Ensemble of Fixed Points in Multi-branch Shell Models of Turbulent Cascades
Flavio Tuteri, Sergio Chibbaro, Alexandros Alexakis
Stationary solutions of a shell model of turbulence defined on a dyadic tree topology are studied. Each node's amplitude is expressed as the product of amplitude multipliers associ…

Deterministic diffusion models for Lagrangian turbulence: robustness and encoding of extreme events
Tianyi Li, Flavio Tuteri, Michele Buzzicotti +2
Modeling Lagrangian turbulence remains a fundamental challenge due to its multiscale, intermittent, and non-Gaussian nature. Recent advances in data-driven diffusion models have en…

Fluctuations around Turbulence Models
Flavio Tuteri, Alexandros Alexakis, Sergio Chibbaro
Numerical simulations of turbulent flows at realistic Reynolds numbers generally rely on filtering out small scales from the Navier Stokes equations and modeling their impact throu…
