Dispersion is the desired disintegration of particle clusters down to their primary constituents
through the application of external forces, which overcome the interparticle attraction forces …

Memento, homo, qui pulvis est et pulverem reverteris. Genesis 3 Polvos serán, mas polvo
enamorado. Francisco de Quevedo The physics of granular materials in ambient gases is …

Molecular dynamics simulations are used to investigate the structure and mechanical
properties of a simple two-dimensional model of a cohesive granular material. Intergranular …

In this work, characterization of cohesion reduction at the particle as well as bulk scales is
addressed, including the investigation of analytical models to relate the properties at two …

The scaling up of fluidized beds has been purposefully pursued for more than 100 years.
Yet, over that time, scale-up tools have not significantly changed. Data analysis is typically a …

An increasing number of applications rely on the use of gas-fluidized beds of small particles
to enhance processes based on the mass/heat transfer between a gas and a solid. On the …

Solar technology has shown a keen interest in thermochemical storage to extend its
operational timespan beyond a daily basis. Thermochemical solutions are operated by fine …

We present measurements of the tensile strength as a function of the consolidation stress for
a set of fine cohesive powders (xerographic toners) of 12.7 μ m particle size and with a …

Fine powders are the cornerstone of new energy storage solutions to assist concentrated
solar power plants. Though, their ability to behave like fluid can be seriously affected at high …

We develop a novel theoretical model and experimental protocol to quantify the Granular
Bond number of a powder through fluidisation tests. Our proposed model utilises the …
