Abstract
A finite difference solution is presented for 2D laminar unsteady flow around a circular cylinder in orbital motion placed in a uniform flow in the Reynolds number domain of Re=120-180. Abrupt jumps between two state curves were found in the time-mean and root-mean-square values of the force coefficients under lock-in conditions. This study focuses upon the effect of abrupt alteration of transverse amplitude during computation. It was found that the solution tended to remain in the same state curve after amplitude alteration, inhibiting jumps between states.
