• Two-dimensional flow of a viscous incompressible fluid past a rotationally-oscillating circular cylinder is investigated on the basis of Oseen's equations of motion. The cylinder is assumed to oscillate about its axis periodically. It is found that the solution is composed of a steady part and a periodic part, the latter of which is due to the periodic motion of the cylinder. The forces acting on the cylinder are calculated by two different methods; in one method the law of momentum conservation is applied to the flow region surrounded by a large control surface, while in the other the viscous stresses on the surface of the cylinder are integrated. The results by these two methods do not agree with each other, however, and there appears to exist something like Garstang's paradox. The flow field is calculated numerically at several instants of time in one period, and the flow patterns are shown graphically.
