| Abstract: | We present experimental data corresponding to a two-dimensional dense granular flow, namely, the gravitydriven
discharge of grains from a small opening in a silo. We study the local velocity field at the scale of single
grains at different places with the help of particle-tracking techniques. From these data, the velocity profiles can
be obtained and the validity of some long-standing approaches can be assessed. Moreover, the fluctuations of
the velocities are taken into consideration to characterize the features of the advective motion (due to the gravity
force) and the diffusive motion, which shows nontrivial behavior. |
