Chirality tomography: measuring local helicity from trajectory linking
Manuel Noseda, Bernardo Luciano Español, Pablo Daniel Mininni +1
We present the first three-dimensional helicity maps of fully developed turbulence obtained through chirality tomography, a Lagrangian voxel-based method that reconstructs helicity…
Non-equilibrium formulation for inertial particles in turbulent swirling flows
Bernardo L. Español, Martin Obligado, Joachim Peinke +3
We study the dynamics of inertial particles in turbulence using datasets obtained from both direct numerical simulations and laboratory experiments of turbulent swirling flows. By…
Free surface topography of capillary flows using spatiotemporal phase shifting profilometry
Hélie de Miramon, Wladimir Sarlin, Axel Huerre +3
We present a novel experimental technique to characterize the free surface of capillary flows adapted from the Spatio-Temporal Phase Shifting Profilometry (ST-PSP) method introduce…
Discovery of propagating trains of oscillons over Faraday waves in a 1D experiment
Samantha Kucher, José Eduardo Wesfreid, Pablo Javier Cobelli
We report the discovery of highly localized structures traveling over a one-dimensional pattern of Faraday waves in a vertically-vibrated fluid layer confined in a thin annular cel…
Active grid turbulence anomalies through the lens of physics informed neural networks
SofÃa Angriman, Sarah E. Smith, Patricio Clark di Leoni +3
Active grids operated with random protocols are a standard way to generate large Reynolds number turbulence in wind and water tunnels. But anomalies in the decay and third-order sc…
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…
