Multi-sphere shape generator for DEM simulations of complex-shaped particles
Felix Buchele, Thorsten Pöschel, Patric Mueller
MSS is an algorithm to determine the radii and positions of spheres that fill a given volume. In the context of granular materials, MSS is a particle generator for DEM simulations…
Reciprocal swimming in viscoelastic granular hydrogels
Hongyi Xiao, Jing Wang, Achim Sack +2
We experimentally study a scallop-like swimmer with reciprocally flapping wings in a nearly frictionless, cohesive granular medium consisting of hydrogel spheres. Significant locom…
Rheology of dilute granular gas mixtures where the grains interact via a square shoulder and well potential
Kiwamu Yoshii, Satoshi Takada, Kosuke Kurosawa +1
We develop the rheology of a dilute granular gas mixture. Motivated by the interaction of charged granular particles, we assume that the grains interact via a square shoulder and w…
Hydrodynamic memory can boost enormously driven nonlinear diffusion and transport
Igor Goychuk, Thorsten Pöschel
Hydrodynamic memory force or Basset force is known since the 19th-century. Its influence on Brownian motion remains, however, mostly unexplored. Here, we investigate its role in no…
Size segregation and convection
Thorsten Poeschel, Hans J. Herrmann
The size segregation of granular materials in a vibrating container is investigated using Molecular Dynamics. We find that the rising of larger particles is accompanied by the exis…
Adaptive Evolutionary Optimization of Team Work
Volkhard Buchholtz, Thorsten Poeschel
We discuss a new optimization strategy, which considerably improves the effectivity of evolutionary algorithms applied to a certain class of optimization problems. The basic princi…
