The simplicity of hard spheres as a model system is deceptive. Although the particles
interact solely through volume exclusion, that nevertheless suffices for a wealth of static and …

We present an overview of recent advances in the understanding of foam structure and
energy and their dependence on liquid volume fraction. We consider liquid foams in …

Uncovering grain-scale mechanisms that underlie the disorder–order transition in
assemblies of dissipative, athermal particles is a fundamental problem with technological …

The paper presents two Direct Numerical Simulations of bubble swarms in a vertical
turbulent channel flow and is intended as a complement to the companion paper, Santarelli …

The paper presents results of Direct Numerical Simulations of bubbles rising in a vertical
channel flow configuration for a dilute and for a denser swarm. The bubbles, considered as …

In this paper an immersed boundary method with semi-implicit fluid–solid coupling for
mobile particles of arbitrary density ratio is developed. The new scheme does not require …

The paper introduces a time scheme for an immersed boundary method which enables the
efficient, phase-resolving simulation of very light particles in viscous flow. A simple …

This paper analyses the turbulent kinetic energy budget for bubble swarms in a turbulent
channel flow configuration with realistic density difference. The data employed result from …

Granular crystallisation is an important phenomenon whereby ordered packing structures
form in granular matter under vibration. However, compared with the well-developed …

The mesostructure of ordered arrays of anisotropic nanoparticles is controlled by a
combination of packing constraints and interparticle interactions, two factors that are strongly …
