This paper presents some results of a group theoretic analysis of a 2D cylinder wake under forced excitation. Both inflow and cross-flow cylinder excitations are considered. For inflow excitation, subharmonic bifurcations are shown to be the dominant dynamic phenomenon. The existence of the instability is confirmed by considering general maps equivariant relative to the general wake symmetry. Interestingly inflow (rather than cross-flow) cylinder oscillations are found to be more effective for the control of vortex shedding.
