Multiphase flows occurring in nature and in technological applications are often turbulent.
The large range of length scales and timescales in turbulent multiphase flows makes direct …

Kinetic equations arise in a wide variety of physical systems and efficient numerical methods
are needed for their solution. Moment methods are an important class of approximate …

We present an Asymptotic-Preserving 'all-speed'scheme for the simulation of compressible
flows valid at all Mach-numbers ranging from very small to order unity. The scheme is based …

We consider time-dependent (linear and nonlinear) Schrödinger equations in a
semiclassical scaling. These equations form a canonical class of (nonlinear) dispersive …

Substructures are ubiquitous in high resolution (sub-) millimeter continuum observations of
circumstellar discs. They are possibly caused by forming planets embedded in their disc. To …

Dilute gas-particle flows can be described by a kinetic equation containing terms for spatial
transport, gravity, fluid drag, and particle–particle collisions. However, the direct numerical …

Dilute gas–particle flows can be described by a kinetic equation containing terms for spatial

A two-dimensional numerical simulation of detonation in a reactive dispersed liquid droplet
cloud is performed with an Eulerian-Eulerian method. This study aims to investigate the …

In this paper, we present a new Eulerian multi-fluid modeling for dense sprays of
evaporating liquid droplets which is able to describe droplet coalescence and size …
