--- res: bibo_abstract: - Shear flows undergo a sudden transition from laminar to turbulent motion as the velocity increases, and the onset of turbulence radically changes transport efficiency and mixing properties. Even for the well-studied case of pipe flow, it has not been possible to determine at what Reynolds number the motion will be either persistently turbulent or ultimately laminar. We show that in pipes, turbulence that is transient at low Reynolds numbers becomes sustained at a distinct critical point. Through extensive experiments and computer simulations, we were able to identify and characterize the processes ultimately responsible for sustaining turbulence. In contrast to the classical Landau-Ruelle-Takens view that turbulence arises from an increase in the temporal complexity of fluid motion, here, spatial proliferation of chaotic domains is the decisive process and intrinsic to the nature of fluid turbulence.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Kerstin foaf_name: Avila, Kerstin foaf_surname: Avila - foaf_Person: foaf_givenName: David foaf_name: Moxey, David foaf_surname: Moxey - foaf_Person: foaf_givenName: Alberto foaf_name: de Lózar, Alberto foaf_surname: De Lózar - foaf_Person: foaf_givenName: Marc foaf_name: Avila, Marc foaf_surname: Avila - foaf_Person: foaf_givenName: Dwight foaf_name: Barkley, Dwight foaf_surname: Barkley - foaf_Person: foaf_givenName: Björn foaf_name: Björn Hof foaf_surname: Hof foaf_workInfoHomepage: http://www.librecat.org/personId=3A374330-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0003-2057-2754 bibo_doi: 10.1126/science.1203223 bibo_issue: '6039' bibo_volume: 333 dct_date: 2011^xs_gYear dct_publisher: American Association for the Advancement of Science@ dct_title: The onset of turbulence in pipe flow@ ...
