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
Three-dimensional traveling waves in a square duct.
TL;DR: A nonlinear streamwise traveling-wave solution is obtained by homotopy for square duct flow that resembles the transitional flow structures observed in previous simulations.
Journal ArticleDOI
A new nonlinear vortex state in square-duct flow
TL;DR: In this article, a nonlinear travelling wave solution for a flow through an isothermal square duct is discovered by a continuation approach in parameter space, starting from a case where the fluid is heated internally.
AM05-22-014 Exact Coherent Structures in Pipe Flow : Travelling Wave Solutions
Håkan Wedin,Rich Kerswell +1 more
TL;DR: In this paper, three-dimensional travelling wave solutions are found for pressure-driven fluid flow through a circular pipe, which consist of three well-defined flow features -streamwise rolls and streaks which dominate and streamwise-dependent wavy structures.
