Broken mirror symmetry of tracer's trajectories in turbulence
Sofía Angriman, Pablo J. Cobelli, Mickaël Bourgoin +3
Topological properties of physical systems play a crucial role in our understanding of nature, yet their experimental determination remains elusive. We show that the mean helicity,…
Vector potential-based MHD solver for non-periodic flows using Fourier continuation expansions
Mauro Fontana, Pablo D. Mininni, Oscar P. Bruno +1
A high-order method to evolve in time electromagnetic and velocity fields in conducting fluids with non-periodic boundaries is presented. The method has a small overhead compared w…
Connecting Large-Scale Velocity and Temperature Bursts with Small-Scale Intermittency in Stratified Turbulence
Fabio Feraco, Raffaele Marino, Leonardo Primavera +13
Non-Gaussian statistics of large-scale fields are routinely observed in data from atmospheric and oceanic campaigns and global models. Recent direct numerical simulations (DNSs) sh…
Turbulence generation by large-scale extreme vertical drafts and the modulation of local energy dissipation in stably stratified geophysical flows
Raffaele Marino, Fabio Feraco, Leonardo Primavera +4
We observe the emergence of strong vertical drafts in direct numerical simulations of the Boussinesq equations in a range of parameters of geophysical interest. These structures, w…
Extraction of invariant manifolds and application to turbulence with a passive scalar
Nicolas E. Sujovolsky, Pablo D. Mininni
The reduction of dimensionality of physical systems, specially in fluid dynamics, leads in many situations to nonlinear ordinary differential equations which have global invariant…
Markov property of Lagrangian turbulence
A. Fuchs, M. Obligado, M. Bourgoin +3
Based on direct numerical simulations with point-like inertial particles, with Stokes numbers, , , and , transported by homogeneous and isotropic turbulen…
