Rotating-drum flows span a variety of research areas, ranging from physics of granular
matter through hydrodynamics of suspensions to pure liquid coating flows. Recent years …

It is difficult to observe directly the particle motion inside a dense granular flow or a fluid-
particle flow because of the existence of surrounding particles. MRI (Magnetic Resonance …

The use of a Young's modulus lower than its true value is commonly adopted in numerical
studies based on the discrete element method (DEM), in order to reduce the computational …

Measuring velocity fields plays a crucial role in investigating the dynamics of granular flows,
which can improve the modeling of hazardous geophysical flows (eg avalanches and debris …

The physics of granular matter is one of the big questions in science. Granular matter serves
as a prototype of collective systems far from equilibrium and fundamental questions remain …

This work assesses the accuracy of the discrete element method (DEM) for the simulation of
solids mixing using non‐intrusive Lagrangian radioactive particle tracking data, and …

To investigate the particle motion in the flighted rotating drum (FRD), a laboratory drum with
four rectangular flights is horizontally arranged and filled with plastic particles in this work …

Positron Emission Particle Tracking (PEPT) is a technique which allows the three-
dimensional, internal dynamics of opaque systems to be imaged with high temporal and …

This paper presents a numerical study on the flow behaviours of granular materials in a
rotating drum based on the Eulerian-formulation finite element method (Eulerian FEM). The …

This paper reports the measurement of granular temperature in gas-fluidized beds using
magnetic resonance. Experiments were performed using 0.5 and 1.2 mm diameter particles …
