The direct enstrophy cascade of two-dimensional soap film flows
Mike Rivera, Hussein Aluie, Robert Ecke
We investigate the direct enstrophy cascade of two-dimensional decaying turbulence in a flowing soap film channel. We use a coarse-graining approach that allows us to resolve the n…
Fragility and hysteretic creep in frictional granular jamming
M. M. Bandi, M. K. Rivera, F. Krzakala +1
The granular jamming transition is experimentally investigated in a two-dimensional system of frictional, bi-dispersed disks subject to quasi-static, uniaxial compression at zero g…
Mixing in stratified gravity currents: Prandtl mixing length
Philippe Odier, Jun Chen, Michael K. Rivera +1
Shear-induced vertical mixing in a stratified flow is a key ingredient of thermohaline circulation. We experimentally determine the vertical flux of momentum and density of a force…
Eulerian and Lagrangian velocity statistics in weakly forced two-dimensional turbulence
Michael K. Rivera, Robert E. Ecke
We present statistics of velocity fluctuations in both the Lagrangian and Eulerian frame for weakly driven two-dimensional turbulence. We find that simultaneous inverse energy and…
Lagrangian statistics and coherent structures in two-dimensional turbulence
Michael K. Rivera, W. Brent Daniel, Robert E. Ecke
Measurements of Lagrangian single-point and multiple-point statistics in a quasi-two-dimensional stratifed layer system are reported. The system consists of a layer of salt water o…
Spontaneous spirals in vibrated granular chains
R. E. Ecke, Z. A. Daya, M. K. Rivera +1
We present experimental measurements on the spontaneous formation of compact spiral structures in vertically-vibrated granular chains. Under weak vibration, when the chain is quasi…
