Probing hydrodynamic fluctuation-induced forces with an oscillating robot
Steven W. Tarr, Joseph S. Brunner, Daniel Soto +1
We study the dynamics of an oscillating, free-floating robot that generates radially expanding gravity capillary waves at a fluid surface. In open water, the device does not self-p…
Water surface swimming dynamics in lightweight centipedes
Kelimar Diaz, Baxi Chong, Steven Tarr +2
Study of the locomotion of a centipede (L. forficatus) at the air-water interface reveals that it does not predominantly use its 14 leg pairs to locomote; unlike most swimmers whic…
Sand swimming lizard: sandfish
Ryan D. Maladen, Yang Ding, Adam Kamor +1
We use high-speed x-ray imaging to reveal how a small (~10cm) desert dwelling lizard, the sandfish (Scincus scincus), swims within a granular medium [1]. On the surface, the lizard…
Ripples and Shear Bands in Plowed Granular Media
Nick Gravish, Paul Umbanhowar, Daniel I. Goldman
Monodisperse packings of dry, air-fluidized granular media typically exist between volume fractions from = 0.585 to 0.64. We demonstrate that the dynamics of granular drag are s…
Dynamics of drag and force distributions for projectile impact in a granular medium
Massimo Pica Ciamarra, Antonio H. Lara, Andrew T. Lee +3
Our experiments and molecular dynamics simulations on a projectile penetrating a two-dimensional granular medium reveal that the mean deceleration of the projectile is constant and…
