Phys. Rev. E 69, 056306 (2004) [4 pages]Coherent structures in boundary layers of Rayleigh-Bénard convectionReceived 15 October 2003; revised 9 January 2004; published 21 May 2004 A coherent structure is revealed experimentally by a dyeing technique in the boundary layer of Rayleigh-Bénard convection in water. Dye accumulates in streaks aligned with the mean flow. Possible mechanisms for the formation of these streaks are discussed. © 2004 The American Physical Society URL:
