Hyperstaticity and loops in frictional granular packings
Antoinette Tordesillas, Edward Lam, Philip T. Metzger
The hyperstatic nature of granular packings of perfectly rigid disks is analyzed algebraically and through numerical simulation. The elementary loops of grains emerge as a fundamen…
Craters Formed in Granular Beds by Impinging Jets of Gas
Philip T. Metzger, Robert C. Latta, Jason M. Schuler +1
When a jet of gas impinges vertically on a granular bed and forms a crater, the grains may be moved by several different mechanisms: viscous erosion, diffused gas eruption, bearing…
The Flow Of Granular Matter Under Reduced-Gravity Conditions
Paul G. Hofmeister, Jürgen Blum, Daniel Heißelmann
To gain a better understanding of the surfaces of planets and small bodies in the solar system, the flow behavior of granular material for various gravity levels is of utmost inter…
Laboratory studies of ice-particle collisions in Saturn's dense rings
Daniel Heißelmann, Jürgen Blum, Kristin Wolling
In this work, we report on microgravity studies of particle ensembles simulating ice-particle collisions in Saturn's dense main rings. We have developed an experimental method to s…
Quasistatic behavior and force transmission in packing of irregular polyhedral particles
Émilien Azema, Farhang Radjaï, Gilles Saussine
Dense packings composed of irregular polyhedral particles are investigated by numerical simulations under quasistatic triaxial compression. The Contact Dynamics method is used for…
Grain size dependence of barchan dune dynamics
C. Groh, N. Aksel, I. Rehberg +1
The dependence of the barchan dune dynamics on the size of the grains involved is investigated experimentally. Downsized barchan dune slices are observed in a narrow water flow tub…
