U-Net based particle localization in granular experiments: Accuracy limits and optimization
Fahad Puthalath, Matthias Schröter, Nicoletta Sanvitale +2
Identifying the positions of granular particles from experimental images is often complicated by their partial overlap in two dimensional projections. Uneven backgrounds and inhomo…
Towards probing velocity distributions in dense granular matter: Utilizing Fiber Bragg Gratings
Marlo Kunzner, Luis Henriques, Fahad Puthalath +8
Granular gases are commonly characterized through their velocity distribution, which provides access to the granular temperature. In experiments, velocity distributions are typical…
Velocity Distribution of a Homogeneously Cooling Granular Gas
Peidong Yu, Matthias Schröter, Matthias Sperl
In contrast to molecular gases, granular gases are characterized by inelastic collisions and require therefore permanent driving to maintain a constant kinetic energy. The kinetic…
Acoustic Waves in Granular Packings at Low Confinement Pressure
Karsten Tell, Christoph Dreißigacker, Alberto Chiengue Tchapnda +2
Elastic properties of a granular packing show nonlinear behavior determined by its discrete structure and nonlinear inter-grain force laws. Acoustic waves show a transition from co…
Monitoring Three-Dimensional Packings in Microgravity
Peidong Yu, Stefan Frank-Richter, Alexander Borngen +1
We present results from experiments with granular packings in three dimensions in microgravity as realized on parabolic flights. Two different techniques are employed to monitor th…
