Abstract

A finite difference solution is presented for 2D laminar unsteady flow around a circular cylinder in orbital motion placed in a uniform flow for Re = 130, 160, and 180. Four cases displaying full lock-in are presented. The variation of time-mean and root-mean-square (rms) values of lift and drag coeffcients were investigated against the amplitude of vibration in transverse direction. Abrupt jumps were found in the time-mean and rms values of lift and rms values of drag. These jumps seem to be caused by a change in the vortex structure.
