The study is related to the flexible circular cylinder in the Reynolds number range from 30 to 500. The shedding features of flexible cables are studied and general characteristics of vortex shedding are interpreted from diagnostic observations. The study has two objectives: (1) to observe and analyze the vortex shedding features characteristic of a flexible cable that is flow-excited into standing wave oscillations; and (2) to perform a diagnostic investigation of the spanwise shedding phenomenon when the vortex shedding is both dependent and independent of the oscillating motion.

This report presents the results on an extensive experimental investigation of the in-line and transverse forces acting on smooth and rough circular cylinders placed in oscillatory water flow at Reynolds numbers up to 700,000, Keulegan-Carpenter numbers up to 150, and relative roughnesses from 0.002 to 0.02. The drag and inertia coefficients have been determined through the use of the Fourier analysis and the least-squares method. The transverse force (lift) has been analyzed in terms of its maximum, semi-peak-to-peak, and root-mean-square values. In addition, the frequency of vortex shedding and the Strouhal number have been determined.
