Stability theory suggests that the flow remains laminar for all flow rates, but in practice pipe flow becomes turbulent even at moderate speeds. This transition drastically affects the transport efficiency of mass, momentum, and heat. On the basis of the recent discovery of unstable traveling waves in computational studies of the Navier-Stokes equations and ideas from dynamical systems theory, a model for the transition process has been suggested. We report experimental observation of these traveling waves in pipe flow, confirming the proposed transition scenario and suggesting that the dynamics associated with these unstable states may indeed capture the nature of fluid turbulence."}],"volume":305,"author":[{"last_name":"Hof","first_name":"Björn","orcid":"0000-0003-2057-2754","id":"3A374330-F248-11E8-B48F-1D18A9856A87","full_name":"Björn Hof"},{"first_name":"Casimir","last_name":"Van Doorne","full_name":"van Doorne, Casimir W"},{"first_name":"Jerry","last_name":"Westerweel","full_name":"Westerweel, Jerry"},{"last_name":"Nieuwstadt","first_name":"Frans","full_name":"Nieuwstadt, Frans T"},{"last_name":"Faisst","first_name":"Holger","full_name":"Faisst, Holger"},{"first_name":"Bruno","last_name":"Eckhardt","full_name":"Eckhardt, Bruno"},{"first_name":"Håkan","last_name":"Wedin","full_name":"Wedin, Håkan"},{"full_name":"Kersweli, Richard R","first_name":"Richard","last_name":"Kersweli"},{"full_name":"Waleffe, Fabian","first_name":"Fabian","last_name":"Waleffe"}],"date_created":"2018-12-11T11:59:35Z","status":"public","day":"10","publisher":"American Association for the Advancement of Science","year":"2004","month":"09","citation":{"ieee":"B.
