Digging through 2D densely-packed coarse granular media as a critical phenomenon
Guo-Jie Jason Gao, Fu-Ling Yang, Michael C. Holcomb +1
We create a mechanical digger able to move within 2D densely-packed granular media, in a manner intrinsically different from the existing biomimic diggers. The characteristics of o…
Enhanced flow rate by the concentration mechanism of Tetris particles when discharged from a hopper with an obstacle
Guo-Jie Jason Gao, Fu-Ling Yang, Michael C. Holcomb +1
We apply a holistic 2D Tetris-like model, where particles move based on prescribed rules, to investigate the flow rate enhancement from a hopper. This phenomenon was originally rep…
Studying the Kinetics of a Self-propelled Cruiser in 2D Granular Media under Gravity
Guo-Jie J. Gao
We propose a cruiser able to move in a granular medium made of nearly 50-50 bidisperse dissipative particles under gravity. The cruiser has a circular shape with a square indentati…
Understanding the Local Flow Rate Peak of a Hopper Discharging Discs through an Obstacle Using a Tetris-like Model
Guo-Jie J. Gao, Jerzy Blawzdziewicz, Michael C. Holcomb +1
Placing a round obstacle above the orifice of a flat hopper discharging uniform frictional discs has been experimentally and numerically shown in the literature to create a local p…
A Tetris-like Model Showing a Universal Enhanced Flow Rate of a Hopper Discharging Hard Discs Through an Adjustable Inclusion
Guo-Jie Jason Gao
In the literature, placing an inclusion near the orifice of a hopper, containing disc particles, has been experimentally and numerically reported to locally enhance the gravity-dri…
Geometrical families of mechanically stable granular packings
Guo-Jie Gao, Jerzy Blawzdziewicz, Corey S. O'Hern
We enumerate and classify nearly all of the possible mechanically stable (MS) packings of bidipserse mixtures of frictionless disks in small sheared systems. We find that MS packin…
