Hilliard/Navier-Stokes system, known as Model H, that constitutes a phase field model for density-matched binary fluids with variable mobility and viscosity, and solves the Navier- Stokes equations with a robust time-discretization of the projection method that guarantees better stability properties than those for Crank-Nicolson-based projection methods.

TL;DR: A sharp interface capturing method is described for the study of incompressible multiphase flows with phase change using the level set method to keep track of the interface between the two phases and a ghost fluid approach to impose the jump conditions at the interface.

TL;DR: In this article, a series of experiments varying particle size, particle density, particle loading and flow Re has been conducted, and a mechanism of particle transport in wall turbulent flows has been proposed, in which the particles are transported by the bursting events of the wall regions.

TL;DR: In this article, the motion of solid particles near the wall in a turbulent boundary layer was investigated experimentally in a water flume by flow visualization techniques and by LDA, and the results showed that particle motion, as well as entrainment and deposition processes, are controlled by the action of coherent wall structures, which appear to be funnel vortices.
