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
Exact coherent structures in pipe flow: travelling wave solutions
Håkan Wedin,Richard R Kerswell +1 more
TL;DR: In this paper, three-dimensional travelling wave solutions for pressure-driven fluid flow through a circular pipe are found for wall-bounded shear flows using a constructive continuation procedure based on key physical mechanisms.
Journal ArticleDOI
Invariant recurrent solutions embedded in a turbulent two-dimensional Kolmogorov flow
TL;DR: In this paper, the authors consider long-time simulations of two-dimensional turbulence body forced by on the torus with the purpose of extracting simple invariant sets or "exact recurrent flows" embedded in this turbulence.
Journal ArticleDOI
Oscillatory internal shear layers in rotating and precessing flows
TL;DR: In this paper, the authors present a direct numerical solution of a particular inertial oscillation, the so-called spin-over mode, in spherical geometry and demonstrate that the oscillatory Ekman layer breaks down at k30" latitude, and that this breakdown spawns internal shear layers.
Journal ArticleDOI
On the internal shear layers spawned by the critical regions in oscillatory Ekman boundary layers
TL;DR: In this article, it was shown that the Ekman boundary layer scalings associated with small oscillatory flows in a rapidly rotating system are well known to break down at critical latitudes.
