The flow induced by a cylinder, with a small amplitude sinusoidal surface perturbation, torsionally oscillating in an unbounded fluid is considered. In particular the Taylor number is close to its critical value, and the interaction between the forced and the natural solutions is investigated for a number of different wavelengths of surface distortion.
