ECCENTRIC OSCILLATIONS OF A CIRCULAR-CYLINDER IN A VISCOUS-FLUID

We consider the fluid motion induced when a circular cylinder performs small-amplitude oscillations about an axis parallel to a generator to which it is rigidly attached as in Fig 1(a). In common with other fluid flows dominated by oscillatory motion, a time-independent, or steady streaming develops, and this is the focus of our attention. In particular we relate our results, qualitatively, to the observations that have been made in experiments.
