Abstract: An experimental study was carried out on a cylinder undergoing harmonic oscillation in line with an indident flow at Reynolds numbers of 27×103 and 54×103. Measurements were obtained of the ensemble-averaged cyclic pressure distribution, from which the cyclic in-line force was determined. It was found that the cyclic force could be approximated by a simple empirical relation based on a quasi-steady consideration of the flow. The quasi-steady drag coefficient was determined for various amplitude to diamater ratios from 0.4 to 2.4, and for a reduced velocity of up to 200. The base pressure coefficient was found to increase with the oscillation amplitude. © 1990.
