Turbulent dispersed multiphase flows are common in many engineering and environmental
applications. The stochastic nature of both the carrier-phase turbulence and the dispersed …

In this paper, recent advances in the discrete-element method (DEM) for describing motion,
deposition, agglomeration or aggregation of a large number of adhesive spherical particles …

The COVID-19 pandemic has strikingly demonstrated how important it is to develop
fundamental knowledge related to the generation, transport and inhalation of pathogen …

The hydraulic transport of coarse particles in a vertical pipe is simulated in this work and the
influences of different mechanisms of the fluid-particle interactions on the liquid-solid flow …

Simple dimensional arguments are used in establishing three different regimes of particle
time scale, where explicit expression for particle Reynolds number and Stokes number are …

In the framework of the IAVCEI (International Association of Volcanology and Chemistry of
the Earth Interior) intercomparison study on volcanic plume models, we present three …

A new fluid-dynamic model is developed to numerically simulate the non-equilibrium
dynamics of polydisperse gas–particle mixtures forming volcanic plumes. Starting from the …

Accurate momentum coupling model is vital to simulation of dispersed multiphase flows. The
overall force exerted on a particle is divided into four physically meaningful contributions, ie …

In this work we introduce an Eulerian–Eulerian formulation for gravity currents driven by
inertial particles. The model is based on the equilibrium Eulerian approach and on an …

Debris clouds provide an important visual signature of tornadoes and can potentially
significantly affect the wind structure, damage potential, and Doppler radar measurements of …
