Abstract

A finite difference solution is presented for 2-D laminar unsteady flow around a circular cylinder in orbital motion placed in a uniform flow in the Reynolds number domain of Re=100-180. Abrupt jumps were found in the time-mean values of the lift coefficient under lock-in conditions. The phenomenon was investigated by computations at different values of Re and amplitude of in-line oscillation and at different angles of attack. Plotting against ellipticity revealed two states of vortex shedding.
