The effects of fluid–particle and particle–particle interactions on the kinematic waves and
particle dynamics in a vertical pipe with continuous upward fluid flow are investigated. The …

When a thin tube is dipped into water, the water will ascend to a certain height, against the
action of gravity. While this effect, termed capillarity, is well known, recent experiments have …

Granular pipe flows are characterized by intermittent behavior and large, potentially
destructive solid fraction variations in the transport direction. By means of particle-based …

Grain flows through pipes are frequently found in various settings, such as in
pharmaceutical, chemical, petroleum, mining and food industries. In the case of size …

Gravitational flow of grains in pipes is frequently encountered in industry. When the grains
and pipes are size-constrained, granular flow may result in density waves consisting of …

We study theoretically dynamical phases of vortices in superconducting films with arrays of
obstacles. By performing a series of molecular-dynamics simulations and analytical …

Grain flows through pipes are frequently found in industry, such as in pharmaceutical,
chemical, petroleum, mining and food industries. In the case of size-constrained …

The dynamics of the density waves in gravity-driven flows of granular materials in narrow
pipes is studied experimentally. The experimental device consisted of a vertical glass pipe …

Grain flows through pipes are frequently found in various settings, such as in
pharmaceutical, chemical, petroleum, mining and food industries. In the case of size …

Generally speaking, modern manufacturing methods of high-technology materials rely
heavily on the utilization of granular materials. In many applications, the granular flow …
