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. Visualization data are obtained using
digital particle image…

Forces are measured at both ends of rigid cylinders with span 60 cm, performing
transverse oscillations within an oncoming stream of water, at Reynolds number
Re ~3800. Forced harmonic motions and free vibrations of uniform and tapered
cylinders are studied.…
