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…
Active grid turbulence anomalies through the lens of physics informed neural networks
Sofía 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…
Preferential concentration of free-falling heavy particles in turbulence
Florencia Falkinhoff, Martin Obligado, Mickaël Bourgoin +1
We present a sweep-stick mechanism for heavy particles transported by a turbulent flow under the action of gravity. Direct numerical simulations show that these particles preferent…
Velocity and acceleration statistics in particle-laden turbulent swirling flows
Sofía Angriman, Pablo D. Mininni, Pablo J. Cobelli
We present a comparison of different particles' velocity and acceleration statistics in two paradigmatic turbulent swirling flows: the von Kármán flow in a laboratory experiment, a…
Statistics of single and multiple floaters in experiments of surface wave turbulence
Nicolás F. Del Grosso, Lucía M. Cappelletti, Nicolás E. Sujovolsky +2
We present laboratory experiments of surface wave turbulence excited by paddles in the deep water regime. The free surface is seeded with buoyant particles that are advected and di…
Vertical dispersion of Lagrangian tracers in fully developed stably stratified turbulence
Nicolas E. Sujovolsky, Pablo D. Mininni
We study the effect of different forcing functions and of the local gradient Richardson number Rig on the vertical mixing of Lagrangian tracers in stably stratified turbulence unde…
