A fundamental characteristic of granular flows is segregation on the basis of particle size or density. For bidisperse mixtures of particles, revolutions of the order of 10 produce a segregation ...

For example, analytical and numerical investigations have extended classical kinetic theory to systems where granular particles are immersed in a molecular gas, revealing how such interactions ...

Granular gases are systems that contain macroscopic particles in low density. Examples include cosmic dust, the rings around the planets Saturn, Uranus and Neptune and also clouds of dust on Earth.

Granular matter is all around us. Examples include sand, rice, nuts, coffee and even snow. These materials are made of solid particles that are large enough not to experience thermal fluctuations.

The complexity is further compounded by the transitions between different flow regimes. For example, a regime of moving particles can exhibit a mixed type of gas-liquid-solid behavior during flow, ...

The densest state of granular packings is defined by individual particles that form permanent contacts: The contacts can be monitored quantitatively by stress birefringence in both 2D and 3D. The ...

Bubble formation in granular systems exposed to gas flows, on the other hand, is important for procedures in which a gas is supposed to react as strongly as possible with catalyst particles.

Granular material state [jammed, glassy or fluid (Raihane et al., 2009)] is highly affected by the seismic input nature and the physical/mechanical properties of the particles. Several experimental ...

The detailed state of any particular one of these mixtures of particles is something you analyze using concepts that would've been familiar to Isaac Newton, 300-odd years ago: it's just a matter ...

Another type of bonding that can arise between granular particles results from the influence of tiny bridges of water (SN: 1/2/99, p. 6).
