A probabilistic protocol for the assessment of transition and control
Anton Pershin, Cedric Beaume, Steven M. Tobias
Transition to turbulence dramatically alters the properties of fluid flows. In most canonical shear flows, the laminar flow is linearly stable and a finite-amplitude perturbation i…

Dynamics of spatially localized states in transitional plane Couette flow
Anton Pershin, Cedric Beaume, Steven M. Tobias
Unsteady spatially localized states such as puffs, slugs or spots play an important role in transition to turbulence. In plane Couette flow, steady versions of these states are fou…

Emergence of stochastic dynamics in plane Couette flow
Rishabh Gvalani, Cédric Beaume
Spatially localized states play an important role in transition to turbulence in shear flows (Kawahara, Uhlmann & van Veen, Annu. Rev. Fluid Mech. 44, 203 (2012)). Despite the fact…
