Effect of local flow geometry on particle pair dispersion angle
B. L. Español, M. Noseda, P. J. Cobelli +1
We combine experiments in a von Kármán flow with numerical simulations of Taylor-Green and homogeneous and isotropic turbulence to study the effect of the local flow geometry on pa…

Turbulence unsteadiness drives extreme clustering
Florencia Zapata, Sofía Angriman, Amélie Ferran +3
We show that the unsteadiness of turbulence has a drastic effect on turbulence parameters and in particle cluster formation. To this end we use direct numerical simulations of part…

Conformal invariance in water-wave turbulence
M. Noseda, P. J. Cobelli
We experimentally investigate the statistics of zero-height isolines in gravity wave turbulence as physical candidates for conformal invariant curves. We present direct evidence th…
