Synthetic ynthetic jet actuators are attractive devices for active flow control because, in contrast to many other actuators, they do not require a pressurized air source. Instead, they cyclically ingest and expel air from the external flow that is being controlled. To accomplish this, a piston or diaphragm is used compress and expand the volume of the actuator cavity. Various approaches to compress and expand the volume of the cavity have been explored including: speaker drivers,1 mechanical pistons2 and piezoelectric diaphragms.
