N2 - A new form of dynamic response for a flexibly mounted, rotating cylinder in a current, as observed in experiments, has been investigated through 2-D, laminar CFD. Orbital response of opposite rotation to that of the cylinder and with amplitudes of several diameters can occur with a maximum at α = 0.3, where α is the ratio of current velocity to rotation speed of the cylinder surface. Instantaneous flows and forces for this α value are related to those for a nonresponding cylinder but it is shown that the forcing is far from quasi-steady and is due to rapidly changing wake structures during part of a cycle. © 2001 Academic Press.
