A double-acting operation of a reciprocating jet-flow generator with hexagonally arranged hybrid synthetic jets is investigated experimentally. Unlike typical synthetic jets (i.e. zero-net-mass-flux jets), the hybrid synthetic jets are nonzero-net-mass-flux jets. Hot-wire measurements show enhancement of the extrusion volume to suction volume, and the ratio of 1.69 is achieved. The volumetric efficiency is 26% for the present hexagonally arranged hybrid synthetic jets, while it was 19% for the previous trigonally arranged variant. Although the velocity along the central SJ axis decreases rather quickly, the velocity is higher than that for the trigonally arranged variant.
