Cornerstones are the Key Stones: Using Interpretable Machine Learning to Probe the Clogging Process in 2D Granular Hoppers
Jesse M. Hanlan, Sam Dillavou, Andrea J. Liu +1
The sudden arrest of flow by formation of a stable arch over an outlet is a unique and characteristic feature of granular materials. Previous work suggests that grains near the out…
Taut-Line Buzzers with Periodic Forcing
Jesse M. Hanlan, Douglas J. Durian
The time-dependent forcing and work per cycle required to drive sinusoidal spinning of a taut-line buzzer is analytically derived, both on and off resonance, from the nonlinear equ…
The Equation of Motion for Taut-Line Buzzers
Alexander J. Gerra, Courtney C. Jones, Sam Dillavou +4
Equations of motion are developed for the oscillatory rotation of a disk suspended between twisted strings kept under tension by a hanging mass, to which additional forces may be a…
Stochastic dynamics of granular hopper flows: a configurational mode controls the stability of clogs
David Hathcock, Sam Dillavou, Jesse M. Hanlan +2
Granular flows in small-outlet hoppers exhibit several characteristic but poorly understood behaviors: temporary clogs (pauses) where flow stops before later spontaneously restarti…
Twist and Measure: Characterizing the Effective Radius of Strings and Bundles under Twisting Contraction
Jesse M. Hanlan, Gabrielle E. Davis, Douglas J. Durian
We test the standard model for the length contraction of a bundle of strings under twist, and find deviation that is significantly greater than typically appreciated and that has a…
Aqueous foams in microgravity, measuring bubble sizes
Marina Pasquet, Nicolo Galvani, Olivier Pitois +9
The paper describes a study of wet foams in microgravity whose bubble size distribution evolves due to diffusive gas exchange. We focus on the comparison between the size of bubble…
