Abstract In 2007 Fernandes et al. reported a surprising delay of the onset of instabilities for freely rising cylinders of aspect ratio (χ=diameter/thickness of the cylinder) 10 and more. At Reynolds numbers at which instabilities develop in the wake of the same body kept fixed, the path was still found to be vertical and the wake axisymmetric. In this paper, we explain this delay by investigating numerically the transition scenario of the solid–fluid system represented by the freely moving… CONTINUE READING
