abstract = "![CDATA[This study presents the vortex formation in the wake of a cylinder undergoing streamwise oscillations in steady flow. It is found that the global wake structure possesses a spatial-temporal symmetry over N periods of cylinder oscillation when sub-harmonic synchronizations occur. The sub-harmonic synchronization modes are characterized by shedding of M pairs (1 ≤ M < N) of vortices in N periods of cylinder oscillation. The wake of M/N modes is comprised of vortex groups of M vortices arranged in a similar way to K{\~A}¡rm{\~A}¡n vortex street. The lift force shows excellent periodicity when lock-on occurs, and presents multiple peaks in its spectrum. The primary flow mechanism responsible for the sub-harmonic lock-on is identified as the interaction of the small sized shear bands induced by the cylinder oscillation with the shear layers induced by the steady flow.]]",
