Instantons and the path to intermittency in turbulent flows
André Fuchs, Corentin Herbert, Joran Rolland +3
Processes leading to anomalous fluctuations in turbulent flows, referred to as intermittency, are still challenging. We consider cascade trajectories through scales as realizations…
Collapse of transitional wall turbulence captured using a rare events algorithm
Joran Rolland
This text presents one of the first successful applications of a rare events method for the study of multistability in a turbulent flow without stochastic energy injection. The tra…
Finite size analysis of a double crossover in transitional wall turbulence
Joran Rolland
This article presents the finite size analysis of two consecutive crossovers leading laminar-turbulent bands to uniform wall turbulence in transitional plane Couette flow. Direct n…
Formation of spanwise vorticity in oblique turbulent bands of transitional plane Couette flow, part 2: modelling and stability analysis
Joran Rolland
This article presents a modelling of the formation of spanwise vorticity in the turbulent streaks of the oblique bands and spots of transitional plane Couette flow. A functional mo…
Stochastic analysis of the time evolution of Laminar-Turbulent bands of plane Couette flow
Joran Rolland
This article is concerned with the time evolution of the oblique laminar-turbulent bands of transitional plane Couette flow under the influence of turbulent noise. Our study is foc…
Computing transition rates for the 1-D stochastic Ginzburg--Landau--Allen--Cahn equation for finite-amplitude noise with a rare event algorithm
Joran Rolland, Freddy Bouchet, Eric Simonnet
In this paper we compute and analyse the transition rates and duration of reactive trajectories of the stochastic 1-D Allen-Cahn equations for both the Freidlin-Wentzell regime (we…
