Experiments and simulations lend mounting evidence for the edge state hypothesis on subcritical transition to turbulence, which asserts that simple states of fluid motion mediate between laminar and turbulent shear flow as their stable manifolds separate the two in state space. In this Letter we describe flows homoclinic to a time-periodic edge state that display the essential properties of turbulent bursting. During a burst, vortical structures and the associated energy dissipation are highly…

Recent studies have shown that in transitional wall-bounded shear flows without linear instability of a laminar state the boundary between laminar and turbulent flows can be numerically identified in
Recent studies on wall-bounded shear flow have emphasized the significance of the stable manifold of simple nonlinear invariant solutions to the Navier-Stokes equation in the formation of the
Geometry of transient chaos in streamwise-localized pipe flow turbulence
In pipes and channels, the onset of turbulence is initially dominated by localized transients, which lead to sustained turbulence through their collective dynamics. In the present work, we study the
Heteroclinic and homoclinic connections in a Kolmogorov-like flow.
This study compute an extensive network of dynamical connections between such solutions in a weakly turbulent quasi-two-dimensional Kolmogorov flow that lies in the inversion-symmetric subspace and provides strong evidence that the associated homoclinic tangle forms the chaotic repeller that underpins transient turbulence in the symmetric sub space.
Heteroclinic path to spatially localized chaos in pipe flow
In shear flows at transitional Reynolds numbers, localized patches of turbulence, known as puffs, coexist with the laminar flow. Recently, Avila et al. (Phys. Rev. Lett., vol. 110, 2013, 224502)
Layer formation in horizontally forced stratified turbulence: connecting exact coherent structures to linear instabilities
We consider turbulence in a stratified ‘Kolmogorov’ flow, driven by horizontal shear in the form of sinusoidal body forcing in the presence of an imposed background linear stable stratification in
Unstable periodic orbits in plane Couette flow with the Smagorinsky model
We aim at a description of the logarithmic velocity profile of wall turbulence in terms of unstable periodic orbits (UPOs) for plane Couette flow with a Smagorinsky-type eddy viscosity model. We
Periodic orbits near onset of chaos in plane Couette flow.
A symbolic dynamics for the orbits is introduced and it is shown that the ones that exist fall into the universal sequence described by Metropolis, Stein and Stein for unimodal maps.
The onset of transient turbulence in minimal plane Couette flow
The onset of transient turbulence in minimal plane Couette flow has been identified theoretically as homoclinic tangency with respect to a simple edge state for the Navier–Stokes equation, i.e., the
Bursting and critical layer frequencies in minimal turbulent dynamics and connections to exact coherent states
The dynamics of the turbulent near-wall region is known to be dominated by coherent structures. These near-wall coherent structures are observed to burst in a very intermittent fashion, exporting


The Dynamics of Bursting Process in Wall Turbulence
We have examined bursting processes observed in turbulent channel flow by direct numerical simulation of the incompressible Navier-Stokes equations in a minimal flow unit. A traveling wave solution
Dynamical systems and the transition to turbulence in linearly stable shear flows
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.

In his landmark paper of 1883, Reynolds addressed the question of why the fluid motion along a pipe changes from a laminar to a turbulent state at modest flow rates. His discoveries have remained a

Finite-amplitude solutions of plane Couette flow are discovered. They take a steady three-dimensional form. The solutions are obtained numerically by extending the bifurcation problem of a circular
