In wide enough systems, plane Couette flow, the flow established between two parallel plates translating in opposite directions, displays alternatively turbulent and laminar oblique bands in a given range of Reynolds numbers R. We show that in periodic domains that contain a few bands, for given values of R and size, the orientation and the wavelength of this pattern can fluctuate in time. A procedure is defined to detect well-oriented episodes and to determine the statistics of their lifetimes… 
Patterns and dynamics in transitional plane Couette flow
Near transition, plane Couette flow takes the form of large-scale, oblique, and statistically steady alternating bands of turbulent and laminar flow. Properties of these flows are investigated using
On the decay of turbulence in plane Couette flow
Upon decreasing the Reynolds number, plane Couette flow first forms alternately turbulent and laminar oblique bands out of featureless turbulence below some upper threshold Ret. These bands exist
Ginzburg–Landau description of laminar-turbulent oblique band formation in transitional plane Couette flow
Abstract. Plane Couette flow, the flow between two parallel planes moving in opposite directions, is an example of wall-bounded flow experiencing a transition to turbulence with an ordered
On the decay of turbulence in plane Couette flow
The decay of turbulent and laminar oblique bands in the lower transitional range of plane Couette flow is studied by means of direct numerical simulations of the Navier-Stokes equations. We consider
Laminar-turbulent patterning in wall-bounded shear flows: a Galerkin model
On its way to turbulence, plane Couette flow–the flow between counter-translating parallel plates–displays a puzzling steady oblique laminar-turbulent pattern. We approach this problem via Galerkin
Turbulent spot growth in plane Couette flow: statistical study and formation of spanwise vorticity
This paper presents direct numerical simulations (DNSs) of the growth of turbulent spots in the transitional regime of plane Couette flow. A quantitative description of the growth process and of the
Turbulent bifurcations in intermittent shear flows: From puffs to oblique stripes
Localized turbulent structures such as puffs or oblique stripes are building blocks of the intermittency regimes in subcritical wall-bounded shear flows. These turbulent structures are investigated
Effects of spanwise system rotation on turbulent stripes in a plane Poiseuille flow
In the transitional channel flow, the large-scale intermittent structure of localised turbulence, which is called the turbulent stripe pattern, can be found in the form of stripe arrangement. The
Turbulent–laminar coexistence in wall flows with Coriolis, buoyancy or Lorentz forces
Abstract Direct numerical simulations of subcritical rotating, stratified and magneto-hydrodynamic wall-bounded flows are performed in large computational domains, focusing on parameters where

Long-wavelength modulation of turbulent shear flows
Computational study of turbulent laminar patterns in couette flow.
TLDR
Turbulent-laminar patterns near transition are simulated in plane Couette flow using an extension of the minimal-flow-unit methodology, finding three types of patterned states that correspond closely to observations in large-aspect-ratio experiments.
Dynamical systems and the transition to turbulence in linearly stable shear flows
TLDR
Evidence for this transition scenario in plane Couette flow and pressure-driven pipe flow depends sensitively on initial conditions and the turbulent state is not persistent but has an exponential distribution of lifetimes.
Formation of turbulent patterns near the onset of transition in plane Couette flow
The formation of turbulent patterns in plane Couette flow is investigated near the onset of transition, using numerical simulation in a very large domain of size 800 h × 2 h × 356 h. Based on a

A self-sustaining process conjectured to be generic for wall-bounded shear flows is investigated. The self-sustaining process consists of streamwise rolls that redistribute the mean shear to create
Deviations from linear theory for fluctuations below the supercritical primary bifurcation to electroconvection
TLDR
Experimental observations of nonlinear interactions between thermally driven fluctuations in dissipative nonlinear nonequilibrium systems lead to deviations from mean-field theory as a supercritical primary bifurcation is approached.

TLDR
The effects of additive Gaussian white noise on the onset of Rayleigh-Benard convection are studied by means of a phenomenological model, the stochastic Swift-Hohenberg equation, and an earlier analytic approximation scheme for calculating the response to a time-dependent Rayleigh number is applied.
