Taming Lagrangian Chaos with Multi-Objective Reinforcement Learning
Chiara Calascibetta, Luca Biferale, Francesco Borra +2
We consider the problem of two active particles in 2D complex flows with the multi-objective goals of minimizing both the dispersion rate and the energy consumption of the pair. We…
Heavy and light inertial particle aggregates in homogeneous isotropic turbulence: A study on breakup and stress statistics
Graziano Frungieri, Matthaus U. Baebler, Luca Biferale +1
The breakup of inertial, solid aggregates in an incompressible, homogeneous and isotropic three-dimensional turbulent flow is studied by means of a direct numerical simulation, and…
Multi-scale data reconstruction of turbulent rotating flows with Gappy POD, Extended POD and Generative Adversarial Networks
Tianyi Li, Michele Buzzicotti, Luca Biferale +3
Data reconstruction of rotating turbulent snapshots is investigated utilizing data-driven tools. This problem is crucial for numerous geophysical applications and fundamental aspec…
Optimal policies for Bayesian olfactory search in turbulent flows
Robin A. Heinonen, Luca Biferale, Antonio Celani +1
In many practical scenarios, a flying insect must search for the source of an emitted cue which is advected by the atmospheric wind. On the macroscopic scales of interest, turbulen…
Large-scale convective flow sustained by thermally active Lagrangian tracers
Lokahith Agasthya, Andreas Bartel, Luca Biferale +2
Non-isothermal particles suspended in a fluid lead to complex interactions -- the particles respond to changes in the fluid flow, which in turn is modified by their temperature ano…
Reconstructing Rayleigh-Bénard flows out of temperature-only measurements using nudging
Lokahith Agasthya, Patricio Clark Di Leoni, Luca Biferale
Nudging is a data assimilation technique that has proved to be capable of reconstructing several highly turbulent flows from a set of partial spatiotemporal measurements. In this s…
Non-equilibrium Ensembles for the three-dimensional Navier-Stokes Equations
Georgios Margazoglou, Luca Biferale, Massimo Cencini +2
At the molecular level fluid motions are, by first principles, described by time reversible laws. On the other hand, the coarse grained macroscopic evolution is suitably described…
