Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 2005. / Includes bibliographical references (p. 99-101). / A series of Multi-Frequency cable vibration experiments at Reynolds number 7600 were carried out at the MIT Tow Tank using the Virtual Cable Towing Apparatus (VCTA). Motions observed in a Direct Numerical Simulation of a flexible cylinder in a shear current were imposed on the VCTA and force measurements taken. Results showed a good agreement between the RMS lift coefficients of experiment and simulation. Complex Demodulation Analysis revealed significant lift force phase modulations. This analysis also showed that to a large extent the 3-dimensional behavior of the DNS was captured by the 2-d experiment in regions of low inflow, and to a lesser extent in regions of high inflow. Applications of results to future vortex induced vibration force models are discussed. / by Andrew Wiggins. / S.M.
