Unlike the typical synthetic jet (SJ) which is a zero-net-mass-flux flow, the hybrid synthetic jet is a nonzero-net-mass-flux flow which was measured by the hot-wire anemometer. The results show the higher extrusion to suction volume ratio is 1.69 or volumetric efficiency is 26% in hybrid synthetic jets by integrating the velocity profile comparing with 19% in trigonally arranged one. Although the velocity along the central SJ axis decreases quickly, the velocity is higher than that along the trigonally arranged one.
