Simulating isothermal aging of snow
Roman Vetter, Stephan Sigg, Herman M. Singer +3
A Monte Carlo algorithm to simulate the isothermal recrystallization process of snow is presented. The snow metamorphism is approximated by two mass redistribution processes, surfa…
The Role of Contact Angle Hysteresis for Fluid Transport in Wet Granular Matter
Roman Mani, Ciro Semprebon, Dirk Kadau +3
The stability of sand castles is determined by the structure of wet granulates. Experimental data about the size distribution of fluid pockets are ambiguous about their origin. We…
Microscopic mechanism for the shear-thickening of non-Brownian suspensions
Nicolas Fernandez, Roman Mani, David Rinaldi +7
We propose a simple model, supported by contact-dynamics simulations as well as rheology and friction measurements, that links the transition from continuous to discontinuous shear…
Liquid migration in sheared unsaturated granular media
Roman Mani, Dirk Kadau, Hans J. Herrmann
We show how liquid migrates in sheared unsaturated granular media using a grain scale model for capillary bridges. Liquid is redistributed to neighboring contacts after rupture of…
Fluid depletion in shear bands
Roman Mani, Dirk Kadau, Dani Or +1
How does pore liquid reconfigure within shear bands in wet granular media? Conventional wisdom predicts that liquid is drawn into dilating granular media. We, however, find a deple…
Particle and particle pair dispersion in turbulence modeled with spatially and temporally correlated stochastic processes
Thomas Burgener, Dirk Kadau, Hans Jürgen Herrmann
In this paper we present a new model for modeling the diffusion and relative dispersion of particles in homogeneous isotropic turbulence. We use an Heisenberg-like Hamiltonian to i…
