Breaking size-segregation waves and mobility feedback in dense granular avalanches.
Christophe Ancey, Kasper van der Vaart
Through experiments and discrete particle method (DPM) simulations we present evidence for the existence of a recirculating structure, that exists near the front of dense granular avalanches, and is known as a breaking size-segregation (BSS) wave. This is ...
2018Segregation of large particles in dense granular flows suggests a granular Saffman effect
Christophe Ancey, Kasper van der Vaart
We report on the scaling between the lift force and the velocity lag experienced by a single particle of different size in a monodisperse dense granular chute flow. The similarity of this scaling to the Saffman lift force in (micro-) fluids, suggests an in ...
2018Particle size-segregation in granular ows driven by a conveyor belt.
Christophe Ancey, Tomás Alfredo Trewhela Palacios, Kasper van der Vaart
Particle motion within the leading edge of bidisperse gravity-driven granular flows is affected by particle size segregation. Shear-induced segregation causes coarse particles to move towards the upper layers. Then, these are advected down to the tip regio ...
