  • Designing a more nonlinearly stable laminar flow via boundary manipulation 

    Rabin, SME; Caulfield, Colm-cille Patrick; Kerswell, Richard Rodney (Cambridge University PressJournal of Fluid Mechanics, 2013-12-04)
    We show how a fully nonlinear variational method can be used to design a more nonlinearly stable laminar shear flow by quantifying the effect of manipulating the boundary conditions of the flow. Using the example of plane ...

  • Multiple instability of layered stratifed plane Couette flow 

    Eaves, Thomas; Caulfield, Colm-cille Patrick (Cambridge University PressJournal of Fluid Mechanics, 2017-02-25)
    We present the linear stability properties and nonlinear evolution of two-dimensional plane Couette flow for a statically stable Boussinesq three-layer fluid of total depth 2$h$ between two horizontal plates driven at ...

  • Secondary instability and tertiary states in rotating plane Couette flow 

    Daly, CA; Schneider, Tobias M; Schlatter, Philipp; Peake, Nigel (Cambridge University PressJournal of Fluid Mechanics, 2014-11-14)
    Recent experimental studies have shown rich transition behaviour in rotating plane Couette ow (RPCF). In this paper we study the transition in supercritical RPCF theoretically by determination of equilibrium and periodic ...
