  • 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 ...
  • Anderson, J. M.; Streitlien, K.; Barrett, D.S.; Triantafyllou, M.S. (Cambridge University Press, 1998)
    Thrust-producing harmonically oscillating foils are studied through force and power measurements, as well as visualization data, to classify the principal characteristics of the flow around and in the wake of the foil. ...
  • Triantafyllou, Michael S.; Bodson, Marc; Athans, Michael (Institute of Electrical and Electronic Engineers, 1983)
    The estimation of the heave, pitch, roll, sway, and yaw motions of a DD-963 destroyer is studied, using Kalman filtering techniques, for application in VTOL aircraft landing. The governing equations are obtained from ...
  • Triantafyllou, Michael S.; Techet, Alexandra H.; Hover, Franz S. (Institute of Electrical and Electronic Engineers, 2004-07)
    Significant progress has been made in understanding some of the basic mechanisms of force production and flow manipulation in oscillating foils for underwater use. Biomimetic observations, however, show that there is a ...
  • Triantafyllou, Michael S .; Grosenbaugh, Mark A. (Institute of Electrical and Electronic Engineers, 1991)
    Presented in this paper is a robust control scheme for controlling systems with time delays. The scheme is based on the Smith controller and the LQG/LTR (Linear Quadratic Gaussian/Loop Transfer Recovery) methodology. ...
  • 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 ...
  • 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 ...
  • 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, ...
  • Techet, A. H.; Hover, F. S.; Triantafyllou, M.S. (Cambridge University Press, 1998)
    Visualization studies of the flow behind an oscillating tapered cylinder are performed at Reynolds numbers from 400 to 1500. The cylinder has taper ratio 40:1 and is moving at constant forward speed U while being forced ...
