  • Turbulent Flow over a Flexible Wall Undergoing a Streamwise Traveling Wavy Motion 
    Shen, Lian; Zhang, Xiang; Yue, Dick K.P.; Triantafyllou, Michael S. (Cambridge University Press, 2003)
    Direct numerical simulation is used to study the turbulent flow over a smooth wavy wall undergoing transverse motion in the form of a streamwise travelling wave. The Reynolds number based on the mean velocity U of the ...
  • Three-dimensional flow structures and vorticity control in fish-like swimming 
    Zhu, Q.; Wolfgang, M.J.; Yue, D.K.P.; Triantafyllou, M.S. (Cambridge University Press, 2002)
    We employ a three-dimensional, nonlinear inviscid numerical method, in conjunction with experimental data from live fish and from a fish-like robotic mechanism, to establish the three-dimensional features of the flow ...
  • Vortex-induced vibrations of a cylinder with tripping wires 
    Hover, F.S.; Tvedt, H.; Triantafyllou, M.S. (Cambridge University Press, 2001)
    Thin wires are attached on the outer surface and parallel to the axis of a smooth circular cylinder in a steady cross-stream, modelling the effect of protrusions and attachments. The impact of the wires on wake properties, ...
  • Drag reduction in fish-like locomotion 
    Barrett, D.S.; Triantafyllou, M.S.; Yue, D.K.P.; Grosenbaugh, M.A.; Wolfgang, M.J. (Cambridge University Press, 1999)
    We present experimental force and power measurements demonstrating that the power required to propel an actively swimming, streamlined, fish-like body is significantly smaller than the power needed to tow the body straight ...
  • Mechanics of nonlinear short-wave generation by a moored near-surface buoy 
    Zhu, Q.; Liu, Y.; Tjavaras, A.A.; Triantafyllou, M.S.; Yue, D.K.P. (Cambridge University Press, 1999)
    We consider the nonlinear interaction problem of surface waves with a tethered near-surface buoy. Our objective is to investigate mechanisms for nonlinear short surface wave generation in this complete coupled wave-buoy-cable ...
