Drift of interfaces in forced stably-stratified turbulence and the role of vertically-sheared helical structures
Niccolò Cocciaglia, Luca Biferale, Fabio Bonaccorso +1
Experimental investigations of forced stably stratified turbulence (SST) have shown that the step-like density profile, made of well-mixed density layers and sharp interfaces alter…
Inferring the Turbulent Breakup of Colloidal Aggregates Using Graph Neural Networks
Michele Buzzicotti, Massimo Cencini, Giulio Cimini +2
Solid aggregates in turbulent suspensions may break under the action of shear stresses. We explore the use of Graph Neural Networks (GNN) to infer aggregate fragmentation once the…
Long-time evolution of density layers and interfaces in forced stably-stratified flows
Niccolo Cocciaglia, Fabio Bonaccorso, Alessandra Sabina Lanotte +1
Stably stratified fluids subject to sustained forcing are known to develop step-like density "staircases", where nearly homogeneous layers alternate with thin interfaces of strong…
Topological Pathways to Two-Dimensional Quantum Turbulence
Riccardo Panico, Giorgio Ciliberto, Giovanni Italo Martone +4
We present a combined experimental and theoretical investigation of the formation and decay kinetics of vortices in two dimensional, compressible quantum turbulence. We follow the…
