Journal ArticleDOI
Turbulence transition in pipe flow
TL;DR: Pipe flow is a prominent example among the shear flows that undergo transition to turbulence without mediation by a linear instability of the laminar profile as discussed by the authors, which can consistently be explained on the assumption that the turbulent state corresponds to a chaotic saddle in state space.
Journal ArticleDOI
Crowd synchrony on the Millennium Bridge
TL;DR: This approach should help engineers to estimate the damping needed to stabilize other exceptionally crowded footbridges against synchronous lateral excitation by pedestrians by adapting ideas originally developed to describe the collective synchronization of biological oscillators such as neurons and fireflies.
Journal ArticleDOI
Experimental Observation of Nonlinear Traveling Waves in Turbulent Pipe Flow
Björn Hof,Casimir W. H. van Doorne,Jerry Westerweel,Frans T. M. Nieuwstadt,Holger Faisst,Bruno Eckhardt,Håkan Wedin,Richard R Kerswell,Fabian Waleffe +8 more
TL;DR: Experimental observation of unstable traveling waves in pipe flow is reported, confirming the proposed transition scenario and suggesting that the dynamics associated with these unstable states may indeed capture the nature of fluid turbulence.
Journal ArticleDOI
Traveling waves in pipe flow
Holger Faisst,Bruno Eckhardt +1 more
TL;DR: A family of three-dimensional traveling waves for flow through a pipe of circular cross section that provide a skeleton for the formation of a chaotic saddle that can explain the intermittent transition to turbulence and the sensitive dependence on initial conditions in this shear flow.
Journal ArticleDOI
Edge of chaos in a parallel shear flow.
TL;DR: It is found that the surface of the edge of chaos coincides with the stable manifold of a periodic orbit, whereas at higher Reynolds numbers it is the stable set of a higher-dimensional chaotic object.
