Abstract
The flow is characterized with PIV phase averaged measurements. Results for the single synthetic jet are in good agreement with the ones present in the literature and a potential core region is defined for the phase averaged flow field of synthetic jets. Twin circular synthetic jets at jet-axes-distance equal to 3 and 5 diameters show the same behavior with respect to the single circular synthetic jet. Differently, strong interaction effects are seen at jet-axes-distance equal to 1.1 diameters: in particular a double vortex ring structure is visualized. This causes a different velocity distribution in the jet core, higher axial velocities and a lower jet width.
