Rainer Diaz-Bone,Christoph Weischerive behaviour of the grains, and the diflusion coefficient. Positron Emission Particle Tracking has been used to follow the motion of a single grain within an experimental cell, and preliminary measurements of the granular temperature of a dilute three-dimensional granular gas have been made for the first time.

The direction of the transport may also depend on the coefficient of restitution. We give a simple explanation for the mechanism responsible for determining the direction of the granular flow.

Vorbemerkung: Zum Anliegen dieses Bucheslow. As a result the interparticle collisions will tend to increase density gradient, leading to formation of gaps, sharp edges, or narrow ringlets. Numerical 3-dimensional collisional simulations including satellite perturbations can capture the essence of this process.

Energy Loss and Aggregation Processes in Low Speed Collisions of Ice Particles Coated with Frosts orhich sticking contacts have been observed. These results are compared with a few other similar measurements, and with theoretical models for energy loss in collisions. Specific applications to the dynamics of Saturn’s rings and to the formation of planetesimals in the early solar nebula, which motivated these studies, are also discussed.
