Abstract
This paper presents the force coefficients (added mass and damping) for a circular
cylinder oscillating horizontally in a uniformly stratified fluid of limited depth and
in a continuously stratified fluid with a smooth pycnocline. The frequency-dependent
added mass and damping are evaluated from Fourier transforms of the experimental
records of impulse response functions. The stratification is shown to have a strong
effect on the fluid–body interaction. It is found that, when the characteristic vertical
extent of stratification (depth of uniformly stratified fluid or pycnocline thickness)
decreases, the power radiated with internal waves is reduced and the maximum of
the frequency spectrum of wave power shifts toward lower frequency. The results of
experiments are compared with available theoretical predictions.
