Behavior of confined granular beds under cyclic thermal loading
Pavel S. Iliev, Elena Giacomazzi, Falk K. Wittel +3
We investigate the mechanical behavior of a confined granular packing of irregular polyhedral particles under repeated heating and cooling cycles by means of numerical simulations…
Kelvin-Helmholtz instability of the Dirac fluid of charge carriers on graphene
Rodrigo C. V. Coelho, Miller Mendoza, Mauro M. Doria +1
We provide numerical evidence that a Kelvin-Helmholtz instability occurs in the Dirac fluid of electrons in graphene and can be detected in current experiments. This instability ap…
Granular front formation in free-surface flow of concentrated suspensions
A. Leonardi, M. Cabrera, F. K. Wittel +4
Granular fronts are a common yet unexplained phenomenon emerging during the gravity driven free-surface flow of concentrated suspensions. They are usually believed to be the result…
Particle-fluid-structure interaction for debris flow impact on flexible barriers
Alessandro Leonardi, Falk K. Wittel, Miller Mendoza +2
Flexible barriers are increasingly used for the protection from debris flow in mountainous terrain due to their low cost and environmental impact. However, a numerical tool for rat…
