Abstract

This paper presents a study on the control of two-dimensional vortex-induced vibration (VIV) of a single circular cylinder at a low Reynolds number of 100 using a synthetic jet (SJ) pair. To facilitate this study, a lattice Boltzmann method based numerical framework is adopted. While its strength is fixed, the SJ pair operates either in phase or anti-phase over a wide excitation frequency range. The effects of the SJ excitation phase difference and frequency are systematically investigated. Simulation results reveal that both the in-phase and anti-phase SJ pairs are able to mitigate the VIV at higher excitation frequencies, while either the cross-flow or streamwise resonance (associated with large-amplitude VIV) may be induced by the SJ pair at lower frequencies.
