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…

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…

Assessment of the point-wise approach for the Turbulent Settling of finite-size particles
Francesco Battistaa, Sergio Chibbarob, Paolo Gualtieria
We study the settling of suspensions of relatively large particles with a diameter of the order of ten Kolmogorov scales and density slightly larger than the carrier fluid in stati…
