Phys. Rev. Lett. 94, 014502 (2005) [4 pages]Computational Study of Turbulent Laminar Patterns in Couette FlowReceived 29 March 2004; published 7 January 2005 Turbulent-laminar patterns near transition are simulated in plane Couette flow using an extension of the minimal-flow-unit methodology. Computational domains are of minimal size in two directions but large in the third. The long direction can be tilted at any prescribed angle to the streamwise direction. Three types of patterned states are found and studied: periodic, localized, and intermittent. These correspond closely to observations in large-aspect-ratio experiments. © 2005 The American Physical Society URL:
