The formation of motion-induced dynamic adsorption layers of surfactants at the surface of
rising bubbles is a widely accepted phenomenon. Although their existence and formation …

This review focuses on the importance of air presence at hydrophobic solid surfaces for
wetting film rupture and kinetics of three phase contact formation. Affinity to air is a typical …

We present a collision model for particle-particle and particle-wall interactions in interface-
resolved simulations of particle-laden flows. Three types of interparticle interactions are …

The paper presents a model for particle–particle and particle–wall collisions during interface-
resolving numerical simulations of particle-laden flows. The accurate modelling of collisions …

We present a direct comparison between interface-resolved and one-way-coupled point-
particle direct numerical simulations (DNS) of gravity-free turbulent channel flow laden with …

Particle-wall collisions appear in many different processes of particle technology. During a
collision, different micro processes, such as friction, plastic deformation and adhesion can …

The dynamics of particle–particle collisions and the bouncing motion of a particle colliding
with a wall in a viscous fluid is numerically investigated. The dependence of the effective …

The effects of the particle collision model in a direct-forcing fictitious domain method on the
fluid and particle statistics of a fully developed turbulent channel flow laden with finite-size …

The canonical configuration of a solid particle bouncing on a wall in a viscous fluid is
considered here, focusing on rough particles as encountered in most of the laboratory …

Understanding the two-way interactions between finite-size solid particles and a wall-
bounded turbulent flow is crucial in a variety of natural and engineering applications …
